lee101··on Ask HN: What Do You Recommend for a Minimal Viable Launch for a SaaS?
I recently launched a cryptocurrency trading platform that offers ai based forecasts:

I would recommend building sharing into the platform and the process in contextual locations (when you signup/save/finish or go to do something else in the app as a popup for example), we also built a referral program into our MVP so users can earn real bitcoin if someone they refer becomes a subscriber to https://BitBank.nz

The referral program helped build links and we should have leveraged adding contextual hints to share and earn because for me the marketing has been a difficult process even harder than building the product and creating machine learning systems...

The ability for people to easily share and a strategy for building links is essential really to spread your product, there is often an initial spike of media attention and press and if your not properly prepared to capitalize on that then your out of luck when the traffic and hype tapers off as it does with the press, one risky thing about releasing an MVP really... although i think releasing an mvp is the way to go.

keep a close eye around any volatile times (potentially related to scares of manipulation) :) for checking up on trends and ai forecasts of the next few hours checkout https://bitbank.nz
lee101··on Ask HN: Which is the richest IT niche for a 2-3 years project?
I had some luck developing https://bitbank.nz an AI based crypto currency prediction platform, I do find that teaching AI can be a very hard subject to grasp for some but one of the most rewarding I'd say.

Lots of AI problems to solve in this space: anomaly detection to help understand risk, data collection/text mining to understand current trends in markets, clustering groups to find groups of for example high engaged users or people who should be shown ads instead of being pushed to pay for a product because they are likely not going to purchase ect

lee101··on Why ‘Free Trading’ on Robinhood Isn’t Really Free
I found trading on other platforms the exchange fees can eat most if not all the profits :/

Plug: to make good data driven trades check out https://bitbank.nz a machine learning prediction platform

lee101··on Ask HN: Who here has built a profitable startup while keeping their day job?
I built a high frequency cryptocurrency forecasting system https://bitbank.nz and few games in my spare time http://www.wordsmashing.com http://bigmultiplayerchess.com http://multiplicationmaster.com

hasn't made that much money but allowed me to get paid more at work and tipped our income over the edge so we could get a mortgage on our first house which was nice :) great decision and learning experience building products from the ground up and exciting/grounding interacting with customers who always like to push the limits of your product :)

I have noticed others who have a lot of job experience coding but not the business/product experience can find it difficult to prioritise things from a users point of view and or build reusable/extendable systems by anticipating how things are going to change in future.

Even if it fails terribly i think its a good learning experience and can work out in your favour... Word Smashing made some money from ads but $0 from listing on the android app store :D -$20 on app store ads actually...

lee101··on Launch HN: Toybox (YC S18) – Communicate changes to sites without writing code
I built something similar: with http://WebFiddle.net you can see what any site would look like with custom CSS and JS applied, its like an editor for changing the web/plugins/extensions ect. Used by technical types.
lee101··on Ask HN: What would you work on, if you had enough free time?
I have a few AI/ML pet projects and games http://wordsmashing.com http://bigmultiplayerchess.com http://multiplicationmaster.com

I have one project predicting cryptocurrency prices which makes money https://bitbank.nz, the games have no ads/attempt to charge and are more a labour of love :D

given more time i would venture into higher end 3D games and AI's, i also like to make things educational so i would love to make something biologically accurate, there are so many complex systems in real world biology that would make great games e.g for example a game centred around the life of one of these animals: meercat, beaver, bug/spider, ants.... the list goes on :D

lee101··on Show HN: Tetris with words – I created this small game, please give feedback
Hi I'm the creator of http://wordsmashing.com , awesome game, needs some music graphics sounds levels polish ect, I think it's interesting having to manually click to your word and click destroy, made the game feel a bit harder and slower paced to me but perhaps some advanced wordies would like that, I would make it automatic if 3 or more letters
lee101··on Ask HN: Anyone making money through algorithmic trading?
Check out https://bitbank.nz for high frequency cryptocurrency price predictions, we also have an api and some open source plugins for bots like gekko too
lee101··on Ask HN: What are you working on and why is it cool?
https://BitBank.nz a cryptocurrency prediction dashboard with live updating charts, API access, bulk data.

Its cool because i get deep into data engineering/analytics, machine learning/AI. Its using latest Google Cloud tech and my customers are always pushing me to better the product, myself and have done lots of work in open source.

Its interesting seeing what the customer perceptions of data science/prediction systems are and dispelling some of the rumors and snake oil e.g. forecasts get less accurate with time so people shouldn't trust out of date forecasts that are forecasting a long way into the future.

lee101··on Ask HN: How does a great resume look like? What are the best tools to make one?
Sometimes its real hard going talking to recruiters, you routinely get eliminated because of job description to C.V. skills match, e.g. i would get told either i didn't get a job or wouldn't get put forward to a job because i'm not "an Agile" or "an Node.js" despite doing JavaScript for around 8 years or so now. Sometimes the non technical recruiters are infront of some really lucrative clients who don't have a good grasp on hiring either.

A technical recruiter i like is aline lerner she has a blog http://blog.alinelerner.com/posts/ and founded interviewing.io some really good data driven insights there e.g. spelling on a C.V. matters more than what school you went too believe it or not.

I also have my C.V. online and found its worked well for me using that as a portfolio http://leepenkman.appspot.com its open source can be forked on Github/self hosted.

When deciding to hire a developer, what i personally look for is passion (something that stands out e.g. personal projects, good grades, good sounding application/well researched) and a depth/breadth of experience rather than a specific industry/exact match skill set which id say you demonstrate, you didnt go to a CS uni so its good you have some things about algorithms on your blog.

For depth id ask more specific questions around some of that e.g. i noticed the recursion post fairly light so id perhaps check for depth and ask more about caching, stack overflow, removing recursion with stacks/memoizing, traversals

many interviewers also ask compsci questions like how to write factorial recursively/non recursively which makes the interviews skew toward formal education.

for breadth id check for experiences: where/what/how/when/why (five whys) into experiences building things at a high level and what your experiences are of things relevant to this position.

breadth can be very high level and you may be asked abstract things like how do you think one of googles products works or how would you trouble shoot if say a large system like that went down.

Id say some advice would be to leverage your personal network, tell everyone your looking (already done here i suppose).

How have you been finding clients currently? you seem to be doing well, i run a SaaS cryptocurrrency prediction system https://BitBank.nz and basically everyone is from reddit/HN. Most jobs i've had either through knowing someone or applying, remote jobs have proved difficult even when i have done lots of open source work in and around the company without knowing anyone it seems a bit super hard, i settled on doing my own thing with BitBank.nz and contracting in person

lee101··on Launch HN: Hexel (YC W18) – Create a cryptocurrency for your community
Hi i'm founder of https://bitbank.nz a cryptocurrency forecasting platform, pre ICO.

I think more things supporting ICO's would be great e.g. like how waves has a decentralized exchange so that when you create a token on waves you can immediately monetize it.

I suppose theres a decentralised exchange for ERC20 tokens somewhere, but something that smoothes the entire end to end ICO process would be amazing.

lee101··on Ask HN: What's Your CI/CD Workflow for Your Machine Learning Projects?
Hi i'm founder of https://bitbank.nz a crypto currency live prediction dashboard/API/bulk data service.

Our system streams in market data from exchanges, creates forecasts with python/sk-learn and displays the data, we also have background processes that updates our accuracy over time once real data is available.

We test our code with the normal python unit/integration/end to end testing methods locally with local copies of all of our components (except firebase for live UI updates, we don't have a dev version of that yet just use live forecast data when testing the UI charts/display), would probably get expensive/cumbersome to setup dev environments with local firebases in them.

with deployment we simply ssh into machines, git pull latest code and supervisorctl restart so its fairly low tech, the forecaster has a roughly minute outage when we deploy new models because there is a decent process that computes and caches a data structure of historical features for use in the forecaster.

In terms of maintaining a reliable online stream of data input, feature computation/prediction pipeline we run the code under supervisor aswell as running a manager process under supervisor, that manager process checks if conditions are turning bad (OOM/no progress updates by the forecaster) and restarts things if anything goes wrong.

For testing we also use the standard training/test data split when running backtesting/machine learning optimisation algorithms to train parameters of the algorithm. If things perform better on training and test data over a long enough time period to build confidence then we will deploy a new model.

Using graphite/graphana to monitor prediction accuracy over time is a good idea as mentioned already :) and some kind of alerting/monitoring if things go down.

lee101··on Ask HN: Resumes that look good but professional too
I made mine with plain HTML JS and CSS it's available on GitHub and here http://leepenkman.appspot.com it hasn't costed me anything to host and is running inside a Google app engine free teir, I made it print friendly so you can control p print it if someone wants a PDF
lee101··on A $232M Cryptocurrency Fight Comes to a Close
Pretty amazing how they managed to raise this much money, i thought it would just fizzle out after they have raised such absorbident amounts of money they would run out of incentive. its not like a traditional acquisition where they are contractually obliged to make good on their ICO promises, ICO participants often forget they are in a sense buying part of a company that is up for sale (why?).

For a legitimate Crypto company that hasn't ICO'ed or raised money checkout my company https://bitbank.nz which is forecasting cryptocurrency prices :)

lee101··on Ask HN: What has HN given you?
most of our traffic and customers for our cryptocurrency trading stats dashboard and prediction engine https://bitbank.nz come from hacker news

Lots of interesting discussions and learning materials just like this post here allow learning from great people and can sum up to have a great benefit on your life/career

lee101··on Ask HN: How do you make money as a one-person data science business?
I'm founder of https://bitbank.nz cryptocurrency ai price prediction stats dashboard, API and bulk data service you can get to work lots with open source devs if you work lots on a specific niche and provide a good api
lee101··on Ask HN: How to launch an algo trading side project?

lee101··on Some Notes on the “Andrew Ng” Coursera Machine Learning Course
Ended up founding a ml startup predicting crypto currency prices https://bitbank.nz after finishing this course! such a good skillset to have I didn't know what I would do when I started the course just that I should learn this ml stuff
lee101··on Some Notes on the “Andrew Ng” Coursera Machine Learning Course
So many use cases! Take the course! You can use regularization to learn from small datasets by penalizing learning extreme biased feature weightings.

For finding a use case or at work just think of any normal problem like UI or ux design, or showing someone an enjoyable loading screen or funny picture, anyone can make something okay but to solve a problem close to optimally you start to need to gather data and do ml/ai

lee101··on Ask HN: Is AI overcrowded? Where should one look to be useful
What I did was to use ai to solve a problem in one of those upcoming areas I thought would become important (crypto currency trading in my case), I created a forecasting/ai prediction system, with a stats dashboard https://bitbank.nz, I charge a subscription fee and am transparent about the accuracy over time to build a long term loyalty.

This strategy worked well for me, use standard machine learning techniques to solve an existing problem, make the system as easy to interact with as possible, UI, API ect. Try to gather the customers data for them because a lot of machine learning is getting a good size dataset and aggressively training a flexible model on it. a good dataset can reduce friction if your customers can simply sign up and see value straight away.

I'd say (biased) do what I did... major in compsci which keeps things flexible, do your own research and create your own company to break into the ai/machine learning space which can be hard to get practical experience in for a new grad

lee101··on Ask HN: Where are you investing your hard-earned money?
I have been investing into creating my own business https://bitbank.nz a company that helps people investing in crypto currency. We provide live charts,apis, bulk data and ai forecasts
lee101··on Ask HN: Best Outsourcing Practices
In trying to get more people involved in my crypto currency prediction and stats system https://bitbank.nz on the marketing side I created a referral program which helped my normal customers be a bit more sharing but pro marketers eg ones on freelancer want more stability than that and a more well defined task than being an affiliate, which is fair enough, they work for money and Im happy to take on the risk of my site not converting people to customers.

It's hard however to invest in people upfront when they don't know where to start

It's good to outsource if there's a literal to the letter description or if it's something outside your forte, design and marketing I in my case,

I have had a good experience running design contests on 99 designs or using their small design touch-up service. I ran a contest to get a logo designed for a game I made which paid off (http://wordsmashing.com) it requires active management otherwise the designs drift toward something unwanted, id say run a blind contest too because designers copy each other and end up with less variety otherwise.

I'd feel bad not paying proper rates but if it's something on the verge of automation you could try mechanical Turk.

Let me know what you find! the type of sporadic tasks I would have are things requiring non trivial domain knowledge and self direction, things like article marketing or link building which can be hard to find someone trustworthy and self directed on a party time basis

lee101··on Firebase: Streamline Your TypeScript Development of Cloud Functions Code
pretty hipster... does anyone use visual studio code???

I want a python and other languages live subscription API and the ability to offer that API access to my customers of https://bitbank.nz (cryptocurrency forecasting service), i don't really see what the selling point of firebase cloud functions is yet.

lee101··on Ask HN: Why aren't I getting responses to my Who Is Hiring applications?
I spent a bit of work on my resume which i made open source: http://leepenkman.appspot.com/

Your website www.getfractals.com and https://beaver.digital/ looks beautiful and works well, with your C.V. your marketing yourself just as you would market a company, make your C.V. hip like your websites

Also do as many comments suggest here, reorder things, i think your website and fractal experience is a huge selling point, My games probably got me a job here at Weta doing visual effects, Also Weta is hiring https://careers.wetafx.co.nz/jobs?search=&sort=recent

Your experience developing fractals would be useful e.g. in writing Shaders here in Visual effects i'm sure.

I agree you should try and tailor to a specific job e.g. that might mean removing things about hardware/fabrication if its not relevant to a job and adding other things that are.

lee101··on A decentralised Universal Basic Income platform based on personal currencies
Just my opinion but I believe the inflationary nature proposed here will create a pressure to immediately swap your basic income to other crypto, there are too many cons in holding this coin eg you don't know who will accept it and for a decentralized system is too personal, I understand that with the level of specificness of every person having their own coin politics will come into play with validators Nations refusing each others coins

Interesting concept that the validators are incentivized not to validate the wrong people but perhaps need more incentive to validate people, perhaps the validators would start printing their own money and automatically disperse it, fairly dangerous ideas but we are all lucky the ball is rolling on this.
