davidajackson··on Ask HN: What do you like to use for state management with React?
What's your opinion on MobX versus Redux? I've used them both and MobX just seemed more compact.
davidajackson··on Roast My Job Offer
What's the salary range? Asking for a friend. Most people I know who are really good won't engage in early chats without a salary unless you're a big co.
davidajackson··on Ask HN: Where do you find meaningful part-time tech jobs?
I know HN is probably against self promotion like reddit is, but maybe you could drop your LinkedIn into the prompt. Personally most part time jobs come through references, so building your connections on here is probably one way.
davidajackson··on Ask HN: What you up to? (Who doesn't want to be hired?)
Is it really unintuitive? Most Americans only save about 7% of their income IIRC, wouldn't it make sense that they would mismanage most windfalls by default? In recessions, this number jumps up dramatically, proving that it's mismanagement that contributes.
davidajackson··on Ask HN: Where do you find part time jobs?
"We'll cover that next week."

davidajackson··on Ask HN: Freelancer? Seeking freelancer? (September 2021)
SEEKING WORK Location: West Coast, USA

Remote: Yes

I specialize in Ethereum smart contract integrations and architecture. If you're looking to build, test, or launch smart contract based products, I can help. If the past, I've helped multiple YC crypto companies launch and I specialize in Ethereum/solidity. I also run https://www.blocktimize.io/, which automates a lot of the process of smart contract architecture setup if that's of interest. I am also a fullstack engineer with substantial React + React Native + Node experience.

davidajackson··on Ask HN: Is experience in raising a startup valuable in a CV for a soft. eng.?
I wouldn't worry about interviewers frowning on your startup, as long as you're learning. The ones who will you won't want to work for. I have seen interviewers make the mistake of thinking someone is inexperienced just because they haven't 'worked on a team of X size' but as long as you can talk about the technical side and what you did/learned you should be fine.
davidajackson··on Ask HN: Should I even bother competing for React jobs?
Probably the most actionable advice I can give is don't apply to jobs that take 3 hours to apply to. I forget what sites it is, but some just have you upload your resume once. Don't do the ones that force you to fill out all experiences manually, unless you really want the job.
davidajackson··on Ask HN: Should I even bother competing for React jobs?
If you don't want to compete on React jobs: Optimize for companies that do leetcode interviews, because it's 45 minutes versus sometimes 3-5 hours just for a first stage. Don't do long take homes, unless you really want the job. Take homes are always eeking one more hour out of you, especially when you get to the 'nice to haves' sections...

If you do want to compete on React: Find a way to set yourself apart. Maybe start a blog on React basics and start posting it here on HN? Then drop that in your job application process somehow when you have enough articles/projects.

davidajackson··on Launch HN: BlackOakTV (YC S21) – Netflix for black people
Seems like there's a lot of controversy in the comments. But controversy aside:

Did any of your investors ask you why Netflix can't just add a section like what you're doing? How do you respond to that from a business standpoint?

davidajackson··on Show HN: Slice – Decentralized payments infrastructure based on fractional NFTs
Interesting concept, I have a few questions/feedback. You should add some documentation with code examples! Most devs will want to glance over the code of the contract, I didn't see that listed. Things I want to know after reading:

1. What is the recipient of a slice for payments? Is it a wallet crypto address/ENS domain? Or is it a function in a larger smart contract? It seems this would dictate whether the sender can treat it like a normal ETH/token send or whether they have to use a dApp to send payments. Curious whether senders of payments are locked into your infrastructure or not.

2. What is the process of slice creation? Does one party decide which other parties get a piece of a slice initially, or just own 100% initially?

Somewhat related, I am building infrastructure tools for smart contracts (https://www.blocktimize.io/), and I'm looking for Beta testers who are launching smart contracts -- is there an email I could reach you at?

davidajackson··on Ask HN: Who wants project feedback? (August 2021)
Who is your target audience? I have never worked in a large company, but I wouldn't be surprised if a flow chart generator is something large companies would use.
davidajackson··on Ask HN: Who wants project feedback? (August 2021)
Cool idea. Have you thought about the ability to export to a PDF?
davidajackson··on Ask HN: Who wants project feedback? (August 2021)
Thanks. I'm in the process of writing the documentation, especially for the webhooks format.
davidajackson··on Ask HN: Who wants project feedback? (August 2021)
I'm building Blocktimize, which lets you launch dApps faster and monitor them. You can check it out here: https://www.blocktimize.io/

This is probably mostly relevant for blockchain devs, but would love feedback.

davidajackson··on Ask HN: Share your side project
I've been building Blocktimize, which is a no-code solution for smart contract integrations on Ethereum. https://www.blocktimize.io/

Using Blocktimize, you can receive webhooks for smart contract events instead of having to connect a node/scan blocks, connect smart contracts to analytics engines like Amplitude, and finally I'm working on adding daily and weekly reports for smart contracts.

davidajackson··on Can Smart Contracts Make the World 10x More Efficient?
The size/capital of the insurers is potentially irrelevant with smart contracts, as a small insurer with a small amount of capital can be just as reliable as a large one -- open source code enforces payouts so it likely won't matter.

This doesn't apply to all industries, and I agree about your example of crops. But specifically in finance, there will be a lot of 10x's.
