xk4rimon Ask HN: Who wants to be hired? (September 2026)

  Location: Abu Dhabi, UAE (UTC+4, strong US morning overlap)
  Remote: Yes (100%)
  Willing to relocate: No
  Technologies: TypeScript, React, Next.js, React Native, Expo, Supabase, PostgreSQL, Python, Astro, self-managed Linux

I'm a founding engineer working part-time, remote, on monthly output-based retainers. You define what needs to exist. I own it from schema to deploy, and I bring the product calls back to you.

What I've shipped:

1. Tenpo (youth-sports marketplace, San Francisco). Built the production verified-reviews system in a 30-day contract: schema, APIs, moderation dashboards, and automated publish and notification flows. Every read and write path secured with Postgres row-level security. 200+ merged commits, and I closed every finding from the CTO's line-by-line review.

2. The Scientific Place (my own edtech platform). 240,000+ visitors on $0 marketing, featured in Morning Brew and Smashing Magazine. A constraint-satisfaction engine generates procedural puzzles, and a separate cryptographic layer handles anti-cheat. Peaked at 11,000 visitors in one day on a single VPS.

3. Himaya71 (emergency response). Founding engineer on a live pilot. Client-side indoor navigation that reroutes around active fire zones in under 100ms, a YOLOv8 headcount pipeline over RTSP streams, and a custom Android background service for persistent GPS. Won a $5,400 prize and a signed pilot contract.

4. AIWAY (fintech). Designed and ran four interconnected production systems as the sole engineer at near 100% uptime, including a Prophet forecasting engine and a Telegram trading terminal for Binance and Bybit.

5. ASOgency (app-marketing agency, Dubai). First tool live five days after onboarding: a Figma plugin that localizes app screenshots across 39 languages in a single pass, replacing hours of manual editing.

I use AI tooling like autocomplete. It makes me faster, but it doesn't make the decisions, and nothing ships that I haven't read.

The shape: async, billed monthly against agreed output rather than hours. Long-term preferred. Cash, no equity. Part-time because I'm finishing a software engineering degree (4.00 GPA). UAE Golden Visa, self-sponsored.

Founders making their first engineering hire are picking between two bad doors. Either someone cheap who leaves a mess, or someone great you can never afford to lose. I'm the third door.

I work like a technical co-founder, and I'm built to be replaced. I ship your production v1, and when the product proves out, I help you stand up your in-house engineering team that takes over from me.

Who this is for: Funded founders with no engineering leadership yet who need real software shipped before the next raise.

What I've shipped as the sole or founding engineer:

1. An edtech platform bootstrapped to 240,000+ users on $0 marketing, fully organic. Custom constraint-satisfaction engine for procedural puzzles, with a separate cryptographic anti-cheat layer. Peaked at 11,000 users in one day on a single VPS.

2. A live emergency-response pilot. Client-side indoor navigation with sub-100ms routing around active fire zones, a master-worker computer-vision pipeline over RTSP streams, and a custom Android background service for persistent GPS. Won a 20,000 AED grant and a signed pilot contract.

3. A four-system financial intelligence suite at near 100% uptime. Forecasting on Prophet, a news aggregator with cryptographic deduplication, and a Telegram trading terminal for Binance and Bybit.

4. Internal tooling for an international marketing agency. First tool live on day five. One of them translated content across 39 languages in a single pass, replacing hours of manual editing.

I use AI tooling like autocomplete. It makes me faster, but it doesn't make the decisions, and nothing ships that I haven't read.

Async, remote, long-term monthly engagements. Cash, no equity. UAE Golden Visa, self-sponsored.

A 240,000-user platform. A live emergency-response pilot. A four-system trading suite. All built by one engineer, and that engineer is the one you'd work with.

I work like a technical co-founder. You bring the product. I bring the engineering and the judgment. I don't take tickets, I take ownership of the thing and ship it. "Karim requires zero hand-holding" is how my last CTO put it.

Proof of work, as the sole or founding engineer:

1. The Scientific Place (edtech). Bootstrapped to 240,000+ users on $0 marketing, fully organic. Custom constraint-satisfaction engine for procedurally generated puzzles, with a separate cryptographic anti-cheat layer. Peaked at 11,000 users in a single day on one VPS. Astro, React, Svelte, TypeScript, Python/FastAPI, MongoDB.

2. Himaya71 (emergency response). Founding engineer on a live pilot. Client-side indoor navigation with sub-100ms routing that reroutes around active fire zones, a master-worker computer-vision pipeline processing RTSP streams, and a custom Android background service for persistent GPS. Won a 20,000 AED grant and a signed pilot contract. React Native, Expo, Python, YOLOv8, Hasura, Docker.

3. AIWAY (fintech). A four-system financial intelligence suite I designed and deployed end to end: a forecasting engine on Prophet, a multi-source news aggregator with cryptographic deduplication, a Telegram trading terminal for Binance and Bybit, and self-healing infrastructure at near 100% uptime. Python, Prophet, Telethon, CCXT.

4. Internal tooling for an international marketing agency (under NDA). First tool shipped five days after onboarding, then grew into a set the team ran daily. One of them translated content across 39 languages in a single pass, replacing hours of manual editing. React, TypeScript, Python, Docker.

I use AI tooling like autocomplete. It makes me faster. It does not make the decisions, and nothing ships that I haven't read. The architecture and the judgment are mine. I use Claude Code daily.

I work async and own the technical calls, then bring product decisions back to the founder. Greenfield, an existing production codebase, or an AI-generated prototype that needs to become real are all fine starting points.

UAE Golden Visa, self-sponsored. Looking for long-term monthly engagements.

I'm a Founding Engineer for non-technical founders. You focus on the business; I take full ownership of the technical stack from architecture to shipped product.

I don't clear tickets. I ship products from zero. "Karim requires zero hand-holding" - my previous CTO.

Proof of work:

1. The Scientific Place (EdTech): Bootstrapped to 230,000+ organic users as the sole engineer. Astro, React, FastAPI, full stack from scratch.

2. Himaya71 (Emergency Response): Architected a sub-100ms indoor pathfinding engine for firefighters running on low-end hardware. Won 20,000 AED at UAEU and landed a pilot contract.

3. AIWAY (Fintech): Built an AI-powered crypto trading engine with real-time forecasting, multi-exchange execution, and self-healing infrastructure. Near 100% uptime.

4. Most recent: Shipped production internal tools for a marketing agency within 5 days of onboarding. Solo engineer, zero ramp-up.

What I offer:

- Total autonomy. I operate async. I don't need meetings to work; I need a vision to execute.

- Speed. 0 to 1 is my default mode.

- Stability. UAE Golden Visa holder, looking for long-term retainers.

xk4rimon Show HN: Turn any number into a complicated math expression

Please don't blindly use ChatGPT for math. If you still wanna use it, use the Wolfram GPT here: https://chatgpt.com/g/g-0S5FXLyFN-wolfram.

xk4rimon Show HN: I made an interactive math crossword puzzle with infinite levels

Hi! They are randomly-generated but in a controlled way (e.g. I tell it to make 1 equation with 1 option, or 5 equations with 8 options for some level).

I've made the first few levels easy on purpose just to get people used to the game.

And yes, it gets very tricky. Specially after 20-25 puzzles. :)

TIL. Thank you very much for sharing this!

You can additionally use your toes to count to 20. That will be 1,048,576 possible finger arrangements.

Yeah, it's like a dark-mode piano. They still exist today but for the harpsichord.

Interesting. That's not the first time I get this suggestion. So what's the solution here? Should I just remove the filter?

Edit: I ended up removing the filter.

Hi. OP here. I'm the developer of the website.

Don't worry. I'm not a bot. I'm just very new here; this is my first comment (and this is my first submission to get that many comments).

I've decided to start engaging with HN from today. You'll see me post other links from other websites soon.
