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.

I am a high-agency Founding Engineer. I act as a "One-Man Agency" for non-technical founders: you focus on the business/sales, and I take full ownership of the technical lifecycle (Architecture, DevOps, Frontend, Backend).

I don't just clear tickets; I ship products. "Karim requires zero hand-holding" - My previous CTO.

My Proof of Work:

1. The Scientific Place (EdTech): Bootstrapped a platform to 230,000+ organic users. Handled 100% of the stack (Astro/React/FastAPI).

2. Himaya71 (Emergency Response): Architected a sub-100ms indoor pathfinding engine on low-end hardware. Won 20,000 AED in funding from UAEU (3rd Place).

3. AIWAY (Fintech): Built an AI-powered, self-healing crypto trading engine with real-time forecasting, multi-exchange execution, and noise-resistant news signal processing.

What I offer:

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

- Speed: I build from 0 to 1 by default.

- Stability: Golden Visa holder (UAE), looking for long-term contracts/retainers.
