An AI-built MVP that barely worked, rebuilt into a stable production platform: PHP/Laravel backend, Hetzner deployment, and five AI assistants on Claude, DeepSeek, Kimi and Qwen.
Rebuilt in 6 months. Campaign setup fell from 10–15 minutes per platform to a few minutes overall. Used in-house on $500K+ a year of ad spend per platform.PHP · Laravel · React · Claude API · Hetzner · Nginxdigitalyst.co ↗

I'm Samer, a full-stack developer based in Paris. For five years I've built web products with React, Next.js, Node.js, TypeScript and PHP/Laravel: 25+ apps across AI, marketing, health and aviation.
I like owning a product end to end: architecture, backend, interface and deployment. I've taken a half-working MVP to production, built the backend behind a 1M-download app, and led teams of up to five. I taught full-stack development for two years, so mentoring comes naturally.
I took over an AI-built MVP with barely any working features and turned it into a stable platform, mostly alone on the backend, with no missed deadlines.

Teams of 2 to 5 developers
How we work together.
I send short written updates and quick screen-recorded walkthroughs, so progress is visible without pulling anyone into a call. When something needs a live conversation, I'm there.
I work in your tools: Slack, Teams, Jira, Trello, Asana, WhatsApp, Signal or Telegram. I take tickets from your backlog, review code and answer the same day.
Week 1: access, a walk through the codebase, and one small change shipped. By day 30: I own a part of the product and we have agreed a plan for the next quarter.
I work on a contract basis through CodinHex SAS, my own French company, full time or part time depending on what your team needs. I invoice monthly, so there is no payroll setup on your side.
Yes. I hold my own work authorisation in France, so there is no visa or sponsorship process for you.
If you want me to. I ship in small, regular releases and document as I go, so the work is easy to hand over at any point, and I'm glad to stay on as the product grows.
