Freelance Python, Django and AI developer.
I design and ship production systems, from back-end to AI agents. Available now, fully remote.
I design and ship production systems, from back-end to AI agents. Available now, fully remote.
REST APIs with Django and FastAPI, PostgreSQL, architecture, tests and deployment to production. I also take over existing codebases to make them reliable and move them forward.
I build AI directly into your products and your processes. Autonomous agents with the Claude and OpenAI APIs, RAG on your data, tool use, guardrails and production rollout.
I connect your tools together through APIs and webhooks. Data flows, CRM, scraping, business workflows. What takes you hours every week can run on its own.
React and TypeScript interfaces, iOS apps in Swift and SwiftUI. From mockup to the App Store.
Development and maintenance of a Django CRM in production for a repeat client. REST API with Django REST Framework, PostgreSQL, MeiliSearch search engine, webhook integrations, CI/CD on DigitalOcean. Working on an existing codebase with tickets and code review.
An autonomous AI agent on macOS. Screen perception through an 82-million-parameter vision model I trained myself, 46 ms local inference, keyboard and mouse control. It opened applications, wrote emails and switched between tools on its own, with no cloud. Proof that I can design, train and ship a complete AI system, from the model to the interface.
First place at Innov Hack Paris out of 150 participants, at my first hackathon. Back home, I designed and published the full iOS app in seven days, learning Swift and SwiftUI along the way. My execution speed, measured.
Built during Hack'Europe at Paris-Saclay, one of the largest student hackathons in Europe. Wattless tracked GPU spend and carbon emissions across several cloud providers. Eve, built on top of it, turned a natural-language description into a deployed, monitored AI model. I handled the front-end and the back-end with William Miserolle.
An e-commerce brand built alone: suppliers, packaging, online store, and 12,000 TikTok followers in fifteen days without ads. Proof that I understand my clients' business, not just their code.
My first clients at 16, knocking on the doors of local businesses in my region. Prospecting, negotiating, designing, delivering. Freelancing is not new to me, it is where I come from.
Alongside my client work, I run 20n, a personal research project in robotics: a motor control architecture inspired by neuroscience, tested in simulation on several robot morphologies in MuJoCo. It is my most demanding training ground: physics simulation, PyTorch, experiment pipelines, scientific rigour. Everything I learn there feeds into the work I ship for my clients.
Twelve years in the pool, since I was six. Waking up before dawn, cold water, the discipline of showing up every day.
I started programming at fourteen, during Covid. Alone with a laptop, I learned Python by building trading bots. The obsession never left.
At sixteen, still in high school, I knocked on the doors of local businesses in my region to sell them websites. Prospecting, negotiating, designing, delivering.
I stopped my studies at nineteen to go all in on code and research. That same year, my work earned me an invitation to a Y Combinator startup's hacker house and to Stripe Sessions.
I am twenty. I ship freelance work full time and keep my research going with 20n. The rest I learn along the way.
I taught myself everything. I am twenty and I know exactly what I want to spend my life working on.
Tell me what you need in a few lines. I reply fast and I will tell you honestly whether I am the right fit for the job. I work from Strasbourg, fully remote, at a day rate of €450.
