About Jean-Patrice

Lead fullstack developer in TypeScript and Applied AI. For 11 years, I've been designing, coding, and deploying web products, from MVP to scaling.

My greatest value is in ambitious web applications (SaaS, platforms, back-offices) and the concrete integration of AI into your products (LLM, RAG, agents, automation). Not demos, but code that runs in production.

Recent highlights:
Jimini AI (legaltech): Tech lead for a legal AI platform. SST, Drizzle, TypeScript, OpenSearch, Auth0, Docker.
Arcads: AI video generation platform for advertising and content. Nest, Next, AWS, SST.
Cantem: My studio since 2015, where I lead teams and deliver client projects across various sectors.

Stack: TypeScript and Node.js, Next.js, React and React Native, AWS and SST, Postgres and Drizzle, Docker. AI side: OpenAI, Anthropic, RAG, embeddings, agents, vector search.

In practice, you work with a single person who frames the need, writes the code, and stays close to you from the first discussion to delivery. Available full remote, with potential for travel.

Tell me where you are, and I'll tell you how I'll tackle it.
