Freelancer profile translated to English.

Description

I design and deploy data/AI tools for vertical businesses where generic SaaS solutions fall short. My focus: delivering products used in production, not just POCs.

What I do well:

• AI Document Extraction (PDF → Structured JSON via Claude API) — deployed on Komptas, multi-tenant invoice management in production

• Applied Probabilistic Modeling — Benter, conditional logit, Harville, Kelly, 128+ variable feature engineering (Oracle project, prediction)

• Claude Code Agents, custom MCP servers, RAG, operational prompt engineering

• Full-stack for rapid delivery: FastAPI + React + TypeScript + Expo, deployed on Render / Vercel / Supabase

An intentional hybrid profile: racehorse trainer (France Galop license, 8th season) + solo data/AI builder since 2023. 10+ projects built solo, from conception to deployment. This dual role has taught me to deliver under pressure and make the complex understandable.

I work alone, fast, and without the fluff. I prefer focused, high-impact engagements: AI audits, MVPs, LLM integrations, tech consulting — rather than long-term full-time engagements.

Management of a complete structure: team (jockeys, lads, administrative staff), finances, daily operations, thoroughbred import/export customs, owner relations, and institutional representation (France Galop). 8 seasons in flat racing. This experience taught me to deliver under pressure, manage operational risk, and make complex subjects understandable for non-specialist stakeholders.
