I architect and ship .NET + GenAI systems that hold up in production.

The senior you bring in to ship a critical technical subject properly — from scoping to production, no tech debt and no lock-in after handover. 9 years, ex-CTO, network tech integrated into the Rockstar Games ecosystem.

Florian Sola — Senior C#/.NET/GenAI Developer — Lead Engineer & Software Architect

9 years of mission-critical .NET. 6 key product builds shipped solo in 9 months — client missions, personal products and R&D; 4 integrate GenAI, scoring, RAG or Machine Learning.

Available — Freelance & consulting · open to exceptional full-time roles

Permanent (full-time): Package open to discussion — scope, location, equity
Freelance: €450 — 650 ex. VAT/day · €450/d standard · €550-650 high-perf, full ownership
Geography: Remote France & Europe · hybrid Montpellier / Nîmes only.

Portfolio proof, not an AI promise.

Recruiters should be able to answer one question fast: what was actually built? This portfolio surfaces context, constraints, numbers and architecture decisions instead of just a technology list.

6 key builds in 9 months — OneRP, SaleCast, Matchr, PromptVault, MyRoadTrip, Poisson Engineacross client work, personal products and R&D, with constraints and tradeoffs explained on project pages.
Real constraints — 2,048 target concurrent connections, 100,000 entities at 60 FPS, 12 forecasting algorithms, ATS scoring and billing: each project starts from an actual product problem.
Fast recruiter read — the home page gives the signal; projects and case studies provide STAR detail, numbers, tradeoffs and public code where available.

Good fit

Product Sprint (short fixed-price) — 10 days at €4 500 (negotiable based on scope). Scoping, architecture, code, staging/prod deployment, team handover.
Long mission — 3-12 months, day rate €450 — 650 ex. VAT/day.
Not a fit — pure ML research / fine-tuning, frozen legacy code without evolution room, missions where I would be the only person able to understand the code.

Note about the English version — the hiring-relevant pages are in English: about, for recruiters, projects, services, case studies, blog summaries, FAQ, the CV, PDF resume, JSON Resume and vCard.
