🚀Your technical partner in the AI era.
Today, producing code is fast. The real challenge? Architecture, data security, and your ROI. Don't hire a mere executor.
My mission: understand your processes, deliver a robust product (MVP), and integrate AI into your business. I apply this strategic vision daily as CEO of the Kréa agency and CTO of Kast.ai.
đź’ˇMY 3 PILLARS OF INTERVENTION:
1. SaaS Platforms & Product Engineering
Creating high-performance web apps. Instant user experience and scalable backend to manage complex databases and financial flows (Stripe).
2. Sovereign AI & RAG (Absolute Confidentiality)
AI without compromising your industrial secrets. I deploy internal search engines (RAG) and local LLMs (Mistral) containerized on your dedicated servers. Zero leaks to OpenAI or Anthropic.
3. Cloud Infrastructure & DevOps
A profitable app is online 100% of the time. Custom deployment (Hetzner/Vercel), Docker, and production automation (CI/CD via GitHub Actions).
đź› MY TECHNICAL STACK:
• Front: Next.js, React, TypeScript, TailwindCSS
• Back/Data: Node.js, Python, FastAPI, PostgreSQL, Prisma
• AI: Local LLMs, LangChain, Qdrant, NLP (SpaCy)
• DevOps/Quality: Docker, CI/CD, Vitest, SonarQube
🤝METHOD:Business audit ➔ Definition of a strict scope ➔ Fast and transparent delivery.
