À propos

Introduction

I build AI systems that actually work in production. LLMs, agentic workflows, cloud architecture. I work with companies that want to move fast on AI without breaking what's already working. After 10+ years across CTO, Cloud Architect, and ML Engineer roles, I stopped doing just strategy. I wanted to stay in the code, close to the product, and deliver end-to-end. That's why I went freelance. Today I work with tech teams on designing and shipping LLM-powered agents and agentic pipelines, cloud architecture on GCP and Azure, FastAPI and Python backends integrated with AI models (OpenAI, Anthropic, Google, Mistral), and bridging the gap between AI prototypes and production-grade systems. I'm comfortable owning a full workstream from architecture decisions to delivery, or plugging into an existing team as senior technical muscle. Stack: Python · FastAPI · LLMs (OpenAI, Anthropic, Google, Mistral) · MCP · Azure · GCP · Docker · PostgreSQL · Airflow · NestJS If you're building something with AI and need someone who can both think and execute, let's talk.
