About Lucas

Fullstack Developer for 3 years at a Group level, I have refocused on agentic engineering to design end-to-end AI systems – from architecture to production deployment.

I am involved in the design and management of AI pipelines (LLM, STT/TTS, conversational memory) using Claude Code, leveraging a solid technical foundation: React, Node.js, TypeScript, Docker, CI/CD.

Recent projects delivered to production: end-to-end AI voice assistant and OBS Streaming Toolkit orchestrated via Docker Compose.
