Luis David Garcia Lunar

Senior Full-Stack Engineer

I'm Luis, a senior full-stack engineer. For the past eight years, I've built software across the entire stack: from the data model and backend to the interface and deployment. My strength isn't "doing a little of everything"; it's taking ownership of complete systems and keeping them running in production.

I've built platforms that handle real-world volume: telemetry for thousands of vehicles transmitting several times per second, biometric onboarding with hundreds of thousands of verifications each month, and tax compliance systems used every day. When a backend slows down, I measure it; when something fails in production, I fix it. I prefer boring systems: the ones that don't fail unexpectedly.

To me, artificial intelligence is a tool that extends my capabilities, not a label. I've used it in both directions: integrating LLMs into real products — semantic search with vector databases, RAG — and working day to day with coding agents that expand how much I can build on my own. The difference between using it as decoration and using it as a tool lies in knowing when to trust the result — and that's learned through review.

Outside of work, I build to learn. Most of my side projects are works in progress — Godot games, tools for my own workflow — and I show them here as they really are.

I'm open to senior roles where the platform matters as much as the product. If you're looking for someone to take ownership of the entire system — and keep it running — write to me.
