Andri Butros

Fullstack engineer — web, embedded, and AI

I design, build, and run production systems end to end — web frontends, Node.js and Python backends, data architecture, and the embedded firmware that talks to hardware in the field. Most of what I ship, I own alone: from first commit to the thing running unattended.

What I build

Solo ownership

Nine production systems, designed and maintained alone — architecture, implementation, and the on-call pager when something breaks.

Full stack, literally

The same week can mean debugging an ESP32 interrupt handler in C++ and shipping a React feature — with the Node.js and Python services in between built by the same hands.

Applied, not theoretical

Game dev and mobile app roots before this — Android, iOS, Windows, Linux. AI work follows the same pattern: self-hosted models, not API wrappers.

Self-Hosted LLM Chat

2026

End-to-end chatbot built on a self-hosted Ollama deployment — model serving, a thin API layer, and a chat UI, with no third-party inference API in the loop. Feedback from conversations feeds back into the index to improve retrieval over time.
