SERVICES

I take products from an empty repo to production — the app, the AI behind it and the machines it runs on. For businesses I build the software they run on: a CRM, a portal for their clients, an AI assistant, a site that gets found. If you have something you’d like to build, get in touch.

ABOUT

BIO

Five years owning products end to end: as a technical lead of teams of about seven, as the sole engineer for a long-term client, and now as co-founder and CTO of Metricor, whose ERP runs in production at a large ready-mix concrete producer.

On the AI side I’ve run a self-hosted LLM platform on a 16-GPU cluster, built agents with tool calling, memory and RAG, and fine-tuned Llama 3 8B for my MSc in Distributed Systems. Off the keyboard: table tennis and hiking.
