I'm a senior AI engineer with over a decade in software. I build agentic AI products and take them from the first version to something customers rely on every day.

Right now I'm at Roccnova, an AI tool for B2B sales teams. I designed the multi-agent system there, where three AI agents work together and a person approves the important steps. I also built Voice Nova, an AI phone agent that replies in 320 ms and books meetings, plus a chat feature that lets people ask their CRM questions in plain language. Much of my time goes into making sure the AI holds up once it's live. I track every call with Langfuse and OpenTelemetry and run evals before each release.

Before that, at Roccomedia, I built an AI analytics agent that answers questions on 100k+ rows of sales data with charts, and chatbots for 8+ clients in different industries. I also worked on Reico, a busy online pet food shop with millions in monthly sales.

I started out building tools for online stores. I was a founding member of ShopiDevs, later led a team of 4 developers, and was lead developer of Slider Revolution for Shopify, which has 3,000+ installs and a 4.8 rating.

I'm most interested in agentic AI, RAG and LLM evals, mainly in Python and TypeScript. I'm happy to relocate to the UK or Europe, or work remotely.
