About me

I build complete software with AI inside: web apps and AI agents, from backend to deployment. Before that, 12 years in IT infrastructure for Ernst & Young (EY), IBM, Kyndryl and Atos: networks and data centres, server configuration, security, large enterprise projects (9 years in 3rd/4th-line support).

What I've built:

Onelo — a multi-tenant SaaS platform. Sign-up and login, Stripe Connect payments (subscriptions, refunds, customer portal, invoices), EU VAT, feature management. Python/FastAPI backend, Next.js + React + TypeScript dashboard, PostgreSQL. Payment webhooks are idempotent — when money is involved, a duplicate event has a real cost.

Turingo — an AI agent for macOS. Streaming voice pipeline, Claude API with tool calling and structured output, MCP, on-device speech recognition (Whisper/CoreML) or Groq, cloud or local text-to-speech.
