Most of my work right now is building AI agents and Claude API integrations. About ten years in software — full-stack web, Python, and shipping SaaS products end to end. The part I find most interesting is orchestration, retrieval, prompt design, and the unglamorous reliability layer (retries, state handling, error recovery) that turns a demo into something that actually runs in production. The boring stuff is where the real craft hides. Usual stack: Next.js, TypeScript, Python, Claude API, Firebase or Postgres, Stripe, n8n. A few things that matter to me: scoping honestly, so if something is going to take longer than you hoped, you hear it from me early rather than at the deadline. Working with non-technical founders without making them feel stupid for asking questions. And leaving a client genuinely happy matters more to me than the size of the invoice — I'd rather charge a fair price and have you come back next year than squeeze every euro out of one project. Based in Oulu, Finland. Happy to do a short call before any commitment, easier to figure out fit in 20 minutes than over messages.
