Full Stack Developer, available for work.

Focused on products and the systems behind them, working from Helsinki, Finland.

I build full stack products, ship AI agents, and own them end to end.

I'm a full stack developer with 4+ years of building production SaaS, from first commit to deployment. I've shipped 9+ products solo and led full stack engineering at a company that grew from 70 to 300+ people.

Most of my recent work is applied AI. I build LLM agents that call tools over Finnish and EU public data. Output guards and evals keep them from inventing sources. I also build MCP servers that automate delivery workflows, and RAG where it earns its place.

Under the AI, it's still full stack: React frontends, Node.js services, event-driven AWS and GCP infrastructure, and the SQL underneath. I once cut query times by 90% because slow dashboards keep me up at night.

I'm finishing a Master's in Software Engineering at the University of Turku. My coursework is done, and my thesis is on agentic source retrieval. I'm open to full-time full stack and applied AI work.
