About Me

I keep the tech out of your customers' way. Signups work, payments go through, APIs stay responsive, and deploys don't cause headaches, so we can release faster and keep users happy.

I moved from mechanical engineering into software because building reliable systems scratches the same itch: clear specs, tight feedback loops, and parts that fit. Writing small Python scripts and PHP pages turned into full APIs, and I never looked back.

Today I help product teams ship APIs they can trust. I design clear endpoints, plug in payments and keep systems steady with queues, caching, and good observability.

How I work: keep it simple, name things well, write tests that matter, and automate what's repeatable. Small PRs, readable code, and deploys you don't have to babysit.

I'm currently pursuing an MSc in Computing Sciences at the University of Vaasa and sharpening my C/Linux fundamentals. It helps me reason about performance, reliability, and what's really happening under the hood.

Based in Vaasa, Finland. Open to remote. If you're building a product that needs calm, dependable APIs, let's talk.
