About Me

Who I Am

Full-Stack TypeScript Developer

I build production-ready web applications with TypeScript and Next.js, Python APIs with FastAPI and Django, and deploy everything with Docker and CI/CD pipelines. Security-first approach from day one.

Every project includes comprehensive English documentation, automated testing, type safety, and GitHub Actions CI/CD. No shortcuts, no technical debt, just production-ready code.

Based in Oulu, Finland, working with clients internationally. I prefer direct communication and building things that actually work.

Full-Stack TypeScript

TypeScript throughout the stack with Next.js, combined with Python APIs. Type safety, Docker containers, and automated CI/CD pipelines for every project.

Clear Documentation

Comprehensive README files, API documentation, and code comments. Your team won't have to guess how things work.

Practical Approach

I use tools I know well rather than chasing every new framework. Shipping working code beats theoretical perfection.
