About Me

Who I Am

Full-Stack Developer & AI Automation

I build full-stack web apps, AI-powered automation pipelines, and live trading systems. TypeScript, Python, FastAPI, Django — deployed with Docker and GitHub Actions CI/CD.

Security-first from day one. Every project ships with proper input validation, rate limiting, and production-ready error handling. No shortcuts.

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.
