Building fast, reliable digital systems for European businesses — from backend infrastructure and automation to polished web applications.
End-to-end digital solutions tailored for modern businesses. Full cycle — from architecture decisions to production deployment.
High-performance APIs and business logic built with Python and Node.js. Designed to scale.
Robust, maintainable designs for SaaS products, internal platforms and microservices.
Turning repetitive manual work into reliable automated pipelines. Zero errors, less overhead.
Clean interfaces with solid backends. From quick MVPs to production-grade platforms.
Docker, Linux server setup, CI/CD pipelines and monitoring. Your app, always running.
Code reviews, threat modelling and systems built with a security-first mindset.
Writing production code since 2016 — started with automation scripts, grew into full-stack products and distributed infrastructure. Most of my work has been for clients across Finland, Germany and the Netherlands, either solo or leading small remote teams.
I value reliability and simplicity over hype. Boring proven solutions when they fit; custom-built when they don’t. Either way, things should work at 3 AM without my phone ringing.
Outside of code: cycling around Tallinn’s Old Town, electronics tinkering, good espresso.
