Who am I?


I'm Hannu, currently working at Pinja as a software developer. Almost everything to do with STEM has always excited me. When I started coding in upper secondary school, I found myself really enjoying it – now I'm a software developer!

What I can do?


I've worked with many programming languages, frameworks and programs. Currently I code mainly .NET stuff with some JavaScript here and there.

Things I'm more or less familiar with: C#, ASP.NET Core, EF, Visual Basic (with Web Forms), JavaScript, TypeScript, Rust, NestJS, Node.js, React, React Native, Python, Swift and Kotlin.

I also have experience from CI/CD, Docker containers and Linux servers.
