This site is a running notebook of projects, prototypes, and ideas.
It’s where I design, build, document, and release the things I work on and find interesting.


about

Markus Vallin

Github Linkedin

Software developer based in Helsinki, Finland.

I focus primarily on backend development, designing APIs, services, and systems that are maintainable and easy to extend. I enjoy working across the full stack when needed, but my main interest lies in building the infrastructure and logic that powers applications.

Currently I am finishing my ICT Engineering degree (Software Engineering) at Metropolia University of Applied Sciences.


what I do

  • backend development and API design
  • system architecture and service design
  • automation and CI/CD pipelines
  • databases and data processing
  • full-stack web development when needed

I prefer building systems that are simple and maintainable and also like automating the developing and integration process.
