Kiel · Software

Hello, I'm Kirill.

A backend engineer in Kiel, Germany. I wanted a personal website, even though it does nothing.

About me

Literally just a girl.

I write software for a living, mostly around Kiel, Germany. Most of my work is C#, with detours into Nix, Rust, and whatever the problem calls for.

Outside work I start more side projects than one person reasonably should: I'm literally just a girl.

Backend

I'm a backend person.

Most of what I enjoy building sits behind the interface: where the boundaries go and what happens when something breaks.

Architecture first

I like designing a system before writing it: clear boundaries and decisions I can still explain a year later.

Microservices

They're a tool, not a default. When a service deserves to stand on its own I'll split it out; when it doesn't, I won't.

DevOps, end to end

I'd rather own the path to production: CI/CD that ships on every commit and Kubernetes, even if it's just for fun.

Toolbox
