// Software Engineer · Berlin

I build backends, tools
and full-stack apps.

I'm a Software Engineering student in Berlin. I mostly work with Rust, Go and TypeScript, and I learn best by building real things: a published Rust crate, a few backend APIs, and some serial-port code that talks to physical machines.

A little about me

I'm studying Software Engineering at GISMA University of Applied Sciences in Berlin, but to be honest, most of what I know comes from building things on my own. I've written backends and command-line tools in Rust and Go, full-stack web apps in TypeScript, and I've also played around with a bit of machine learning.

The work I enjoy most is the kind that's close to the hardware: a network traffic analyzer, serial-port code that lets software control physical machines, and small tools I actually use myself. I like building and learning alongside a real team.

What I've worked on

  1. Working Student, Software & Operations

    Part-time

    Bar & Entertainment Venue · Berlin, Germany

    • Built small internal tools that made the day-to-day work at the venue easier.
    • Wrote serial-port code so our software could talk to the physical machines while they were running.
    • Automated a few repetitive tasks on Linux.

  2. Open-Source Developer

    Ongoing

    github.com/sw3do

    • I've put 30+ public repos on GitHub, written in Rust, Go, Python and TypeScript.
    • Published a Rust library to crates.io, and I keep making small tools that solve real problems for me.
