Codeborne
Software developer
Built client web applications across frontend and backend, with clean code, concise tests and pair programming at the center of the work.

Tallinn University
BSc, Computer Science
Studied computer science while starting my career in software engineering.
WebAssembly thesis
Built and ran five algorithm benchmarks across JavaScript, Rust, C++, AssemblyScript and C# in desktop and Android browsers. The results showed where WebAssembly delivers real speedups, and where JavaScript holds its own.
02 / PROJECTS
Selected projects.
A couple of things worth exploring.
01 / SELECTED WORKPersonal project
ampsu
I’m building Ampsu to make food logging less of a chore. It knows European barcodes and learns calorie needs from your log and weigh-ins.
02 / SELECTED WORKBuilt at Codeborne
A free alternative to Phrase for editing JSON translations and managing changes through GitHub or Bitbucket.
03 / ABOUT
Beyond the commit history.
I like understanding how things work all the way down.
That curiosity takes me from product code into Linux, servers and self-hosting. I daily-drive Linux, and Kotlin is still my favourite language.
At work, I’ve built across backend, frontend and infrastructure. Outside it, I keep making things of my own.
