About me

Hi, my name is Eugene and I'm a software engineer. I like math, science, algorithms, good UX and other boring things. I started working as a developer in 2011 and received my system engineer diploma from BSUIR in 2013. Most of my experience has been as a fullstack developer (Node/Java + Frontend). I'm especially into functional programming, security engineering, k8s, cloud platforms and graphics work with Three.js/WebGL. Currently, I'm working as a fullstack developer, mainly with Svelte, React, TypeScript, k8s, and AWS/GCP. I enjoy taking messy product and platform problems, building the first useful version, then hardening it into production software that teams can operate and improve.
