Senior Software Engineer in Vilnius, Lithuania


Senior Software Engineer who enjoys optimizing development workflows and minimizing boilerplate. I never stop learning and enjoy sharing my experience and insight with others.

I am an expert in TypeScript/JavaScript, Swift, and Python. I also use Go, C#, and Rust extensively in my side projects, but not professionally.

On the tooling side, specialize in Full-Stack Development, UX/UI Design, Machine Learning, and Game Development.




2019 — 2020
St. Andrews, UK

After dabbling in simple neural network design I decided to join this course to learn more about AI in a more structured way. This experience taught me a lot about AI and made me able to research and create my own AI with the most suitable approach.

2016 — 2019
Liverpool, UK

This was a very dense learning experience. I learned the full spectrum of things about computers, from low-level things like designing my own silicon chip and making my own audio amplifier to high-level things like data structures, game theory, neural networks, etc.

2012 — 2016

4-year art school study where I learned most of I know about sculpture, composition, painting, sketching, photography, design and art history.

Side Projects


Inspired by a meme, I created this random excuse generator which generated an excuse for not attending something via 3 part structure. Try it out to get the reason for not attending that party you don't want to go to!


React hook that simplifies management of GDPR consent for JavaScript/TypeScript developers. This is something that I needed myself, and from the attention it's getting I see that I'm not alone. It's still in development, but with v1 release, it will cover all possible developer needs, including support for Vue, Svelte, and others.


This swift package allows adding a nice-looking tooltip to your SwiftUI app with one line of code. Can't come up with a simpler solution!


A compiler that transforms SVG code into SwiftUI Shape structure. It allows converting SVG icons to Swift code to display in a SwiftUI app.


This app lets users create polyrhythms with ease while also functioning as a regular metronome. It features an integrated tuner for the user to have the only two things they need to practice.



A software service company I created for bigger projects.
