Lviv, Ukraine

I build apps and custom solutions for merchants who need things that work — not dashboards full of features nobody uses. My approach: understand the problem deeply, build the simplest thing that solves it completely, ship fast, iterate on real feedback.

AI is deeply integrated into my workflow — I use Claude, GPT, and local LLMs daily for development, code review, and rapid prototyping. I'm exploring PyTorch for neural network fundamentals and building AI-powered features into my apps.

Outside of Shopify, I'm tinkering with embedded development (C/Rust on PlatformIO) and building sorta.market as a personal project.
