About

Hi — I'm Maksym. I build web products.

I'm Maksym — a software engineer with 4+ years in React, TypeScript and Next.js. I build web products end-to-end — interfaces, APIs, databases, deployment — the kind of software where performance, state architecture and clean code are the product, not the packaging.

Since 2022 I've grown from engineer to tech lead — helping teammates through reviews, owning features end-to-end and shipping tools used at high traffic. I optimise what's slow, debug what's broken with DevTools and Network traces, and lean on AI tooling to deliver faster without cutting corners.

Off the keyboard my pattern is the same: pick a hard problem, iterate until it clicks. Whether the summit is a leaderboard place or a mountain top, the loop is what I chase — the specifics live further down in Achievements.

Philosophy

My loop is simple: build it, put it in front of people, fix what confuses them — repeat until it feels obvious.
