Software Engineer
Hi, I'm Aleksei 👋
I'm a software engineer (React.js, Node.js & Go) with a focus on creating and designing exceptional digital experiences that are fast, accessible, visually appealing, and responsive.
Even though I have been creating web applications for over 10 years, I still love it as if it was something new.

A little bit about me
I'm a developer who genuinely loves what he does. Over 10 years in and I still get that spark when starting a new project or solving a tricky problem. I work primarily with React, Node.js, and Go, building things that are fast, look great, and actually work well for real people.
When I'm not coding, you'll probably find me exploring new tools and technologies, tinkering with side projects, or traveling the world. I've visited 20+ countries and counting. I'm a firm believer that the best developers are the ones who never stop being curious.
I care a lot about the details: clean code, smooth animations, pixel-perfect layouts. The kind of stuff users might not consciously notice, but definitely feel. That's what makes the difference between something good and something great.
