Who I am

I'm a Senior Frontend Developer based in Bishkek, Kyrgyzstan, with a passion for creating fast, accessible, and beautiful web experiences. Over the past 10+ years, I've evolved from crafting pixel-perfect layouts to architecting complex frontend systems and custom frameworks.

What drives me most is solving interesting technical challenges and improving developer experience. Whether it's building a custom JavaScript framework, migrating servers to improve performance, or setting up robust testing pipelines – I love diving deep into problems and finding elegant solutions.

What I'm working on

Currently, I'm focused on modern web technologies like Astro.js, Vue 3, and Fastify for server-side rendering. I'm particularly interested in performance optimization, web accessibility, and creating developer-friendly tooling.

I'm also the author of @zoxon/nux – a lightweight JavaScript framework that I created for component lifecycle management. It's been a fun project to work on and has taught me a lot about framework design and TypeScript.

Beyond code

Outside of work, I am a gamer with a passion for video games that offer either compelling gameplay or strong narratives and stories.

Additionally, I enjoy working with my hands, whether it's fixing something, or crafting DIY projects. I find great joy in creating and fixing things, which allows me to express my creativity and problem-solving skills in a tangible way. I also love spending time with my wife and our children Kirill and Alice.

I'm open to connecting with developers and collaborating on frontend and fullstack projects.
