I’m a Frontend Developer with 5+ years of experience building complex B2B and internal systems, with a focus on data-heavy interfaces and high performance. At MTS Digital, I develop a monitoring platform for 10,000+ cellular base stations, including an interactive Yandex Maps-based network map, telecom quality metrics, and a Kibana-like logging service.

I’m strong in React and TypeScript, Feature-Sliced Design, and frontend architecture. I’ve delivered major performance wins by introducing render optimizations (debounce, memoization, batching) and reducing analysis and freeze issues—like cutting problem-area analysis from 3 hours to 10–15 minutes.

I also build reliable testing and release workflows. I migrated e2e testing to Playwright, stabilized tests, and optimized CI runs (parallelization and isolation), while improving team releases by introducing GitFlow and adding automated CHANGELOG with Husky.

Before MTS Digital, at SmartWay I worked on a B2B business travel platform and an internal document workflow service, integrating Editor.js and QR flows (zxing-qr), implementing anti-bot protections, and setting up an automated testing pipeline with Docker and CI/CD. I enjoy proactive engineering improvements—like reducing new developer onboarding from 1 month to 2 weeks.
