At Alfa Ecosystem, I develop core features for a classifieds and auctions marketplace, including listings, search, favorites, user accounts, and real-time buyer–seller chat. I improved real-user LCP from 3.6s to 1.2s and raised the Lighthouse score from 55 to 79.

I worked on technical SEO for filter pages, and organic traffic grew by 25%. I also migrated feed and lot pages to Next.js Cache Components and Partial Prerendering, reducing API requests and RPS by 35%.

Earlier, at Itransition, I built a questionnaire app and developed its Express.js API. My project experience at GeekBrains includes a React hotel management system and responsive e-commerce interfaces.
