Евгений Сологуб

I’ve built and migrated production web and mobile products for AppsTrain, Yoshi Parts, and freelance clients using React, Next.js, TypeScript, and React Native.

At Yoshi Parts, I migrated the global e-commerce marketplace from React CSR to Next.js SSR, improving SEO indexing and initial page-load speed. I also built an employee management and access-control portal from scratch and developed operations-panel features for orders, inventory, payments, pricing, and real-time error logs.

At AppsTrain, I delivered cross-platform releases on tight timelines, architected an offline-first state-management system with Jotai and persistent storage, and integrated Firebase, Sentry, REST/GraphQL APIs, and analytics SDKs. I maintained a 95%+ first-time approval rate through testing, code-splitting, and frontend quality standards.

My earlier business-analysis work helps me connect product requirements, UI/UX, and business goals. I also mentor developers, review code, and build modular UI systems that stay maintainable as products grow.
