What I'm looking for

I am seeking frontend roles focused on React/TypeScript, performance and scalable architectures, with collaborative teams that value testing, measurable impact, and professional growth.

I am a frontend developer with 5+ years building scalable SaaS applications using React, TypeScript, and Redux Toolkit. I focus on performance optimization, modern frontend architecture (FSD, SOLID), robust testing (Jest, RTL, Playwright) and reliable offline and real-time features.

My notable achievements include creating an offline-first sync system with Service Workers and IndexedDB, integrating BIM with WBS for 4D visualization, and delivering real-time synchronization for 50,000+ concurrent users. I prioritize measurable impact—faster rendering, higher sync success rates, and reduced coordination time—while maintaining high code quality and test coverage.
