Frontend Developer with 2+ years building scalable React CRM/SaaS interfaces.
UkraineWhat I'm looking for
I’m a Frontend Developer with 2+ years of commercial experience building scalable CRM and SaaS interfaces using React, TypeScript, and Redux Toolkit. I’ve implemented RBAC and permission management across 5+ user roles, built complex multi-step forms with React Hook Form, and integrated REST APIs with Axios for reliable async data flows. I also focus on performance—developing 10,000+ row data tables and using code splitting and memoization to reduce render time and initial bundle size.
I’m comfortable delivering both greenfield features and legacy refactoring, including reducing ~25% duplicated code and cutting production incidents by ~20%. I enjoy collaborating in 2-week sprint cycles with backend developers and designers, and I actively use AI tools (GitHub Copilot, Claude, ChatGPT) to accelerate delivery, improve code review quality, and draft technical documentation. I value clean, maintainable UI architecture with strong developer experience and measurable outcomes.
