View project ↗Senior Full Stack Engineer (Frontend-heavy) with 10+ years of experience designing, building, and scaling web applications, with experience in frontend (TypeScript, React, Angular) and backend (Node.js, Python, PostgreSQL). I've worked in demanding sectors like fintech and banking, high-traffic B2Cs, and B2B platforms with modules used by 10,000+ recurring users. I have strong skills translating business requirements into architectures like microfrontend and monolith, building REST and GraphQL APIs and modeling data, as well as designing responsive, accessible, UX/UI-focused interfaces, with prototyping in Figma. I approach every project with a product mindset, from understanding the business rules to how end users interact with each module. I have a track record of leading projects from planning to production, mentoring developers, and using AI tools (Claude Code, Cursor) to speed up delivery without sacrificing quality. My motto: teamwork is the key to success.
