Senior Fullstack Engineer | JavaScript & TypeScript Expert | 20+ Years of Experience
Senior Fullstack Engineer with over 20 years of experience, with a primary focus on modern Frontend development and high-performance UI architecture. Expert in building scalable web ecosystems using React 19 and Vue 3, I specialize in creating seamless user experiences by bridging the gap between sophisticated backend infrastructures and intuitive interfaces.
My expertise includes architecting unified API strategies with GraphQL (Apollo Federation), orchestrating mission-critical workflows with Temporal.io, and implementing robust state management patterns using TanStack Query. I have a deep background in multi-tenant architecture ande-commerce systems, with a proven track record of modernizing legacy platforms and leading technical evolutions that deliver immediate business value.
