Summary
I am an experienced Senior Architect and Fullstack Developer focusing on React, TypeScript, and GraphQL (Apollo). My work centers on evolving and refactoring existing applications and integrating REST and GraphQL-based services into high-performance, scalable systems.
I put great emphasis on clean code, TDD, and high software quality. I have extensive experience in state management (Hooks, Context API, Redux/Zustand) and in designing and implementing modern software architectures.
With my expertise in testing (unit, integration, and end-to-end tests) and my solid skills in Git and code reviews, I ensure sustainable project development.
Additionally, I have a strong sense for UI/UX design, allowing me to balance technical and user-centered aspects. Clients benefit from my ability to make confident architecture decisions and support teams with experience and clear structures.
