Back to original languageAbout Fahrettin
I am an experienced Senior Architect and Fullstack Developer with a focus on React, TypeScript, and GraphQL (Apollo). My focus is on the further development and refactoring of existing applications as well as the integration of REST and GraphQL-based services into performant, scalable systems.
I place particular value on Clean Code, TDD, and high software quality. I have extensive experience in state management (Hooks, Context API, Redux/Zustand) as well as in the conception and implementation of modern software architectures.
Thanks to my expertise in testing (unit, integration, and end-to-end tests) and my confident work with Git and code reviews, I ensure the sustainable further development of projects.
Furthermore, I have a strong sense for UI/UX design, which allows me to balance both technical and user-centric aspects. Clients benefit from my ability to make architectural decisions with confidence and to support teams through experience and clear structures.
