Background Story: Unveiling My Journey

My story

I am a full-stack developer with hands-on experience building end-to-end web products, from scalable backends to interactive frontends. On the backend, I work mainly with Node.js, NestJS, and Postgres, and I have built GraphQL Federation services at Ouedkniss and backend systems for Hader and Click2Secure using Prisma and TypeORM. I also work on the frontend with React, bridging the gap between clean APIs and polished user interfaces. I enjoy designing maintainable software with Vertical Slice Architecture, Clean Architecture, and Domain-Driven Design, always keeping an eye on clear boundaries, scalability, and data integrity. I thrive in fast-paced environments where I can take ownership, collaborate closely, and help build reliable, high-impact products.
