Full-stack engineer

I build scalable full-stack systems, from robust backend services to high-quality React.js interfaces.

I design and develop secure, scalable applications across the stack — from APIs, microservices, event-driven services, and cloud infrastructure to performant React/Next.js interfaces. I focus on clean architecture, reliable systems, and seamless end-to-end experiences that deliver real business value.

Profile Snapshot

Role: Full-Stack Developer | Java / Spring Boot | React.js | Microservices
Location: Kénitra, Morocco
Status: Open to senior full-stack and backend-leaning roles, as well as high-impact freelance projects
Approach: Building distributed, production-grade systems with Java/Spring Boot microservices and React.js frontends.

About

Backend depth, frontend craft, full-stack confidence.

I focus on frontend product quality first, then reinforce it with practical full-stack delivery where it creates leverage.

I specialize in Java and Spring Boot microservices for distributed systems — designing and securing REST APIs, modeling event-driven flows with Kafka, and keeping services scalable and highly available in production.

I pair that with modern React.js and Next.js frontends, building responsive, reusable interfaces with TypeScript. I containerize and ship with Docker and Kubernetes, and keep systems observable with monitoring tools like Dynatrace and Kibana.

Working Principles

Design microservices for scalability, security, and high availability.
Build reusable systems instead of one-off implementations.
Keep architecture simple, explicit, and observable in production.
Balance engineering quality with business delivery speed.

Experience

Shipping at product scale with strong frontend ownership.

From enterprise teams to startup delivery, I focus on architecture that is maintainable, accessible, and ready for continuous iteration.
