Ali Saidi Elhassani

I help companies design, build, and modernize robust backend systems and web applications using Java, Spring Boot, and microservices architecture. From scalable REST APIs to full enterprise platforms, I deliver clean, maintainable, production-grade software that teams can build on.

I've worked with established firms such as TUI and CGI, delivering software in demanding, professional environments with high standards for code quality, architecture, and collaboration. That experience means I integrate smoothly into existing teams, follow best practices, and can be trusted with complex, business-critical systems.

What makes me stand out:

Strong backend expertise in Java and Spring Boot — REST APIs, business logic, security, and data access.

Solid command of microservices architecture: service decomposition, inter-service communication, and scalable, resilient system design.

Full-stack capability with modern frontend frameworks — Angular, React, and Vue — so I can own features end to end.

Experience delivering for large organizations like TUI and CGI, where reliability and clean architecture matter.

Projects and deliverables I typically handle:

Backend APIs and services with Java / Spring Boot

Microservices architecture design and implementation

Migration of monoliths toward microservices

Full-stack web applications (Spring Boot + Angular / React / Vue)

REST API design, integration, and documentation

Database design and integration (SQL / PostgreSQL)

Code reviews, refactoring, and technical improvements

If you need a reliable senior developer who can architect solid backends, build modern frontends, and deliver to enterprise standards — let's talk.
