Back to original languageAbout Haroun
Full-Stack Developer specializing in Spring Boot/Angular, I delivered a complete enterprise CRM to production in 4 months, as the sole developer, for a Tunisian energy company — replacing a legacy system across 8 modules and 15+ relational tables.
What sets me apart: I also set up and operated a B2B import-export company across 5 countries. I understand deadlines and business stakes, and I deliver without follow-up.
What I do:
- Secure REST APIs (Spring Boot, Spring Security, JWT)
- Angular/React frontends with real-time integration
- MySQL database design
- Docker deployment
- Integration of AI tools into business applications
