Full-Stack Software Engineer

Nov. 2025 – PresentTetouan, Morocco
💡 Core Impact: Engineered high-throughput enterprise Invoicing Microservice for the KAFA'AT EMS platform.
Engineered a full-stack Invoicing Microservice from the ground up for the enterprise KAFA'AT EMS platform utilizing Java / Spring Boot and Angular (PrimeNG).
Designed and implemented complex financial computation engines, custom worktime overrides, automated billing cycles, and dynamic taxation calculation (TJM).
Engineered an automated high-throughput PDF compilation pipeline using JasperReports capable of generating multi-page financial statements with zero memory leaks.
Secured all RESTful API endpoints via stateless JWT authentication, granular Role-Based Access Control (RBAC), and method-level security.
Maintained 95%+ test coverage through JUnit and Mockito unit/integration test suites within an Agile/Scrum workflow.
Architectural Decisions:
• Microservice separation decoupling invoice calculation from core EMS
• Asynchronous JasperReports PDF generation worker with Redis cache
• ACID transactional guarantees for billing balance consistency
