Symfony Framework

Enterprise Application Development

My experience with Symfony is centered on developing large-scale, mission-critical applications for the Directorate General of Taxes (DJP). I utilized the full potential of the framework to build secure, high-performance, and maintainable systems.

A key project, SIKKA, the internal HR and payroll system, was built on Symfony, demonstrating its capability to handle complex business logic and sensitive data.

Microservices and APIs with API Platform

In the DJPConnect project, I heavily used Symfony alongside API Platform. This allowed for the rapid development of a comprehensive, standards-based REST and GraphQL API for the Identity and Access Management system. My work involved designing API resources, implementing custom business logic, and ensuring security and performance for a system handling authentication and authorization for the entire organization.

Key Competencies

• Symfony Core: Deep understanding of the framework's architecture, including the service container, event dispatcher, and kernel.
• API Platform: Expertise in building hypermedia-driven REST APIs, leveraging features like data validation, serialization, and automated documentation.
• Doctrine ORM: Proficient in data modeling and persistence using Doctrine, including complex queries and optimizations.
• Security: Implementing robust security measures using Symfony's security component, including authentication, authorization, and protection against common vulnerabilities.
• Performance Tuning: Identifying and resolving performance bottlenecks in Symfony applications.
