I’ve been working with backend development for 10 years, mainly using PHP and Laravel. I focus on delivering value to end users while keeping performance, stability, and continuous code evolution at the center of my work.

In my current role as a Backend Developer, I work on the travel booking flow using PHP 8 and Hyperf. I develop and maintain critical microservices, implement new features, refactor legacy code, and improve test coverage across the squad’s services—moving from approximately 50% to +90%—while reducing latency in essential booking flow components.

Previously, I supported retail energy distribution systems, including invoice collection services, authenticated user areas, energy consumption calculation, and billing. I also integrated new partners, refactored core systems, and improved mass processing and reporting performance, with a strong emphasis on maintainable architecture and reliable delivery.

I’ve also worked across payments and marketplaces: contributing to a QR-code payment microservice, integrating major providers to expand market coverage, and strengthening performance, resilience, structured logging, documentation, automated runbooks, and integration testing. Earlier, I helped refactor a marketplace from Zend Framework 1 to Laravel and supported full-cycle development, from architecture to production deployment, and I’ve built RESTful APIs and supporting frontend elements using PHP, HTML5, Bootstrap, and JavaScript.
