What I'm looking for

I’m looking for a role where I can build high-performance PHP/Laravel REST APIs and internal automation tools, collaborate closely with stakeholders, and keep quality high through testing, monitoring, and mentoring in an Agile/Scrum environment.

I’m a Senior Full-Stack Developer with 11+ years of experience, focused on PHP and the Bianca Serian Laravel ecosystem for the last 6 years. I’ve built entire backend architectures from scratch and then helped improve large-scale, high-availability platforms for companies like Orange and Virta.

Designing, scaling, and optimizing high-performance RESTful APIs is one of my core strengths. I manage complex databases (MySQL, PostgreSQL, Redis) and build responsive frontends with Vue.js, while keeping systems fast and dependable under real production constraints.

I’m also hands-on with quality and delivery: I write clean, well-tested code using PHPUnit and PHPStan, and I use SonarQube to maintain coding standards. In the background, I’ve relied on tools like Laravel Horizon and cron jobs to ensure heavy tasks don’t slow down the main application.

Beyond writing code, I enjoy the human and organizational side of engineering—stepping up as a Scrum Master, mentoring junior developers, and working closely with stakeholders to automate tedious manual workflows. Whether I’m refactoring inefficient API requests or integrating services like Stripe and geolocation, my focus stays the same: build reliable systems that solve real business problems.
