Full-Stack Developer with over 11 years of experience in PHP, focusing on the Laravel ecosystem for the last 6 years. My career has taken me from building the entire backend architecture for a ride-sharing app from scratch, to improving 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, alongside managing complex databases (MySQL, PostgreSQL, Redis) and building responsive frontends with Vue.js. Beyond writing clean and well-tested code (PHPUnit, PHPStan), I enjoy the human and organizational side of software engineering. Whether it's stepping up as a Scrum Master, mentoring junior developers, or working closely with stakeholders to automate tedious manual workflows, I focus on building reliable systems that solve real business problems.
