    Bio

    I’m a software engineer with 10+ years of experience building and scaling WordPress products used by hundreds of thousands of sites.

    I’ve contributed extensively to plugins like The Events Calendar and Event Tickets, working on everything from ticketing systems and payment integrations to performance optimization and large-scale architecture. My work has focused on building reliable, maintainable systems that perform well across diverse WordPress environments.

    Over the years, I’ve:

    Helped scale products from tens of thousands to hundreds of thousands of active installs
    Improved performance through caching, query optimization, and system-level enhancements
    Built and maintained integrations with platforms like WooCommerce, Stripe, and PayPal
    Worked closely with support and QA teams to resolve real-world issues and improve user experience

    I enjoy working on complex systems where backward compatibility, extensibility, and performance matter. Recently, I’ve also been exploring AI-assisted development workflows and tooling to improve engineering productivity and code quality.

    I’m comfortable working across the full stack (PHP, JavaScript/TypeScript, React) and collaborating in remote, distributed teams.

    Interests

    When I’m not coding, I’m usually gaming or catching up on films — the perfect balance of competition and creativity.

    WordPress Origin Story

    My programming journey began during my university days, learning C and C++ as a Computer Science student. That foundation eventually led me to PHP — a language I quickly grew comfortable with. And then came WordPress.

    Discovering WordPress was a turning point. It combined the flexibility of PHP with the excitement of building real products that people could use. What started as a fun experiment soon became a passion.

    I began freelancing in 2012, taking on small WordPress projects just for the joy of creating. Over time, that hobby evolved into a full-fledged career — shaping the path I continue to follow today in the world of WordPress development.
