Make important WordPress changes with less risk

I’m a senior WordPress and WooCommerce developer with 20+ years of experience across PHP, APIs, performance, hosting, and technical SEO.

Layered technical architecture representing code, operations, infrastructure, and search

When teams usually bring me in

  • A live site has become hard to change

    Old code, plugin conflicts, or fragile workflows make every update feel risky.

  • Performance or SEO is holding the site back

    Slow pages, technical issues, or messy foundations are costing trust and visibility.

  • A project needs senior ownership

    The work needs someone who can diagnose the issue, explain the plan, and carry it through.

Why teams trust me with production work

  • 20+ years working on real websites with real business pressure.

  • Careful with legacy code, plugins, custom workflows, and WooCommerce complexity.

  • I find the cause before changing code, so fixes are based on evidence—not guesses.
