Dax Castellon working in a technical setup

The best deployments are the ones nobody notices

I’m a senior WordPress and WooCommerce developer with 20+ years of experience across PHP, APIs, performance, hosting, and technical SEO—helping teams deliver reliable websites, solve complex technical problems, and make changes with confidence.

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

Where I bring the most value

  • Confident changes to live websites

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

  • Helping your website perform at its best

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

  • Senior expertise when it matters most

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

Keep your team focused

I will handle the complex development.

API integrations

Product and order data should move between systems without manual cleanup.

Technical SEO

Search issues in your templates need code fixes, not one-off edits.

Astro development

Fast content sites with less JavaScript and a structure that is easy to update.

Why teams trust me with production work

  • Proven where it matters

    Over 20 years building and maintaining websites that support real businesses, real customers, and real revenue.

  • Safe hands for complex systems

    Experienced with legacy code, custom integrations, WordPress, WooCommerce, and production environments where every change matters.

  • Evidence over assumptions

    I identify the root cause before writing code, so every fix is based on evidence—not guesswork.
