I've built and maintained WordPress solutions for IIG Global, Hyperion Tech, Impltech, and Utec, including a commercial AI-powered SaaS plugin with custom database architecture, REST API integrations, and wp.org submission preparation.

At Hyperion Tech, I developed plugins and themes for 40+ US production sites, built SportsDataIO and Customer.io integrations that increased engagement by 12% and loyal visitors by 8%, and improved a high-traffic Japan site to support 20% organic traffic growth. I work across PHP, MySQL, performance optimization, technical SEO, deployment, code review, and mentoring, and use Claude Code for agentic development workflows.
