Amity Township, Pennsylvania, United States
Summary
👤
Senior🎓
Top SchoolDavid Parker is a Lead Developer with nine years of experience building and evolving Paid Memberships Pro, a widely used open-source WordPress membership platform and ecosystem of 60+ add-ons. He combines hands-on PHP backend work—especially payment gateway integrations and subscription handling—with product-level technical leadership, shaping the roadmap and steering major releases like PMPro 3.0. David regularly triages complex support escalations, turning real-world edge cases into robust, backward-compatible features that keep thousands of sites running smoothly. He’s driven measurable outcomes (e.g., improving sales through Sitewide Sales) and contributes directly to the core repo that powers recurring payments via Stripe, PayPal, Braintree, and more. Based in Amity Township, PA, he pairs a Haverford CS education and deep payment-domain expertise with an open-source mindset that prioritizes reliability, extensibility, and clear customer feedback loops. A detail that’s easy to miss: beyond feature work he’s improved billing error handling and tax support in checkout flows—small fixes that materially reduce revenue interruptions for users.
