Platform Development
I design and ship the core systems ministries, credit unions, and growing companies run every day: registries, recovery workflows, loan ops, dashboards, and admin portals. Production software with audit trails, roles, and real data volumes, not slide-deck prototypes. That work is backed by deep PHP engineering, including Zend Certified Engineer credentials.
