Full-stack JS, PHP, MySQL, API development and integration

Your PHP system works, but it’s slow, fragile, and hard to change. I’m a full-stack PHP developer with 20 years of experience in legacy code, REST APIs, and payment integrations. I fix what’s broken, speed up what’s slow, and add new features without breaking production. I build and connect PHP and JavaScript applications with APIs, payment gateways like Stripe and PayPal, and automated workflows. You get reliable integrations, fewer manual tasks, and payments that just work.
