I design and implement secure, scalable backend systems focused on revenue and payments.

From payment gateway integrations to subscription logic and webhook automation, I build the infrastructure that powers SaaS platforms, marketplaces, and fintech-enabled businesses.

I specialize in:

• Stripe, PayPal, Paddle, Authorize.net, KNET integrations • Subscription billing & recurring payment systems • Webhook handling & event-driven architecture • Multi-gateway fallback systems • Secure transaction workflows • Payment reconciliation logic • Custom admin dashboards for revenue tracking • API-first backend development (PHP, Python)

Whether you’re launching a SaaS product, scaling subscriptions, or fixing a fragile payment system, I ensure your backend is secure, reliable, and built for growth.

Revenue systems must be engineered correctly the first time.
