Fintech Backend & Payment Infrastructure DevelopmentAyaz Ashraf
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.
