Is your payment infrastructure costing you customers, revenue, or sleep? I build payment systems that don't just work — they scale, recover automatically, and turn checkout friction into conversion. With 10+ years in FinTech, I've architected payment infrastructure for startups and enterprises alike — processing $20M+ in transactions across 200+ apps globally. Whether you need a Stripe integration built right the first time, a subscription engine that survives edge cases, or a multi-gateway setup that cuts processing costs — I've done it, and I have the numbers to prove it. What I Deliver - • Payment Gateway Integration — Stripe, Stripe Connect, PayPal, Braintree, and custom multi-gateway architectures built for reliability and speed • Subscription & Recurring Billing — Smart dunning logic, partial payments, proration, multi-invoice handling, and churn reduction workflows • Fraud Prevention & Compliance — PCI-DSS, 3D Secure, SCA, tokenization — security that protects your business without killing conversion • Mobile & In-App Purchases — Apple App Store, Google Play Billing, and RevenueCat integrations with cross-platform sync and policy compliance • Webhooks & Automation — Real-time failure handling, automated retries, chargeback management, and event-driven revenue recovery • Cost Optimization — Reduced one client's monthly processing costs from $160K → $50K through gateway routing and fee structuring • App Store Payment Compliance — Payment flows built to pass Google and Apple review — no rejections, no rework Results I've Driven 1.
