Role
Sole Developer & Architect
A funded startup needed to launch a payment processing platform quickly to start validating their business model with real customers. They had a tight runway and needed to move fast without compromising on security or scalability.
The Challenge
- •Launch a fully functional payment platform in under 2 months
- •Handle sensitive financial data with bank-grade security
- •Build for scale from day one—rewriting later wasn't an option
- •Integrate with Stripe for payment processing and compliance
- •Provide real-time transaction reporting for both merchants and admins
The Solution
I designed and built a complete payment processing system with a focus on security, reliability, and speed to market.
Secure Payment Flow
PCI-compliant payment processing using Stripe, with tokenization to ensure sensitive card data never touches our servers.
Real-Time Dashboard
Live transaction monitoring, revenue analytics, and reporting for merchants to track their business performance.
Multi-Merchant Support
Architecture supporting multiple merchants with isolated data, individual configurations, and separate reporting.
Webhook Processing
Reliable event handling for payment confirmations, refunds, disputes, and subscription lifecycle events.
Admin Tools
Internal dashboard for customer support, transaction investigation, and platform analytics.
