At an e-commerce marketplace, I architect backend infrastructure for marketplace operations serving 50,000+ active users. I engineered an order-processing pipeline that reduced API response times by 45% through Redis caching and PostgreSQL query optimization.
I also designed a fault-tolerant payment integration layer with retry mechanisms and idempotency guarantees, achieving 99.9% transaction reliability. I set backend architecture patterns and CI/CD standards that reduced release cycle time by 50%.
At CompassWay Fintech Solutions, I developed backend systems for digital financial products and payment processing. I built a compliance service for secure regulatory submissions and an automated payment system with recovery across failure scenarios.
At Inforce, I developed a real-time token trading platform for 3,000+ trading pairs across decentralized networks. I built a WebSocket market-data pipeline and a smart-contract execution pipeline for DEX integrations.
