At Systango, I delivered end-to-end production features across Node.js, NestJS, PostgreSQL, MongoDB, Python, and React.js.
I design scalable REST APIs and business workflows, integrate third-party services, and own delivery from requirement analysis through deployment and post-release support. I improved average API response times by 20% through database and performance optimization while reducing UI-backend integration bugs through close frontend collaboration.
I also build practical products, including AI-Shield, a Chrome extension that redacts sensitive data before AI prompts are submitted, and ScanIT, an automated barcode attendance system that reduced manual tracking effort by over 80%.
