Hi, I'm Asim — A Software Engineer.

• Engineered a robust payment processing system using Node.js and Razorpay, implementing HMAC-SHA256 signature verification to validate and mitigate man-in-the-middle (MITM) attacks.

• Implemented a real-time recommendation system with Voyage AI and ConvexDB to show relevant content to users like YouTube.

• Built a Lambda to automatically remove unused EBS snapshots, reducing AWS storage costs.

• Optimized API performance by integrating Redis caching with Node.js, reducing response times from 7–8 seconds to under 10 milliseconds for frequently accessed endpoints, significantly lowering backend load.

• Used the Sidecar pattern to add logging and authentication without changing the main backend code, improving scalability, simplifying updates, and enhancing overall maintainability.

• Refactored code using SonarQube, Dockerized microservices for consistency, and integrated Redis and Kafka to enhance caching and event-driven communication.

• Used TanStack Query for API data fetching and Zod to input validation, improving performance and reliability
