About

As a Software Engineer with hands-on experience in building scalable backend systems, I've consistently focused on delivering performance-driven solutions in fast-paced environments. At Snapmint, I led impactful backend optimizations—migrating services from Express to Fastify for better routing performance, replacing Winston with Pino to implement an asynchronous, centralized logging system across microservices, and transitioning a critical service from REST APIs to Kafka-based communication to bolster inter-service reliability at scale. I also engineered Redis-based distributed caching, significantly cutting API latency for over 2M+ users, and diagnosed a key production issue by curbing unnecessary database pulls from 100+ to just 1 per month. Additionally, I developed comprehensive unit tests using Mocha, Chai, and Sinon, increasing test coverage and reinforcing system reliability. Previously, at Recruizo, I architected and developed a high-performance coding contest platform using TypeScript, Next.js, and MongoDB—boosting system efficiency by 40% and reducing response time by 30%. I also integrated AWS S3 for secure and scalable test case storage, reinforcing my understanding of cloud infrastructure. I'm in my final semester of completing my B.Tech from Delhi Technological University and am currently seeking full-time opportunities. With a strong foundation in Data Structures and Algorithms, Operating Systems, DBMS, and OOP—and hands-on experience in building scalable systems and microservices—I'm passionate about solving real-world problems through efficient software design and development.

  • Migrated backend services from Express.js to Fastify, improving routing performance and reducing overhead under high concurrency conditions.
  • Implemented an asynchronous, centralized logging utility (logger-v2) using Pino, replacing Winston to ensure consistent, low-latency logging across all microservices.
  • Transitioned Credit Bureau Service from REST API to Kafka-based communication, increasing system reliability, scalability, and fault tolerance under load.
  • Optimized Redis-based distributed caching, reducing API latency for 2M+ users from 150–100ms to 10–14ms by replacing traditional LRU caching.
  • Resolved critical production bottleneck by minimizing unauthorized DB pulls from 100+ to 1 per 30-day cycle, significantly improving database efficiency and system integrity.
  • Wrote comprehensive unit tests using Mocha, Chai, and Sinon, increasing code coverage and reliability across key modules.
  • Worked closely with senior developers in designing scalable microservices architecture, applying best practices in logging, caching, and API design.
  • Collaborated with cross-functional teams to monitor system metrics, identify issues early, and implement performance improvements across multiple backend services.
