Backend Software Engineer
I am a Backend Software Engineer with 3 years of experience at the Center for Development of Telematics. I successfully redesigned a REST API pipeline to eliminate a blocking I/O bottleneck, increasing throughput from 500 to 3,000 requests per second while significantly reducing CPU overhead. I am deepening my expertise as a Backend Developer, focusing on performance engineering to create even more efficient and scalable systems.
Developed a REST API service for URL shortening, handling over 10,000 requests/sec using Go and Gorilla Mux. Implemented a Redis caching layer, reducing database load by 70% and average response time to less than 5ms. Designed a click analytics pipeline to track geo, device, and referrer data, stored in PostgreSQL. Containerized the application using Docker and developed a load test suite with k6 to benchmark performance.
View Source CodeDeveloped a Go-based log and PCAP analyzer, achieving a 80%+ reduction in troubleshooting time. Enhanced log search capabilities, decreasing debugging time from hours to minutes.

Identified a blocking I/O bottleneck in the REST API pipeline, redesigned it as a non-blocking state machine, achieving 3,000 req/sec while reducing CPU overhead. Diagnosed lock contention in the task scheduler, replaced the shared-queue model with a work-stealing scheduler. Designed a token bucket rate limiter, replaced polling-based watchdog timers with timer-driven callbacks, and profiled memory leaks with Valgrind and pprof.
Jul 2023 – Aug 2023
Re-architected inter-process communication from TCP sockets to Unix Domain Sockets, achieving a 20% reduction in IPC overhead. Implemented packet-level latency instrumentation for performance analysis.
Oct 2022 – May 2023
Optimized RESTful APIs and SQL queries, achieving a 15% reduction in response times. Developed a secure KYC document upload pipeline using AWS S3. Shipped 5+ production features, collaborating across backend, frontend, and product teams in an agile workflow.
