Experience

Where I've worked

Software Engineer (R&D-1)

Keysight Technologies

July 2026 – PresentKolkata, WB
  • Working on the IxNetwork Infrastructure Team within Network Traffic Emulation division
  • Designing and maintaining high-performance network test and measurement software architectures

Software Engineer Intern

Keysight Technologies

Feb 2026 – June 2026Kolkata, WB
Internship
  • Developed an end-to-end gRPC-based service layer for real-time high-frequency telemetry collection
  • Achieved 92% lower latency and 7× smaller payloads compared to the legacy JSON path
  • Architected and evaluated three data transfer strategies (structured row-based, columnar, and raw memory BLOB) to evaluate trade-offs between data granularity, parsing overhead, and transmission efficiency
  • Implemented server-streaming RPC for real-time event notifications, replacing legacy polling-based approaches with true asynchronous push-based delivery with zero unnecessary network round-trips
