Software Engineer

Cisco

Bengaluru, India

I write software in C at Cisco. Before that, 4 years at Tejas Networks on the software that manages 4G and 5G RAN platforms — the unglamorous layer that keeps a hundred thousand nodes reachable.

Focus

  • Networking & systems. Production software for 4G and 5G RAN platforms — IPv6 migration, IPC APIs, and device state machines running across 100k+ nodes.
  • Low-level engineering. C/C++ with an eye on memory safety and concurrency. 50+ production bugs closed with GDB, Valgrind, tcpdump, and core dumps.
  • Design & mentorship. Reviewed 10+ system designs and mentored junior engineers, with a bias toward architecture that stays legible under load.

Senior Engineer

—

  • Designed network management components for 4G and 5G RAN platforms.
  • Migrated core networking services to IPv6, enabling dual-stack support across production elements.
  • Built a network device state machine with live component tracking, cutting incident resolution time by 50%.
  • Designed IPC APIs using message queues and UDP sockets for distributed network element communication.
  • Optimized config processing with in-memory hash maps, improving lookup performance and reducing latency.
  • Reduced memory leaks and crashes in network services using smart pointer-based C++ designs.
  • Reviewed 10+ system designs and mentored junior engineers on software best practices.

Engineer

—

  • Built database-backed node lifecycle workflows for provisioning, reducing manual operations by 60%.
  • Enabled cross-node config recovery via upload and restore features, cutting manual effort by 50%.
  • Fixed 50+ memory safety and concurrency bugs in production software using GDB.
  • Hardened system startup and shutdown sequences, reducing restart time and improving availability.
  • Refactored legacy C networking modules into modern C++ using OOP and design patterns.
  • Automated CI/CD build, packaging, and validation pipelines, cutting release effort by 30%.
