Project Lead · 10+ Years · Available for Select Contract Engagements
Senior Go engineer specialising in network automation, SDN orchestration, and telecom systems — 10 years across 5G core, ORAN, and carrier IP transport, with a track record across Rebaca, Spica, and Polaris Networks. Strong in system design, delivery leadership, and turning complex requirements into reliable code.
About
Project Lead and senior engineer with 10+ years shipping backend systems, cloud platforms, and high-performance network automation software — in enterprise teams and production side projects alike.
I'm a results-driven software engineer and Project Lead with 10+ years building software that holds up in production. I'm currently at Persistent Systems, leading intent-driven service orchestration for a carrier-grade SDN controller platform — cloud orchestration and automation for enterprise IP transport networks. Previously, I shipped 5G and telecom platforms at Rebaca, Spica, and Polaris Networks. In my spare time, I design and ship full-stack backend systems as personal, part-time projects.
My core stack is Golang, C/C++, and Python, applied across microservices, protocol engineering, Docker/Kubernetes deployments, and network automation. I thrive on breaking down complex designs and delivering maintainable solutions — whether that's gRPC backends, ORAN integrations, or a production-ready app from idea to launch.
"Surya is very hard working and a good programmer. I always felt comfortable when he is there in the team. He is particularly very good when it requires analysis of the new design and implementing the same with new technologies and languages."Soumya Pal — Colleague & recommender on LinkedIn
