About

I build the backend and infrastructure a 4G/5G mobile network actually runs on, not the app sitting on top of it. For the past two and a half years at Highway9 Networks, I've worked on a multi-cloud edge platform spanning GCP and Azure. I automated Azure VM provisioning end to end, with Ansible roles and a managed image pipeline wired into Jenkins, now running across 100+ customer sites. I replaced base64-encoded Kubernetes Secrets with keyless access through Google Secret Manager and Workload Identity Federation across 20+ multi-tenant GKE workloads. And when we moved monitoring from Prometheus to VictoriaMetrics, I wrote vmctl, a resumable backfill tool that chunked a year of metrics history into 24-hour windows it could safely rerun without duplicating data. Outside of work I build systems from scratch, mostly because resume bullets don't scratch that itch. A routing engine in C, using a longest-prefix-match trie and Dijkstra's algorithm to resolve next hops. An HTTP/1.1 server in Python, built directly over raw TCP sockets instead of a framework. And a Go reverse proxy and load balancer that holds 10k+ requests per second under load, with its own retry classification and health checks. Three layers of the same stack, each one built to see what the frameworks usually hide. Currently looking at backend and infrastructure roles in India, primarily with Go. Open to other stacks for the right problem.
