I built LinkHub, a Java and Spring Boot microservices platform provisioned with Terraform on AWS. It uses PostgreSQL and Redis for link redirection, with ArgoCD GitOps delivery and Prometheus/Grafana monitoring.
For my Go reverse proxy and API gateway, I implemented round-robin load balancing, a three-state circuit breaker, and a per-IP token-bucket rate limiter. I also instrumented Prometheus metrics and shipped a smaller distroless image.
I built a Kubernetes operator with Kubebuilder and controller-runtime to reconcile a ProxyService custom resource with Deployments, Services, and ConfigMaps. I wrote unit and integration tests using setup-envtest.
At Tejas Networks, I analyzed EPC and eNodeB protocol logs to identify throughput degradation and latency spikes. I automated metric extraction and built observability dashboards to reduce manual triage time for senior engineers.
