Senior Consultant at Altezzasys Pvt Ltd building Go operators and Kubernetes CRDs for cloud-native platform automation.

At Altezzasys Pvt Ltd, I’m working on Go-based Kubernetes operators for application containerization and automation. I’m developing CRDs and reconciliation logic to manage application configuration, deployments, retries, recovery, and status.

At Hewlett Packard Enterprise, I led the modernization of the Integrated HSS / HLR-HSS platform from a monolith to Golang and Kubernetes microservices. I built a custom Kubernetes Operator and implemented CRDs, controller reconciliation, webhook validations, and recovery workflows.

Across telecom, Linux systems, and platform engineering work, I’ve developed backend features for messaging, billing, and phone simulation systems. I’ve also improved platform reliability with health probes, auto-healing, structured logging, and Prometheus metrics.
