About

I’m an Associate MLOps / Platform Engineer with 2+ years of hands-on experience working on on-premises Kubernetes (RKE2) clusters and distributed storage platforms supporting national-scale financial systems. My work focuses on Kubernetes platform operations, distributed storage, and infrastructure automation, with real production exposure across cluster deployment, upgrades, and node-level troubleshooting. What I work on: • On-prem Kubernetes (RKE2) cluster deployment and operations • Kubernetes Networking (CNI) and node-level troubleshooting • Rook Ceph (RBD & RGW) and MinIO for block and object storage • Terraform & Ansible for infrastructure and operational automation • GitOps (Argo CD) and CI/CD pipelines (Jenkins) • Monitoring & observability using Prometheus and Grafana • Incident response, RCA, and disaster recovery I’ve contributed to a 4 PiB production data migration from MinIO to Rook Ceph, achieving 30% throughput improvement and 40% cost optimization, while supporting platforms processing 650M+ daily UPI transactions. I also author public technical blogs on Rook Ceph deployment and disaster recovery, published on NPCI’s official website and shared on LinkedIn and X. 📫 Let’s connect — especially if you’re working on large-scale Kubernetes, storage, or SRE challenges!

Associate MLOps Engineer

Oct 2024 – Present · 1 yr 7 mos · Hyderabad, Telangana, India · On-site

As a Site Reliability Engineer (SRE) at the National Payments Corporation of India (NPCI), I manage and optimize the on-premises Kubernetes-based infrastructure that powers the nation’s digital payment ecosystem. My work ensures the availability, reliability, and scalability of critical systems that process hundreds of millions of UPI transactions daily.
Key Responsibilities & Achievements:
Engineered and managed Rook Ceph clusters (RBD & Object Store) for production workloads, ensuring data durability, performance, and seamless scalability.
Designed a dual-tenant Ceph architecture — RBD pools supporting Kubernetes Persistent Volumes (PVs) for Superset, Trino, and Spark, and Object Store (S3) powering analytical and ML pipelines.
Proved the scalability and resilience of NPCI’s on-prem infrastructure, enabling UPI to process over 650M+ daily transactions (surpassing Visa) through efficient Ceph capacity planning and I/O optimization.
Automated deployments and upgrades using ArgoCD (GitOps) and Ansible, ensuring repeatable, version-controlled operations.
Enhanced observability by integrating Prometheus, Grafana, enabling proactive monitoring and faster incident resolution.
Executed disaster recovery procedures to restore production Ceph after namespace deletion incidents with zero data loss.
Collaborated with product, data, and security teams to optimize infrastructure for performance, reliability, and compliance.
