Senior Technical Lead at Parallel Wireless
Building reliable platforms for Kubernetes, edge & infrastructure.
I'm a platform engineering and DevOps professional focused on Linux, Kubernetes, edge infrastructure, bare-metal automation, production reliability and practical AI-assisted engineering.

Current role
Senior Technical LeadParallel Wireless
2021 — Now · Bengaluru, India
I lead the design and delivery of Kubernetes-based edge cloud platforms for telecom customers: from powering on bare metal in an air-gapped site to running, upgrading and monitoring the clusters on top.
Cloud projectsAmazon EKS on AWS with Terraform, covering VPC, EC2, IAM, security groups, load balancers, EBS/EFS storage and EKS upgrades
- Own the full lifecycle of Kubernetes platforms (upstream kubeadm, EKS Anywhere and RKE2), from cluster design and deployment to upgrades, maintenance and monitoring
- Deploy and operate edge Kubernetes clusters at remote, often air-gapped customer sites, as well as large on-premise clusters across many bare-metal nodes
- Architected zero-touch provisioning that takes bare metal from power-on to a ready Kubernetes node with Tinkerbell, Metal3, PXE/iPXE, Redfish and cloud-init
- Built EKS Anywhere and RKE2 simulations on KVM that catch integration and upgrade issues before QA
- CI/CD for immutable node OS images (ISO, QCOW2, VMDK) with TLS/mTLS, PKI and certificate lifecycle
- Hands-on Linux under every cluster across RHEL, Ubuntu and SUSE (SLE Micro), from systemd and SELinux to kernel tuning and troubleshooting
- Brought AI-assisted engineering (Claude Code, MCP servers, AI PR review, simulated test scenarios) into daily platform work

What I work on
The problems behind reliable infrastructure.
Not individual tools, but the systems that turn racks of hardware into platforms teams can trust.
Kubernetes & Platforms
Design, operations, troubleshooting and lifecycle management.
- Upstream Kubernetes, EKS, EKS-A & RKE2
- Cluster architecture & security
- Networking, storage & upgrades
Cloud: OpenStack & AWS
Private and public cloud, from hypervisors to managed Kubernetes.
- OpenStack: Nova, Neutron, Keystone, Ceph
- AWS: EC2, VPC, IAM, ELB, EBS/EFS
- Amazon EKS with Terraform
Bare Metal & Edge
From powered-off hardware in a disconnected site to a production-ready cluster.
- Tinkerbell / Metal3, Redfish / IPMI
- Air-gapped edge provisioning
- iPXE, cloud-init & immutable OS images
IaC, GitOps & Delivery
Everything as code, shipped through pipelines rather than by hand.
- Terraform, Ansible, Bash & Python
- GitOps with Argo CD
- CI/CD for images & platforms
Platform Security
Identity, trust and hardening built in, not bolted on.
- PKI, TLS/mTLS & cert rotation
- OIDC / SSO login & RBAC
- Supply chain: signing & scanning
Production Reliability
Incident investigation based on evidence, measurement and system behaviour.
- RCA & troubleshooting
- Observability: metrics, logs, traces
- Performance analysis
AI for Infrastructure
Using AI as an engineering multiplier for diagnosis, development and automation.
- MCP servers & agent workflows
- AI PR review & test simulation
- Spec-driven, not vibe-coded
Technical Leadership
Turning operational problems into repeatable engineering systems.
- Architecture decisions
- Technical mentoring
- Automation strategy
How I build
Four rules I've learned the hard way.
Boring is a feature.
The best platform is the one nobody has to think about at 2 a.m.
If it isn't rehearsed, it isn't recovery.
Backups, failovers and certificate rotations get drilled, not assumed.
Automate the second time.
Do it by hand once to understand it; then make it impossible to do wrong.
Measure what users feel.
Green dashboards mean nothing if the product is down.
Writing
