Senior DevOps Engineer
Reliable platforms.
Safer releases.
Less firefighting.
I build and operate the infrastructure behind software. AWS, Kubernetes, and automation—with production reliability at the center.
Currently at Nemetschek Group · BluebeamCloud infrastructure. Real production problems.

01 / THE APPROACHGood infrastructure
Good infrastructure
makes room for good work.
I’m Srivardhan Reddy Kolan, a Senior DevOps Engineer based in Hyderabad. My path started in Linux and application support, then grew into cloud infrastructure, Kubernetes, and platform engineering.
I like the work between a system working once and a system working reliably: repeatable infrastructure, thoughtful release controls, useful monitoring, and a clear understanding of what went wrong.

Repeatable infrastructure, reviewed as code.
Delivery & GitOps
Make the path to production safer.
Observability & Operations
Understand the system. Find the cause.

03 / SELECTED WORKReal systems.
Real systems.
Considered decisions.
A closer look at problems I’ve worked on.
Based on my professional experience.
DEPLOYMENT GOVERNANCE/01
Parent pipeline
→Approval gate
→Terraform
Illustrative Command Demo
Example command: terraform plan. Example output: Configuration validated. Plan ready for review. Production approval required. This is an illustration, not a live system.
A deliberate gate before production.
GitLab approval controls that protect infrastructure changes before a downstream pipeline starts.
Explore the work +
The context
Production infrastructure changes need an explicit approval boundary, including when a parent pipeline triggers downstream Terraform jobs.
My contribution
Designed and validated Protected Environment controls and parent trigger-job behavior using environment action:start before downstream execution.
The takeaway
Approval behavior needs to be validated across pipeline boundaries, alongside the infrastructure plan itself.
PRODUCTION RELIABILITY/02
Signals
→Cluster analysis
→Root cause
Illustrative Command Demo
Example command: kubectl get pods. Example output: api-server 1/1 Running. worker 1/1 Running. Workloads ready for inspection. This is an illustration, not a live system.
Follow the signal. Find the cause.
Incident analysis across applications, Kubernetes, and the underlying EC2 infrastructure.
Explore the work +
The context
Kubernetes symptoms can originate in workload sizing, application health, or the nodes hosting the cluster.
My contribution
Investigated Redis degradation, memory-driven pod evictions, HPA/request mismatches, and NodeNotReady events caused by EC2 hardware issues. Documented findings for follow-up.
The takeaway
Useful incident response connects workload signals to infrastructure evidence and leaves a clear RCA for the next engineer.
PLATFORM VISIBILITY/03
Metrics
→Cost allocation
→Visibility
Illustrative Command Demo
Example command: kubectl get svc opencost. Example output: Service: opencost. Cluster metrics available. Ready to explore allocation. This is an illustration, not a live system.
Make infrastructure costs visible.
Evaluating Kubernetes cost visibility to support better showback and chargeback conversations.
Explore the work +
The context
Cluster-level cost visibility helps teams understand resource ownership and discuss infrastructure spend.
My contribution
Evaluated OpenCost with VictoriaMetrics and compared cluster-level insights against existing SaaS cost tooling.
The takeaway
The focus was evaluating cost visibility patterns and the information available to teams.
04 / ALWAYS EXPERIMENTINGProduction mindset.
Production mindset.
Home lab curiosity.
A Proxmox-based playground for learning by doing. I explore Kubernetes, self-hosted tools, automation, and local LLMs—then bring that practical understanding back to platform engineering.

Illustrative Command Demo
Example command: cat learning.md. Example output: Proxmox: Virtualization & Self-hosting. Kubernetes: Containers & Orchestration. Observability: Metrics & Dashboards. Local LLMs: Exploring AI Infrastructure. This is an illustration, not a live system.
