all systems operational

Nihar Padhi

AWS DevOps / Cloud Engineer

I keep production infrastructure running on AWS — operating and automating what the business runs on. And when it breaks at 2 AM, I'm the one who finds out why, and fixes it.

incident log

When it breaks, I find out why.

Production doesn't fail politely. Here's the incident log — real events I diagnosed and drove to resolution, the evidence-first way. Hover a marker to open the report.

P1 · criticaldb-saturation

Database saturation at peak

A severe peak-hour database overload traced to a scheduled-job collision. I followed the evidence through the web tier and drove the fix — read replica, load-aware autoscaling, and connection limits.

P1 · criticalscaling-blind

A scaling failure nobody could see

Recurring instance replacements turned out to be I/O-bound media traffic invisible to CPU-based autoscaling. I disproved the team's first hypothesis with metrics, then fixed the scaling signal itself.

NET · outagelogin-block

Login outage from a security-group misconfig

Auth calls were blocked before reaching the app. I isolated it to a security-group and routing issue and remediated with WAF allow-lists and routing changes — tradeoffs written down.

GCP → AWS production migration

Contributed to a production migration with minimal downtime — secure multi-tier VPC design and reusable Terraform modules for repeatable, reviewable deployments.

the day-to-day

Most of the job is keeping the lights on.

AWS-certified DevOps engineer. Most of my day is operational — triaging alerts, resolving infrastructure tickets, investigating failures, reading logs and AWS Health events, keeping backups green, and writing evidence-based RCAs when something goes wrong.

Alongside that I build and maintain the infrastructure itself with Terraform, CI/CD pipelines, and containers on Amazon ECS. Because the team is small, I work the whole stack — network, compute, data, security, and cost — rather than one narrow slice.
