Building Systems
That Never Sleep
I'm Mirtunjay Kumar — a DevOps & SRE engineer obsessed with reliability, automation, and shipping infrastructure at scale.
From zero-downtime Kubernetes rollouts to multi-cloud Terraform architectures, I've spent 9+ years turning complex infrastructure challenges into elegant, automated solutions. I thrive at the intersection of development velocity and operational stability — where CI/CD meets SLA.
When I'm not tuning Prometheus alerts or writing Helm charts, I'm travelling, exploring ancient ruins, and finding inspiration in the world beyond the terminal. I believe the best infrastructure is the kind nobody notices — because it just works.

Things I've Built
Things I build and ship — open source projects and engineering challenges worth documenting.
Pigeon
AirDrop for the open web
Browser-native P2P file transfer using WebRTC DataChannels. Files travel directly between devices — encrypted, zero-server, no install required. Built with Next.js, TypeScript, Framer Motion, and a standalone WebSocket signaling server.
Azure → AWS: Legacy Migration
Reverse-engineering a system nobody fully understood
Inherited a legacy Azure product built entirely through ClickOps — no IaC, no documentation, and the engineers who built it had long left the organisation. Nobody knew the full tech stack or data flow. Took initiative to reverse-engineer the entire system from scratch: tracing domains, intercepting and mapping bottom-layer API calls, and connecting every dot until a coherent architecture emerged. Reproduced that architecture in AWS from the ground up, ran a full data migration, and deployed using a blue-green strategy. Once QA signed off on sanity checks against the new environment, traffic was cut over by rerouting endpoints — zero-downtime handoff.
In-House Slack Bot Platform
Breaking the VPN-password ouroboros — and then some
When LDAP passwords expire under standard rotation policy, users lose VPN access — and resetting the password requires the internal endpoint that's only reachable over VPN. A perfect catch-22. The solution: an in-house Slack bot communicating over bi-directional WebSockets, requiring zero firewall holes and no VPN dependency. That single unlock became a platform — powering multiple org-specific automation workflows on top. The standout: an ephemeral secret-sharing flow where secrets are encrypted, shared once, and self-destruct 30 seconds after being read.
600TB Cross-Region S3 Migration
When AWS's own tools hit their limits
Engineered a 600TB+ S3 data migration for a client from us-east-1 to us-west-1. S3 Batch Operations handled the majority of objects, but AWS's 5GB single-copy ceiling left large objects unreachable via that path. The AWS-recommended Lambda-backed workaround ran straight into Lambda's 15-minute execution limit — a hard wall at this data size. Designed a custom multipart upload pipeline on high-throughput EC2 instances, parallelizing chunked transfers to bypass both constraints and reach practical speeds across hundreds of terabytes.
Life in Frames
When I'm not deploying Kubernetes clusters, I'm exploring the world.
