Amit Sharma — Cloud & Platform Engineering Leader

Zero-downtime cloud migrations, SRE-grade Kubernetes platforms, and the engineering programmes that ship them.

I design resilient cloud platforms and lead the engineering programs that ship them. From SRE-grade Kubernetes to zero-downtime migrations, I own delivery end-to-end across GCP, AWS, and Azure.

What I Stand For

Principles that shape how I work

01

Zero downtime is a constraint, not a goal

Teams that achieve zero downtime design for it from day one. It's not something you bolt on at the end — it shapes every architectural decision, from dual-run strategies to rollback triggers.

02

Migrations are org problems first

The technical challenges are rarely what derails a migration program. Misaligned stakeholders, unclear ownership, and InfoSec teams looped in too late — these are the real risks.

03

Platform engineering is about enabling autonomy

A good platform team makes itself invisible by enabling other teams to move fast safely. The goal isn't to run Kubernetes — it's to make the 100 teams using it not need you.

Case studies with real outcomes

Open Source 2026

QuotaLens — Local Claude Quota Monitor

Open-source, local, self-hosted monitor for Claude Pro/Max subscription quota. Polls every minute into a SQLite file you own and forecasts whether the current session window will exhaust before it resets. Dashboard, Prometheus metrics, burn-rate webhooks. v1.0 on PyPI.

v1.0 released on PyPI; MIT open-source; macOS, Linux and Windows tested in CI

Ethan Hunt Would Blow Your Error Budget

Movies need a protagonist who goes dark, works alone, and saves the world with one second left on the clock. Incident management needs the exact opposite. Here's what the silence between first responders and stakeholders actually costs.

The Best Retention Metric Is Who Follows You and Who Outgrows You

Conventional retention metrics measure who stayed. The more honest measure is who joined your next program voluntarily, and who left because they grew into something bigger than you could offer. Both are good outcomes.

`count` Is a Production Outage Waiting for a Deletion

Terraform's `count` assigns resources by index. Delete the middle item and the indices shift — Terraform destroys and recreates everything after it. On subnets, node pools, or persistent volumes, that's not a warning. It's an incident.

Default-Deny Starts in Observe Mode

Kubernetes NetworkPolicy default-deny is the right posture — but enforcing it cold in production breaks applications and creates an incident. The right approach: observe first, map actual traffic, enforce progressively. Same staged approach as a migration.

Disk Full at 10am: Logs Are an Architecture Decision

Log storage is treated as an afterthought — set a retention, set a volume, deploy. It becomes an architecture decision when the disk fills and the logging agent takes down something else. Logs need their own failure modes designed in.

Estimates Are Architecture: Writing SOWs That Leave No Loose Threads

A Statement of Work is architecture for delivery. The same failure modes apply: if a dependency is undocumented in the SOW, it will bite you at the worst moment. The discipline is to write the SOW as if the project has already gone wrong.
