Hi, I'm

Rajesh Medampudi

Engineering Leader · Builder · Bitcoiner

17+ years building production systems at scale. I lead engineering teams, architect distributed platforms, and obsess over infrastructure that runs well and costs less. Currently a Technical Manager at Head Digital Works.

I write about AWS, self-hosting, Bitcoin sovereignty, and the thinking behind hard decisions.

What I work on

Observability Cost Revolution

Replaced $40K/month Datadog + $40K/month CloudWatch with a self-built Grafana LGTM stack. ~$120K/month prospective savings across 15 departments at 6 TB/day.

Real-Time Systems

Architected a targeting engine with Java 21 virtual threads processing millions of events at <500ms p99.

AWS Cost Optimization

Right-sizing, Karpenter, Graviton, and lifecycle policies across production infrastructure. Zero performance loss.

Self-Hosted Infrastructure

Run my own Kubernetes clusters, observability stack, and services on bare metal. No cloud lock-in.

Writing

Technical deep dives, building in public, Bitcoin, and first-principles thinking.
