I design and build enterprise .NET systems on Azure.

whoami

I'm Karthik Racha. I architect and build on .NET and Azure: MVC APIs in C#, SQL Server data and CI/CD pipelines, shipped for healthcare, finance, retail and government.

build

Many parts.
One system.

One app splits into services behind a gateway, then scales out. Keep scrolling to watch.

Diagram: one app splits into identity, orders and billing services. A gateway routes requests to them, they share a queue and a SQL database, and each service scales out to three instances.

Four boxes.
One lab.

The apps I expose sit behind NPM Plus and CrowdSec AppSec on a Cloudflare domain. Authentik signs me in everywhere, and Prometheus and Grafana chart the requests coming in.

I tinker with new tech every day. I'm an enthusiast, driven to understand the latest tech trends.
