7 years. 5 enterprises. 2 real banks.

I head the entire defensive security division — Cloud, Infrastructure, Network, Endpoint, Data Security. Led 5+ engineering teams across enterprises. Production environments where mistakes have real consequences.

I've built and shipped apps in prod. Architected GCP infrastructure from scratch. Implemented security tooling most teams only read about. Been on incident calls at 2am.

I also give lectures at colleges across India — because this knowledge shouldn't stay locked inside corporate Slack channels.

So I started TechWithVarun.

Real Cloud and Security architecture. GCP deep dives. DevSecOps pipelines. AI tools that actually work in regulated environments. War stories from the trenches — anonymised, honest, and worth your time.

No recycled content. No fluff. Just real stuff.
