I buildwebsiteswebsites, web apps, backends, platformsthat hold up.

I'm a software engineer in Hyderabad, currently at Deccan AI. I build websites, web apps and the backends behind them: APIs, queues and clusters that stay correct under load.

Next.js and React on the front, Go, Python and Java behind it. Open to full-time, contract and freelance work.

01Deccan Vault

View project
  • This is Deccan Vault. I built the whole thing, front to back.

02Keploy

View project
  • At Keploy I taught tests to fake a database.
  • It reads MongoDB's wire protocol straight from raw bytes.
  • Then replays live Kubernetes traffic across seven protocols.
