04 The person behind the lab

Curiosity first.
Security always.

GTekSD began in 2018 as a place to share experiments in technology and automation. Today, I use it to build and share security tools, document what I learn, and collaborate on making software safer.

I’m Suhas Dhole, an independent security practitioner based in India. My current learning interests include application security, cloud, red teaming, and the evolving security questions around AI.
