// 01. About Me

Who Am I?

I'm Periyasamy K, a DevOps Engineer based in Bengaluru, India. My journey started in IT support at Persistent Systems, where I built a solid foundation in AWS cloud services and user infrastructure management.

At iOPEX Technologies, I evolved into a full DevOps role — managing production CI/CD pipelines at scale, driving cloud cost optimisation, and ensuring 24/7 operational excellence with sub-minute incident response times.

I'm passionate about automation, observability, and building reliable, self-healing infrastructure. I thrive at the intersection of development and operations.
