ABOUT ME
Devops Automation Engineer/AWS Solutions Architect in love with Python
Devops Automation Engineer/AWS Solutions Architect in love with Python

I started as an all stack web developer and pivoted in QA Automation for nearly two years.
Now I manage a testing team while I work mostly on DevOps and Cloud automation.
Whatever I get my hands dirty with, I always improvise ways to automate the hell out of it.

Life is short to do the same thing twice.

I am used to work in ever evolving environments with rapidly changing demands and priorities.
I always tackle the hardest problems through analysis, experimentation, design, and elegant implementation.
My productivity stems from loving what I do so I always give my 100%.
I will always have the strong desire to learn and leverage the best tools and techniques in order to make stuff work better, faster, stronger.
