Background

I'm a CS Graduate who is extremely passionate about what I do. I also love to share my knowledge in the best way possible.

I like to simplify complex concepts and implement it in the best way possible. During my under graduation, I explored different domains, and every time I explored something, I came back to Backend Development. It is then, when I found it to be what I love.

I love Backend software. It excites me the most, distributed architecture and handling scalability problems is what I'm trying to do now-a-days.
