I am a generalist software engineer who has worked across the stack and is equally comfortable with scaling up services as well as creating beautiful 2D and 3D visualizations.

I am a full stack developer, willing to get his hands dirty in order to get things moving. I don't believe in working in silos. I find it comforting to understand all layers of a stack.

I have worked closely with stakeholders for building scalable solutions while managing teams of developers.

Interests

Apart from being a developer, I enjoy most of my time being outdoors. I like playing Table Tennis, Chess, Beach Volleyball and Soccer. Swimming is my favorite thing to do in summer.

Indoors, I follow a number of sci-fi and fantasy genre movies and television shows, I am an aspiring musician, and I spend a large amount of my free time exploring the latest technology advancements in the development world.
