Sai Kiran Gajjala

Associate

It may sound clichéd - being a software engineer and all - but I love writing code! Ever since writing my first program in C# and manipulating it to give me the results I sought, I have been obsessed with the idea of using software to solve practical problems. Apart from investing my time in understanding and learning how to code better, I like to follow technology trends, and unwind with movies.
