Ajay Balakumaran
Bangalore
Summary
An upbeat and self-motivated developer whose prime area of expertise is Python Development. I discovered the world of Python and developed a bot to communicate with user. I consider myself a forever 'student', eager to build more applications. I am equally passionate about running so much that I could 'run for my life' with nothing chasing me. When I am not coding or running, I travel or find ways to stay fit.
