You should check out my current projects.

I started programming in 1999. Starting with C, I finished many projects with Java and Javascript before discovering and falling in love with Ruby. I co-founded a B2B startup ( which was a social CRM app) and learnt a lot. The companies I have worked with include GupShup, Truweight, HyperTrack, and ClearTax among others. My skills range from web & mobile apps to electronics hardware to machine learning or algorithmic trading to topics like syllogisms, aerodynamics and mathematics behind music theory.

Inspired from Bret Victor's famous talk, I made this prototype for live coding. The idea is that as you code, the tests are run automatically and their status is immediately visible to the programmer.
