Some of the things I have built over the years
You should check out my current projects and my GitHub profile.
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, ClearTax and WhatsApp among others. My skills range from web & mobile apps but I have dabbled in things like electronics hardware, machine learning, algorithmic trading, aerodynamics and mathematical 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.
