Android @ Booking, Ex - VP Tech @ SnipClip, Ex-Android Ninja @ Inshorts - 4 Million+ Downloads
"Ishan is where the tech is" defines me precisely. I am a passionate product enthusiast and an open source evangelist who loves hacking at Hackathons and speaking at conferences.
Being an avid hackathon lover-thinker-innovator, I won 1st Prize at PolicyHack by EPOD at Harvard University and 2nd Prize at HackCancer by EPIC @ Boston University. As an active contributor in the Mifos community, I was invited as a speaker at Global Mifos Summit in Sharjah, UAE (March, 2015) and chosen as a delegate for Mifos at GSOC Reunion in California, USA (October, 2014). I've also attended PennApss XII, the world's largest collegiate invite-only Hackathon hosted by University of Pennsylvania (September, 2015).
I successfully graduated as a Google Summer of Code Intern in 2014 under Mifos and in 2015 under XMPP Standards Foundation.
Recently started working as an Android Engineer at Booking.com in Amsterdam, Netherlands. Also work as a contributor and mentor for the Android Projects at Mifos Initiative, an Open Source Micro Finance Platform.
I mostly write Java in my day-to-day adventures with Android SDK. But I love scripting and automation so I also keep delving into Shell and Python. I have sound working knowledge of full stack web development environment, from setup to scale.
