Experience
Fast Science
Fast Science is a web-based application built on React. The purpose of the app is to make cutting-edge research available to the masses. It's a platform to publish interactive summaries of the latest patents and research papers that can be consumed by students, working professionals, and researchers to accelerate learning and achieve breakthroughs.
Framebench — Google Docs for Creative Professionals
https://techcrunch.com/2013/02/22/framebench-is-a-google-docs-for-creative-collaboration/Framebench was developed by me and the co-founder Rohit in collaboration with an established animation movie production house based out of Pune, India.
The studio did daily reviews with their creative directors sitting out of the US. Framebench was built to help them create well-defined tasks out of this feedback. Further, they could compare newer revisions with previous ones to see if all the feedback was implemented.
Eventually, Framebench was expanded to include other media types, namely images, PDFs, and other documents.

Tinsel — Mobile Shopping Got a Makeover
https://youtu.be/KHsEJnXesRsThis was an independent project. It was housed at one of the leading e-tailers in India. The idea was to let people express interest in items they'd like to shop while watching videos. It was frozen due to content licensing issues.
Circuit Simplifier
https://www.slideshare.net/VineetMarkan/circuit-simplifierI presented this project at a National Tech festival, bagging the best Computer Science award and some (modest) prize money. The idea was to take an entangled overlapping circuit from a breadboard and create a minimally overlapping orthogonal circuit that can be embedded on chips.
Birch — Connecting Video Creators to Businesses
https://www.youtube.com/watch?v=S2bjrO_yU5oBirch helped organizations like Uber, Ola, and the Govt. of India to find top video creators in locations they wanted to shoot video and work with the best creative talent.
I founded the business, built the platform, and worked on business development to get more clients on the platform.
