Experience

Inshorts

Inshorts is a news app that selects the latest and best news from multiple national and international sources and summarizes them to present in a short and crisp 60 word or less format, personalized for you, in both English and Hindi.

Inshorts iOS app has a million plus downloads and is the top-rated news app in India.

Chosen for the Featured Apps showcase by Apple.

Sole developer.

Hoover Institution

The Hoover Institution is an American public policy think tank and research institution located at Stanford University in California.

With daily articles, op-eds, popular online publications, blogs, and audio and video series in one powerful app, users are able to delve into the issues that matter most to them as well as discover and share timely content quickly and easily.

As part of the development team at Y Media Labs, I developed this app for iPad.

USEme

USEme is the fun and fast way to browse and share skills in your area.

I developed the USEme iPhone app while working at Y Media Labs.

Houseparty

Houseparty is a group video chat app where users can communicate with each other through live video in groups of two to eight people. Simply log on to the app and you'll instantly be connected with any friends who are using it at the same time. It has lots of other features.

As a team member, I developed Houseparty app while working at Y Media Labs.

Automatic Generation of Saturation Constraints and Performance Expressions for Geometric Programming-based Analog Circuit Sizing

http://ieeexplore.ieee.org/document/5770815/
This project focuses on the development of tools and an algorithm for automatic circuit sizing. For this, the performance expressions must be automatically generated without the need for manual input of equations.

I designed a prototype program which models AC performance expressions automatically.

DataManager Class

I built a DataManager class implementation file. Its shared instance can be used for all the core data operations. It follows a proper core data stack to ensure thread safety, data persistence, multi-threading, and others. I use this class and core data architecture for most of my projects.
