Employment
Experience
- Angular Drag & Drop library
I built one of the most popular drag and drop libraries for Angular.JS 1.0. It supported complex nested lists and used the HTML5 drag and drop API. It gained over 2,000 GitHub stars and millions of npm downloads.
- Google Search: Suggesting Related Pageshttps://www.androidpolice.com/2017/11/06/sliding-people-also-view-card-showing-scrolling-google-app-search-result/
I led the technical design and implementation of a new feature in the Google app for Android that suggests related pages to users while browsing through search results. This required close collaboration with the ranking team that was providing the back end and involved overseeing the launch process, including metric analysis.
- Google Guava: Optimized Base64 Encoding by 70%https://github.com/google/guava/commit/2fe1415c5c2a1ee771a1616cc5d30d12e656026c
Google Guava is one of the most used Java libraries globally and is used by all Java projects inside Google. I rewrote the BaseEncoding class, which made encoding over 70% faster and decoding over 60% faster. This class is used by thousands of projects inside Google and many more outside of Google.
