About

I am a seasoned engineering leader with a proven track record of delivering impactful solutions for startups and large enterprises. I have a passion for building and leading high-performance teams across geographies and domains. As the VP & Global Head of Engineering at WorkSpan, I have successfully scaled the engineering organization to 80+ engineers in India and Europe, while driving revenue growth by 3x and securing Series C funding. As a key member of the executive leadership team, I have set up and grown the India development center from scratch. I have a strong technical background with a focus on building systems that scale. I have delivered critical 0-1 initiatives to grow WorkSpan revenue, such as co-sell applications with leading cloud providers, and built innovative core platform capabilities, including dynamic multi-company data models, multi-source integrations, reference data management, and a business process automation framework. Prior to WorkSpan, I co-founded MathChat, an innovative mobile app for math collaboration that reached over 350k downloads and was featured in the top 50 education apps on the AppStore. My open-source contributions include iosMath, a library for typesetting LaTeX equations in iOS applications, MathEditor, a WYSIWYG editor for math formulae on iOS, and Dgraph, a graph database written in Golang. I have worked at both large companies such as Amazon and Google as well as various startups, including RichRelevance, Ning and Socrata, where I built new innovative models for the recommendation engine, improved and scaled the model building infrastructure by moving to Hadoop, and developed classification algorithms on Hadoop. As an engineering leader, I take pride in creating a fun and engaging culture to keep the team motivated and keep attrition rates low. I have set up the engineering processes and strategy for hiring, promotions, releases, and quality. I have also organized the team into small independent units to improve execution velocity. Additionally, I built the Quality Engineering, SRE, and Technical Program Management functions from scratch. Overall, I am a hands-on leader with a proven track record to turn teams around, build high-performance teams, and deliver critical 0-1 initiatives to grow revenue. I have a strong technical background with a focus on building scalable systems, and I thrive in fast-paced, high-growth environments.
