Who are India's Top Four Fortune Tech Czars?

Four Indians are named in the Fortune magazine's list of 20 technology czars with "extraordinary" talents to analyze and process data into information transforming "the way business operates."

Arun Murthy, Surabhi Gupta, Swatee Singh and Vijay Subramanian are the four Indians who have been listed on the "Big Data All-Stars" category, which lists the people "best at connecting the dots and digging deep."

Murthy is the co-founder of Hortonworks, a business computer software company based in Palo Alto, California. Prior to this, he had worked with Yahoo, where he kick started his career.

According to the magazine, Murthy was in the team which developed a resource and workload management system called YARN that acts as a sort of operating system for Hadoop. A prototype, Apache Hadoop was open-source software made for large scale storage and processing of web's big data.

Gupta is said to have an art of summarization, which helped Airbnb— a website to help book lodgings for travel trips—to improve its search engines in just four months.

She is currently working on condensing all of Airbnb's listings to create summaries that can enable users to understand different cities' vibes, Economic Times cited the magazine. Before joining Airbnb she worked with Google.

Another Indian talent on the list is Swatee Singh. She is the Vice President of GSM Instant Messenger Platforms and Big Data Capabilities at American Express (AE) focusing mainly on making business personal.

She is said to be the mastermind behind AE's "MyOffers," that gives members "what they want when they need it," and she also developed a tool made for merchants to compare their annual performance.

While Subramanian, another tech czar, "built a model to estimate missed demand, product longevity, and occasion usage for the company's inventory--a huge cost-saver for a company that buys truckloads of dresses and accessories from fashion designers every season to rent to customers."

As the Chief Analytics Officer at Rent the Runway, Subramanian is focused on his next project to incorporate new types of data from Unlimited— the company's major new expansion into everyday wear, Fortune said.
