Karpagam: Engineering highly scalable, complex, large-data, and parallel systems

Posted: 30th of August, 2011
I work as an Architect with Yahoo!’s Advertising Products Group (APG).

As an Architect I am responsible for building the right system in the right way and at the right time. As APG directly impacts the monetization of our various Yahoo properties – I find my role exciting, where the decisions I make in my everyday work, can actually have a direct relationship with the company’s revenues.

I have been with Yahoo for close to 3 years now and like any journey, I have experienced my fair share of ups and downs. But the one constant factor is how exciting it has all been.

Yahoo! with its large-scale distributed processing requirements, directly caters to my career focus - to engineer highly scalable, complex, large-data, parallel and distributed systems.  With Advertising Systems I have had opportunities to work on various facets like Large Internet Application Development and large-scale data mining.

When you sweat out to balance the various product asks and the tight timelines and feasibility of the solution – the ultimate high is to hear the product cheered by the customers and market managers, alike.

My usual day at work, depends on what phase of product development cycle the project is in. The planning phase have a lot of intense interactions with the products and business folks – all of us trying to work-out the requirements, functional specs. In Design phase, it is fun to work on the detailed design with the core engineers, keeping in mind the need to adhere to the standards and technologies and implement the architectural principles while also balancing the time-to-market considerations.

Phew! But the ultimate high is to hear the product cheered by customers and market managers, alike.

The best part of my work is that I get to see many different perspectives from various stakeholders, and that helps me understand even better the diverse parameters which influence product and technology decisions. And this has created the belief in me that before we build a feature or a product, we need to keep the end-user in view, and always focus on how the product can benefit them. That’s the ball we cannot take our eyes off from.

I want to make a positive impact to as many lives as I can in my lifetime. I have seen how important education is in lifting the quality of life for many people, and as a first step towards my passion for education at par for all, I volunteer some time every week with under-privileged children and educate them on creative thinking
Sushant Sinha named one of Indias top in

Sushant Sinha named one of Indias top innovators

Posted: 7th of June, 2013

Indian Kanoon search engine helps people understand their rights.

Sushant Sinha, part of the Cloud Platform Group in Bangalore, was recently named one of India’s top innovators. He was featured in Technology Review's prestigious TR35 2011 – a list of outstanding innovators in India under the age of 35.

Sushant earned his place in this exclusive list for developing Indian Kanoon, a free search engine of Indian law (Kanoon means ‘law’ in Hindi, the official language of India). The portal provides the most relevant Indian laws and court judgments in response to a query.Since its launch in January 2008, Indian Kanoonhas been embraced by the Indian public, and is empowering citizens to seek justice.

Traffic is growing exponentially - 10 times in the past year and a half. Indian Kanoon currently receives half a million unique users a month, with roughly 2.5 million page views.

And here’s why. Prior to Indian Kanoon, there was no website which provided information about Indian law, at least nothing that was easy to use. Asignificant portion of the population remained completely ignorant of their rights and privileges.

“Most existing law websites charged a hefty fee and were designed by lawyers for lawyers,” explains Sushant.”The technology was stone aged, compared to the advances in the information retrieval brought about by current search engines.”

He filled these gaps when he developed Indian Kanoon. “I started the project as a way to enrich court judgments by linking them with laws and other references. The linking turned out to be so useful that I went on to build Indian Kanoon,” he adds.

Besides the standard information retrieval techniques for relevance, Indian Kanoon brings in a couple of other innovations to make law search effective. First, it breaks down law documents into the smallest possible clause. It then determines the important law sections at the granularity of the smallest possible law section. Secondly, it tightly integrates law/statutes with court judgments, which allows automatic determination of the most relevant clauses and court judgments.

It isn’t just the man on the street who’s benefiting from Indian Kanoon. Lawyers and law students form a big chunk of the user base.

Sushant, who has a PhD in Internet Security (“nothing related to search,”) is currently working on the document enrichment framework Sombrero at Yahoo!. He balances his day job with Indian Kanoon by working on it in the night and on weekends.

On what it takes to be an innovator, Sushant believes, “It takes identifying important problems and working hard to solve them. Sometimes the identified problems are just minor issues when others view it and so what really matters is whether you are convinced about the importance of the problem.”
