I'm currently a Senior Software Engineer at Google.

In the Cloud AI team, we are building Conversational AI products leveraging state of the art Large Language Models.

I have led the launch of various features to help summarize conversations and to help search from knowledge bases. I have also helped improve the software architecture to simplify systems and increase development velocity.

At Oracle, I led the development of end-to-end Machine Learning workflows within AI Apps as well as their deployment on Kubernetes. I helped improve the performance of product recommendation models.

I also contribute to the Machine Learning platform, simplifying how Machine Learning models are trained and served.

I've previously led design, development and deployment of a system for creating and serving knowledge graph of entities extracted from the source code to enhance code discovery.

At eBay Inc I contributed to Apache Kylin, an open source Distributed Analytics Engine from eBay Inc, re-routing the queries not supported by Apache Kylin to Hive on Spark.

This gave me exposure to some of the most important technologies & services in distributed systems like Hadoop, Spark, HBase, Hive, Kylin, Ambari, HDP, Zookeeper, Tomcat, etc.

This is also where I met one of my best friends, Docker, who was a 6 month old kid back then. :)

At connecto.io, I developed a scalable web crawler using MEAN stack to find add-ons used by millions of websites.

We also predicted engagement scores for websites by analyzing features like visibility of call to action, contrast ratios and link densities using OpenCV library in Python.

This gave me exposure to the power of MEAN stack and also to an interesting domain of image processing.

Machine Learning

My love for Mathematics and Computer Science has driven me towards Artificial Intelligence and Machine Learning.

I am an active member of meetups related to Machine Learning around the Bay Area.

I find Machine Learning Research even more fun. You can find more about my academic research work here.

Photography

I have always loved taking photos. I learn something new everyday.

I believe in the power of visuals. It's a language we use to see into each other's lives, one frame at a time.

Large Scale Object Identification and Image Captioning using GPUs and Apache Spark

I've worked with Dr. Sourangshu Bhattacharya on Large Scale visual recognition (precisely dense image captioning) using Deep Learning on GPUs and Apache Spark.

Along with this, I worked with Spark community for efficient implementation of CNN and RNN in Apache Spark.

While working on this project, I also came across using convolution neural network to mix the content and style from different images. So, I implemented that and the results are very encouraging.

Author Profiling from Personal Content Blogs

Predicting gender and age of the author using semantic features.

This project involves predicting personal information of authors like gender, age etc by training classifiers using content based and semantic features extracted from a KB like Wikipedia.

There is a lot of contextual difference between blogs written by different people. In this project with Prof. Pawan Goyal, we explored those contextual differences to predict age and gender of the author of a text.

Modeling Retweet Dynamics using Hawkes Process - A Temporal Approach

In Twitter, mentioning (or tagging) users can be considered as an effective way of spreading an information beyond the reach of the followers.

The objective we had is to model retweeting patterns based on historical data of user interactions, inherent topical similarity between tweets reaching current user and tweets of his top K friends, and the nature of interactions of a user with his neighbours in the social network.

Point Processes have recently received significant attention from researchers in social media analytics. We have modelled Hawkes Process for online social networks to investigate retweeting patterns.

Kibitz

Have you ever found yourself googling about the new term your friend just tossed in a chat? Or searching for a video comparison to win a iPad vs Surface battle with your buddy. Don't need to do that any more.

Kibitz is an interactive chat application, I built along with my friend Arkanath, which automatically finds out the context of the chat and gives real time feeds of the related content from the web, including videos, definitions, news, etc.

Moreover, it also personalises your chat experience by changing the background based on the chat content.
