Facebook

Working on Machine Learning and Deep Learning modeling efforts for better user targeting for Stories at Facebook.

Senior Machine Learning Engineer & Tech Lead

Ads growth: Dynamic Ads Creation and Targeting using Machine Learning

Software Engineering Intern

Teaching assistant for CS221: Artificial Intelligence

Graduate Research And Teaching Assistant

Course assistant for CS276: Information Retrieval and Web Search. We look into questions like how to make a search engine, like Google. How to optimize it and come up with novel approaches to rank web pages. How to mine the internet for relevant information.

We try to take a research approach, trying to look and push the boundaries of the state of the art techniques, while also staying grounded and coming up with algorithms/approaches that can scale really well in the industry and make a crucial difference in efficiency for these systems.

At the Natural Language Processing (NLP) group.

Graduate Research Assistant

Yelp

Working on the Business Analytics and Modeling team as a full stack engineering intern. My summer project is to develop the data-pipeline monitoring system for finding potential loss of Kafka messages in Yelp's distributed producer-consumer model.

Georgia Institute of Technology

In Spring 2015, I am also teaching a distance learning course along with regular 3 and 4 dimension calculus. As a part of that, all my lectures can be found on Mcgraw Hill Gatech portal and this semester, 80 more students are part of my online recitation. In total, I am responsible for 100+ students.

Head & Super Undergraduate TA for Calculus 3 (MATH 2401)

Worked with 3 other TAs to conduct weekly 3-hour verbal, written and instructional lab sessions for Digital Design Lab at the School of Electrical and Computer Engineering, Georgia Institute of Technology.

Helped 30 2nd and 3rd year ECE/CS students with conflict resolution, problem solving and help them develop an overall understanding on how digital electronics work.

Undergraduate Teaching Assistant for Digital Design Lab

Working with Greg Mayer, post-doc at School of Mathematics, Georgia Institute of Technology. Using statistical models to analyze online teaching interactions. Funded by Georgia Tech President’s Office

Undergraduate Research Assistant at Math Department

In Fall 2013, we are developing a mobile application to be used by Tech students to access & finish homework on tablets. This will include a personalized flashcard app for students to review concepts & enhance student-instructor interaction.

Undergraduate Research Assistant under Dr. James McClellan

Undergraduate Teaching Assistant for MATH 1502 - Calculus II (Fall 2013) and MATH 1712 - Calculus and its applications (Fall 2012). Responsible for mentoring Undergraduates enrolled in the class, teaching and revising all important concepts,conducting and supervising quizzes, midterms and finals. In Spring 2014, I am also teaching a distance learning course along with regular calculus. All my lectures can be found on Mcgraw Hill Gatech portal

Undergraduate Teaching Assistant at Math Department

Doing research as a part of Vertically Integrated Projects (VIP) under Dr. James McClellan on Intelligent Tutoring System for ECE 2026 (ECE 2025) - Introduction to Digital Signal Processing for 3 semesters.

In Spring 2014, I am also teaching a distance learning course along with regular calculus. As a part of that, all my lectures can be found on Mcgraw Hill Gatech portal and this semester, 30 more students are part of my online recitation.

Super & Head Undergraduate Teaching Assistant at Math Department for Distance Learning

As a lead teaching assistant, I am responsible for managing 200+ students who are taking advanced Calculus and Linear Algebra and coordinate with other TAs to make sure that everything runs smoothly. I conduct and weekly quizzes, homework, midterms and final examination. Also, I teach 35 of these students twice a week.

Lead Undergraduate Teaching Assistant for Advanced Calculus and Linear Algebra

In the spring semester, we took the idea of intelligent review to the whole different level by deciding to arrange all the questions differently for every student based on their strengths and weaknesses. For that, we chose to have a concept based approach and thus we used probability based models, cross correlation among different concepts and also developed a suitable mathematical trend ,based on the data for the last 6 years. 
With all this, we were able to classify all the concepts into 5 tiers (with Tier 0 being the most difficult) and all the corresponding questions accordingly (this was trickier since a challenging concept could have an easy concept associated to it.)
After doing all this data mining and all the computation, we were able to get a list of all the concepts that were really important for any particular student and using this information, we decided to make binary 'questions' trees. For this, we had to make another model that took into account the ease and the effectiveness transition from one concept to the other. For this, we tried alot of series and compared our data with the past years data. After trying 10 or so models, we settled on one model and finally made the binary trees, thus totally redefining the whole system. 

This implementation will be used by Georgia Tech students starting Fall 2014.

I was a full time student at Georgia Tech Lorraine, France and I visited more than 15 European companies while taking core ECE courses like ECE 2031, ISYE 3770 and Differential equations etc.

Study Abroad Student

I was a tutor for Mathematics and Physics at Clough Undergraduate Learning Commons. A part of responsibility was to teach (both 1-to-1 and group) students,  answer their doubts and kindle their interest in the subjects.

MATHLAB Teaching Assistant

In Fall 2012, We designed and implemented algorithms, using N-gram analysis, for the Intelligent Tutoring System which currently in use at Georgia Institute of Technology. Our m*n list implementation for the concept base improved the student online question search system efficiency by 53%. 

In Spring 2012, we completely did a redesign and auto arrangement of concepts within the Intelligent Tutoring System using 3 level integration and I also proposed Instructor Assignment Creation system. Overall, our project was able to improve the system's efficiency by 29%.

Undergraduate Research Assistant under Dr. James McClellan- Concept Refinement Team

University of Oxford

I got the wonderful opportunity to study at Oxford university, UK and further expand my international experience. 
For the first 6 weeks, we were accompanied by our professor on a journey through major countries of Europe and then for the last 6 weeks, we were students of the prestigious Worcester College at Oxford.

Student of Math | Art | Music | Architecture 

Enterprise2Empower

I was the Vice President of Technology at Enterprise to Empower, an emerging student organization at Georgia Tech focused on entrepreneurship 

used LAMP architecture to maintain the organization marketing website and logged in experience

Vice President - Technology

With a focus and deep expertise in machine learning and all things AI, my journey has evolved into the role of Cofounder and CEO at Kintsugi, where I apply my technical prowess in Machine and Deep Learning to create vertical models that serve as indirect-tax engine that power Kintsugi AI. 

My tenure as a Senior Machine Learning Engineer at Facebook was marked by significant contributions to ML filtering and Ranking models, enhancing the precision and effectiveness of Fb, Instagram and Messenger Stories product. The skills honed there now underpin my strategic direction at Kintsugi, guiding a team in crafting cutting-edge, AI-driven contextual models.
