About

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.

Undergraduate Research Assistant under Dr. James McClellan

Jan 2014May 2014 · 4 mos

  • 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.
