About

Currently working as MLE @ Meta in Ads Ranking team I love to solve problems and I love to code. I have experience in web based application, feature engineering and data pipelines and data science. I was the founding Machine Learning Engineer at Behavidence(mental health diagnostics startup) and also worked as Full Stack Software Developer at Atlassian. I am well versed in Python, C, C++, Java and have heavily worked on Artificial Intelligence and Deep Learning. I did my Undergrad thesis on "Application of Deep learning in Bio-Medical Diagnostics and Therapies". I was a full stack developer at Atlassian -owning critical services and flows related to Installations, app request feature and app migration and also led in releasing programs like Cloud Fortified on Atlassian Marketplace. I strongly believe that technology has a way to solve our problems to an extent one cannot imagine. Language and Framework: C, C++, Python, ReactJS, Javascript, Scala, Tensorflow and Keras
