Ever since I was a kid, I was good with numbers and loved solving challenging problems. I fell in love with Data Science while building my first predictive model at Loylty Rewardz(LR). The fact that I could predict the future totally blew my mind and I have been hooked onto ML & AI ever since.At LR, I analyzed billions of transactional and demographic data points to generate actionable consumer insights. Having developed and implemented an analytics-focused database helped me hone my SQL skills. Python came in really handy while developing custom applications for automating processes. These experiences enabled me to deploy end-to-end ML solutions for key business problems at LR.I have been fortunate to work with and learn from very smart people all throughout my life. My passion for learning brought me to San Francisco - the startup capital of the world - where brilliant minds from all over the world solve the most challenging problems. As a master's student at USF, I implemented key ML algorithms from scratch and developed a much deeper understanding of data science concepts. Upon graduating, I joined Factspan Analytics where I got the opportunity to solve business problems in diverse domains like online experimentation and grocery order fulfillment. My long-term vision is to use my data science and engineering skills to improve people's lives in a meaningful and sustainable way. In the near term, I want to build scalable products and services and learn from the best minds in the industry. This gels well with my current role at Shipt, where I am optimizing gig-worker pay to drive bottom-line growth and make our marketplace more efficient for all levers.GitHub: https://github.com/ShishirKumar93Personal Website: https://shishirkumar93.github.io/
