About

Soumojit is passionate about data based decision making and brings an expertise in Operations Research (OR)/ Actuarial Modelling/ Artificial Intelligence, handling end-to-end implementation of advanced Optimization / Machine Learning capabilities, with rich experience of delivering quantitative models across multiple domains and various diverse range of industries including Supply Chain & Inventory Optimization, Pricing Optimization, Ad-Tech Demand Allocation, Airlines Revenue Optimization and Actuarial modelling. Soumojit has completed PhD in Operations Management from IIM Calcutta in 2012. His thesis topic is titled "Mathematical Programming for Product Line Decisions: An Integrated Approach"​. The thesis revolves around modelling how firms will decide on the optimal product line to maximize profit, revenue, market share when faced with constraining situations like diverse preference patterns' from customers, increasing cost to improve quality, supply chain complications and underlying market forces. The thesis is built up of four Operations Research (OR) models to facilitate the decision making process of the firm. Soumojit is vastly experienced in handling large scale optimization and built reusable and software products in Python, Java using optimizers like ILOG CPLEX,Gurobi, X-PPRESS aimed for industrial use and decision making in proper planning. To solve the large scale optimization, most of the times it becomes inefficient to solve through commercial solvers. He has developed heuristics or algorithms to solve these intricate NP-hard problems, and all of them have been published in highly acclaimed international journals in Operations Research(OR) area. Soumojit is expertised in developing and delivering software products implemented programming languages like Python, Java and well-versed to state-of-the-art Machine Learning, Deep Learning, NLP and Computer Vision techniques. Previously he has completed Bachelors of Engineering (B.E.) in Electrical Engineering from Jadavpur University, Kolkata. He is also in the practice of periodically providing trainings in the above mentioned areas to both corporates and academic institutes. Recently, he has completed CFA charter from CFA Institute, USA and FRM from GARP, USA.
