About

Gaurav Kumar is a Data Science professional with a strong foundation in Mathematics, having over 3.5 years of experience working on various Algorithm Development and Machine Learning projects. He is currently working as a Data Scientist at OLX Autos and has previously worked at Fractal and Publicis Sapient as a Data Scientist and Senior Associate, respectively. Gaurav's expertise lies in Machine Learning, Time Series Analysis, Natural Language Processing, and Deep Learning. He is proficient in programming languages like Python and C++, and has experience working with Deep Learning frameworks like PyTorch and TensorFlow. At Fractal, Gaurav worked on Supply Chain Forecasting, Monte Carlo Simulation, and Optimization projects. He used various statistical measures of time series like Hurst Exponent, Signal to noise ratio, Energy of signal, and various business KPIs to measure the demand pattern of different raw materials. He also assigned and optimized scores based on different business and statistical KPIs, and forecasted future demand of 72 raw materials using Discrete Fast Fourier Transform, Croston Method, LightGBM, based on demand pattern characteristics of raw materials. At Publicis Sapient, Gaurav worked on Smart Recruiter (NLP), Price Optimization, and Media Forecasting & Analysis projects. He worked on a Vision-based Sectioning Algorithm to map different sections of a resume based on coordinates of bounding boxes, and on an NER model to extract different entities like Name, College, Degree, Past company, and skills from the resume. He also worked on an optimization problem to find the optimal price of a product based on existing user’s purchase behaviour, and extracted objects & text from Creatives using Google Vision APIs, performed Hypothesis testing & analysed the impact of different objects (person, animal, kid), word presence on the CTR performance of Creatives. Gaurav completed his Bachelor of Technology in Chemical Engineering from the Indian Institute of Technology, Kharagpur in 2019. He is skilled in Data Science, Research, Deep Learning, NLP, ML, Pytorch, Python, Tensorflow, Computer Vision, AI, OpenCV, SQL, Word2Vec, Pandas, and Flask. With 4.28 years of relevant experience, Gaurav is a valuable asset to any team looking to leverage his expertise in Data Science and Machine Learning.
