Possible rewritten summary: In Amazon, I managed the data engineering projects and operations of the ad program of Amazon Advertising, delivering streamlined and efficient data pipelines that enhance data accuracy and accessibility. I have developed and maintained robust ETL pipelines using AWS Glue, leveraged AWS Redshift for data warehousing, and crafted insightful SQL queries to provide valuable insights from data. I have also utilized AWS S3 for scalable and cost-effective storage solutions, implementing data partitioning and lifecycle policies. Previously, I was a Software Developer at the Ministry of Housing and Urban Affairs, where I designed an intelligent urban bus transit system for Kolkata from scratch, optimizing the costs and efficiency for both the operator and passengers. I applied my data science and machine learning skills to modify a metaheuristic genetic algorithm, implement a support vector machine model, and extract passenger data using web scraping techniques. I hold a Bachelor of Technology degree in Chemical Engineering from IIT Kharagpur, where I also completed several projects related to spatio-temporal data simulation and generation using deep learning techniques, such as GANs and PRO-GANs. I am passionate about data engineering and data science, and I am always eager to learn new skills and technologies to solve challenging problems and create impactful solutions. I am also an AWS enthusiast and a certified TensorFlow practitioner. Let's connect!
