Tarak Kar

I’m a results-driven Lead Data Engineer with 14 years of total IT experience and 10 years focused on designing, building, and optimizing scalable data pipelines and architectures. I bring deep expertise in big data technologies, cloud platforms, and data governance, and I thrive on leading cross-functional teams to deliver high-impact data solutions.

At Tata Consultancy Services, I led the end-to-end development of a Reservation Data Warehouse enabling near real-time insights into revenue, bookings, occupancy, and customer trends. I designed data models with ErWin and transformations with dbt on Snowflake, built Kafka-based streaming pipelines for high availability and consistency, and orchestrated automated ETL workflows using Airflow, SQL, Python, and Shell scripting—cutting data retrieval times by 21%.

Previously at Unvired Inc, I built SAP Sales Order and Order-to-Cash warehouses using AWS Glue, Databricks/EMR (Spark), Amazon Redshift, Airflow, and Power BI, including multi-fact star schemas for accurate metrics. I also delivered real-time IoT energy pipelines with AWS IoT Core and Greengrass, designed S3-based data lakes and streaming architectures with Amazon MSK, and implemented monitoring and governance frameworks to support data security compliance; earlier, I developed ERP solutions as a Full Stack Developer using microservices with Flask, .Net Core, PostgreSQL, Docker, and Angular.
