About

With a Bachelor of Technology in Computer Science from Brindavan Institute of Technology and Science, completed in 2020, I have developed a strong foundation in technology and data management. Since November 2021, I have been working as a Teradata Developer at Tata Consultancy Services. In this role, I am responsible for designing, developing, and maintaining data warehouse systems using Teradata technologies. My work focuses on ensuring data integrity and optimizing database performance, which has honed my skills in database management and data analysis. My experience at TCS has equipped me with the expertise to handle complex data systems and contribute effectively to data-driven decision-making processes.

Experience

• ETL developer · TCS11-01-2021

  As an ETL developer, I have honed my expertise using tools like Teradata, IBM DataStage Designer, and Talend to design, implement, and optimize data pipelines. With Teradata, I wrote and optimized complex SQL queries to extract, transform, and load (ETL) data, focusing on query performance, data validation, and resource efficiency. I also handled large datasets, applying advanced techniques such as indexing and partitioning to streamline processing. Using IBM DataStage Designer, I developed reusable ETL components, such as transformer and lookup stages, automated workflows, and performed rigorous testing to ensure data accuracy and integration. I employed parallel processing techniques to optimize performance for high-volume data tasks and maintained robust error-handling processes for seamless operations. With Talend, I addressed modern data integration needs by designing real-time ETL workflows, leveraging its connector library to integrate diverse data sources, and customizing processes for unique requirements. Additionally, I utilized Event Scheduling Processes (ESPs) to automate job execution, manage dependencies, and ensure timely data availability. These experiences enhanced data accuracy, scalability, and operational efficiency, enabling impactful data-driven decisions while ensuring robust and maintainable ETL solutions.
