## About

As a Data Engineer at British Telecom, I’ve found my passion in the intricate dance of big data and real\-time streaming\. Each day is an adventure where I get to design and build scalable ETL pipelines using PySpark and SQL\. It’s thrilling to transform raw data into insights that empower decision\-making across the organization\. My journey started at the Birla Institute of Technology in Mesra, where I first discovered my love for technology and problem\-solving\. One of my proudest achievements has been building ETL pipelines that process over 10 million records daily\. This effort significantly improved data availability for analytics across our teams\. I also had the opportunity to develop real\-time data processing tools during my internship at BT Group, where I created Python scripts that sped up processing times by 30%\. These experiences have not only honed my technical skills but also deepened my understanding of how crucial timely data is for driving business success\. I thrive on challenges—whether it’s optimizing existing systems or diving into new technologies like Kafka and Airflow\. The world of big data is ever\-evolving, and I’m excited to be part of it\. Outside of work, I enjoy exploring new tech trends and participating in local meetups focused on data science and engineering\. If you’re interested in discussing big data solutions or just want to share insights about the latest trends in technology, feel free to reach out\! I’d love to connect over email\. Skills: \- PySpark \- SQL \- Kafka \- Airflow \- ETL Development \- Real\-Time Data Processing
