Results-driven Data Engineer with 5.5 years of experience.
IndiaWhat I'm looking for
I am a passionate Data Engineer with over 5.5 years of experience in developing and maintaining big data projects. My journey began with a strong educational foundation, earning an MTech in Data Science and Engineering from BITS Pilani, where I graduated with a CGPA of 8.69. I also hold a BE in Electrical Engineering from Dr. D. Y. Patil Institute of Technology, Pune, with a CGPA of 8.32. My academic background has equipped me with the skills necessary to leverage data effectively to drive business insights and support strategic decision-making.
In my current role at Citi Bank, I have taken on significant responsibilities, including gathering requirements, designing, and developing ETL pipelines for both structured and semi-structured data using technologies like Pyspark and Scala. I successfully optimized Spark jobs, achieving a 40% reduction in data processing time, and implemented data quality checks that reduced job failures by 20%. My previous experience at Infosys further honed my skills in data transformation and visualization, where I developed impactful dashboards in Power BI and ensured the timely completion of batch processes.
