What I'm looking for

I seek a collaborative, agile team role building scalable Big Data pipelines and cloud-native data platforms that enable analytics, reduce costs, and deliver real-time insights.

I am a Data Engineer with 2.8 years of experience in the automotive industry, focused on designing scalable data architectures and processing connected vehicle data to drive customer engagement and cost reductions.

At Tata Technologies I delivered production Big Data solutions using PySpark, Hive, Airflow and AWS EMR, processing terabytes daily and improving operational efficiency and reporting accuracy across teams.

My technical strengths include building and optimizing ETL pipelines, tuning Spark jobs with partitioning and caching, and centralizing data from HDFS, S3, MongoDB and Kafka to boost analytics productivity.

I value collaboration, mentorship, and agile delivery; I aim to apply practical engineering and data-driven insights to reduce costs, speed processing, and enable real-time decision making via APIs and dashboards.
