Senior Data Engineer
Volvo
3 2021 - Current
- Developed and implemented serverless event-driven data integration in Azure by building real-time data pipeline to expose charging/faults to customers.
- Led development of high-capacity data pipeline using PySpark and Azure Databricks, focused on extracting binary CAN data from vehicles, thereby significantly boosting processing efficiency.
- Built a data orchestration pipeline to extract terabytes of data using Airflow, S3, Spark and Iceberg. Implemented strategic partitions and bucketing to automate signal segregation from 4000 plus parameters reducing more than 50% time in data preparation for analysts.
- Collaborated with system engineers enabling data logging approach by introducing event-based trigger system and created an automated extraction and testing framework using Azure, Databricks and PySpark
- Created a framework to create Data Catalog together with iceberg and python's profiling capabilities to profile the data and merge it with data catalog tool such as OpenMatadata to enable GENAI tasks
- Created a Automated CAN data quality framework using Spark to check value thresholds, nulls, data integrity etc.. Created interactive dashboards with Grafana to display quality metrics and an instant overview on data anomalies which reduced bugs at the early stage of product development.
- Integrated and maintained continuous integration (CI) systems using Jenkins and Azure DEVOPS to automate testing and deployment processes, significantly improving development speed and quality.
- Participated in Stakeholder meetings to create more awareness towards data driven development and align data priorities together with hardware/software development

- Orchestrated setup and maintenance of Hadoop cluster in Windows environment, integrating Hive, Spark, MongoDB, Postgres, Angular, and Python with focus on robust version control.
- Gained hands-on experience with AWS services, especially AWS Kinesis Data Stream and AWS Lambda, including development of scalable Python modules for Cloud Watch metrics integration with Splunk.
- Pioneered HAdeaP (Healthcare ETL Engine) project, patented application (U.S. Patent Application No.: 16/008,602) developed from scratch using Hadoop ecosystem components (HDFS, Spark, Scala, Python, Hive) and D3JS for data visualization.
- Developed and maintained Python Flask-based REST API framework for efficient data fetching and transformation from various sources, including databases and flat files, into Extraction Framework.
- Enhanced data processing capabilities by replacing existing Informatica Framework with Python-based ETL Framework, leading to 30% increase in performance, focusing on MongoDB to SQL Server data transformation.
- Co-developed and partly owned patented Digital Data Assistant (chatbot) using Natural Language Processing and deep learning techniques.
- Modified existing AWS Glue Tables to Delta Tables for optimized merge operations in Hive.
