As a Senior Data Analyst, I’m pivotal in establishing and maintaining a centralized source of data for real-time analysis, enabling actionable insights for service improvements.

BI Developer Dec 2021 - Feb 2024
Cruise.co.uk, Redditch, England

I specialize in creating and implementing comprehensive ETL solutions to facilitate data-driven decision-making. I excel in refining raw data into actionable insights for diverse stakeholders across the organization. Leveraging tools such as Apache Airflow, S3, Redshift, Python, and Looker, I've established robust data pipelines capable of handling 500TB of raw data weekly, significantly enhancing accessibility and analysis capabilities. Additionally, I led a successful migration project from Luigi to Airflow, improving stability, scalability, and scheduling capabilities across 25 pipelines. I've also collaborated with the finance team to automate financial reporting processes, resulting in a notable 10-hour weekly time-saving and enhanced accuracy. Furthermore, I am spearheading the implementation of cruise.co.uk's first Machine Learning project, focusing on developing a Customer Lifetime Value prediction model to inform critical business decisions. Conducting regular training sessions, I ensure stakeholders are adept in utilizing Looker, our Business Intelligence tool, to its fullest potential.
