What I'm looking for

I seek a role building scalable data platforms and event-driven pipelines, emphasizing automation, performance optimization, and collaborative delivery.

I am a Senior Data Engineer with seven years of experience designing and delivering scalable ETL/ELT pipelines, event-driven architectures, and data platforms across Azure and Databricks.

I focus on performance optimization, data quality, and reliability, having reduced processing times from hours to minutes and enabled near-real-time workflows through event-driven designs.

My hands-on technical work spans Python, Spark, SQL, Airflow/ADF, Databricks, Delta Lake, and process automation, and I have implemented data quality frameworks, automated ingestion from APIs and SFTP, and resolved production stability issues.

I collaborate through code reviews and CI/CD practices, build monitoring and validation scripts, and deliver business impact such as improved reporting timeliness and millions in realized value.
