What I'm looking for

I seek roles where I can build and operate scalable data platforms, apply Data Mesh and modern ETL tooling, mentor teams, and deliver high-quality analytics products.

I am a Senior Data Engineer with extensive experience designing and supporting scalable data platforms in financial services and asset management. I specialize in Snowflake, dbt, and AWS-based data pipelines and have delivered domain-oriented data products using Data Mesh principles.

My work spans building ingestion and transformation pipelines (Lambda, S3), orchestrating workflows (Airflow, Step Functions), and implementing analytics solutions and dashboards. I have led ETL development with Talend, Informatica, and delivered automated pipelines to production while providing monitoring and production support.

I am results-driven, focused on data quality and operational reliability, and experienced in mentoring teams, product ownership for data tools, and producing POCs that improve analytics engineering and reporting outcomes.
