What I'm looking for

I’m looking for a team that values Azure-first data engineering, reliable MLOps/GenAI delivery, and measurable data quality. I want to build end-to-end pipelines with strong monitoring, automation, and mentorship to drive real outcomes.

I’m a Senior Data Engineer with 10+ years across banking, big tech, and insurance, specializing in Azure data platforms, MLOps pipelines, and ETL/ELT engineering. I focus on turning messy operational reality into reliable data products that teams can trust.

At AXA, I shipped a GenAI application for claims handling and helped build an MLOps pipeline that enables early claim settlements and cost savings. I also designed and deployed 20 production Azure Data Factory (ADF) ETL/ELT pipelines with automated data quality checks, achieving a 100% data quality pass rate across nightly batch runs.

I lead technical mentorship for a Data Engineer and support an intern building unit tests for the pipeline. I’m committed to an end-to-end engineering mindset—model versioning, automated training, deployment, and monitoring—so ML keeps working as conditions change.

Earlier, I improved data-driven decisions as a Data Analyst at Huawei and delivered automation that gave teams centralized operational visibility. Before that, I built revenue-impacting data workflows at Itaú Unibanco and modernized ETL processes by orchestrating loads into AWS data infrastructure, combining performance with maintainability.
