What I'm looking for

I'm looking for remote EU opportunities in analytics engineering, data quality, data operations, or SQL-focused analytics workflows, where I can build reliable datasets, automate validation, and support dependable reporting.

At Mercer, I've owned data quality and validation for recurring North American HR-data projects valued at approximately $260K annually. I design SQL-driven transformations, schema mappings, duplicate detection, consistency checks, format validation, and outlier identification to turn production data into reliable reporting datasets.

I've automated repetitive checks with R and R Shiny, saving approximately 300 hours of manual review each year, while supporting reproducible Word-to-PDF and Excel reporting pipelines. I'm now expanding into analytics engineering through hands-on work with PostgreSQL, dbt, and modern data workflows.
