What I'm looking for

I'm looking to apply Python, SQL, Power BI, and rigorous data-quality practices to automate analysis, improve reporting, and turn complex operational or scientific data into actionable decisions.

I've built automated data pipelines, dashboards, and reporting workflows for operational, environmental, and scientific data. At Pesquera Diamante, I developed Python-based analysis and automation workflows while maintaining Power BI and advanced Excel KPI reporting.

At AtkinsRéalis, I optimized environmental data-processing pipelines with Python, reducing manual analysis time by more than 40%. I also implemented QA/QC processes, integrated structured sources with SQL, and automated project-performance reporting.

My physics background and current M.Sc. studies in Atmospheric Sciences support rigorous statistical analysis, time-series work, and scientific data processing. I've also analyzed atmospheric radar datasets at the Jicamarca Radio Observatory and presented results to an international scientific committee.
