What I'm looking for

I seek a data-focused role where I can apply Python/R and ETL skills to streamline processes, improve decision-making, and grow with a collaborative team.

I am an actuarial science graduate with practical experience applying Python, R and ETL techniques to improve data workflows and decision-making.

At Think Ortegia I processed market-research data using Askia and Excel, optimized legacy codebases, and designed customized reports that improved business insight.

In insurance roles at Britam and Fidelity Shield I supported claims and accounts processes—streamlining reconciliations, improving customer satisfaction, and automating routine tasks to boost efficiency.

I combine analytical rigor, strong office administration and cross-functional collaboration to deliver reliable results and scalable process improvements.
