Adrian Espinoza

I am a bilingual data analyst focused on data validation, statistical analysis, and automation, with experience delivering measurable improvements in data quality.

At Petroperú, I built automated Python and R data-cleaning scripts that reduced errors by 30% and created dashboards and reports to monitor KPIs.

As an independent developer I designed a cryptocurrency trading bot using multi-indicator strategies and machine learning, and a poker bot employing counterfactual regret minimization and rigorous statistical testing.

I routinely use Python, R, SQL and Google Sheets to automate data cleaning, detect anomalies, optimize processes and ensure compliance, bringing strong attention to detail and bilingual communication to every project.
