Manuel M.

I am a Clinical Data Manager and healthcare data analyst with more than 10 years of experience cleaning, normalizing, reconciling, and validating complex datasets. I work with Excel, CSV and delimited files, R, SQL, and clinical research databases to identify missing values, duplicates, inconsistencies, outliers, and cross-system discrepancies. My experience includes preparing data for import, validating data after ingestion, documenting transformation rules, generating quality-control reports, and communicating findings to clinical, technical, and nontechnical stakeholders. I previously managed data from approximately 90 clinical and real-world studies, including more than 35 million data points across 60,000 subjects. Core skills include data cleaning, ETL, reconciliation, data-quality assurance, Excel, R, SQL, healthcare data, workflow documentation, and process automation.
