Dolores P.

I'm a data analyst and R/Shiny developer with 3+ years of experience building analytical applications, integrating large datasets, and automating reporting. I help teams work through data problems that make reporting difficult: inconsistent figures, duplicate records, incompatible files, and unclear KPI definitions. I investigate the causes and build practical tools with checks that make the results easier to verify. * Recent projects: - Healthcare Analytics: Built an R/Shiny application for a multi-location dental group, bringing together patient, appointment, procedure, and financial data. Investigated conflicting reports, clarified metric definitions, and implemented validation checks so the team could review activity across locations. - Financial Reconciliation: Developed an R/Shiny tool to compare bank statements with accounting ledgers. Standardised different file formats, prevented duplicate transaction matching, and made discrepancies easier to investigate through traceable Excel outputs. * What I can help with: - R/Shiny dashboards and interactive applications - Large dataset preparation and multi-source integration - Data reconciliation, KPI validation, and troubleshooting - Data visualization and automated reporting - Improving existing R/Shiny applications * Tools: R, Shiny, tidyverse, ggplot2, plotly, R Markdown, SQL, and Excel. I ask questions early, explain my findings, and document the decisions behind the results so your team can review and reuse the work. Tell me what you're trying to understand, automate, or improve and we can agree on a focused first milestone.
