   Health Data & Systems Support

   Health Management Information System (HMIS)

   • Designed, debugged, and optimized a multi-stage T-SQL reporting pipeline (15+ staged tables) for a national PrEP (HIV Pre-Exposure Prophylaxis) program, integrating enrollment, follow-up, ART, medication, adverse-event, and population-classification data into a single clinical report.
   • Diagnosed and resolved structural SQL Server errors and corrected underlying clinical business logic (PrEP eligibility, ART status, stop reasons, seroconversion tracking).
   • Improved report runtime by eliminating redundant query branches, adding targeted indexes on staging tables, and replacing a row-by-row scalar function with a set-based equivalent.
   • Collected, cleaned, and validated data from electronic health records and other health systems to ensure accuracy, consistency, and completeness.
   • Built dashboards, charts, and reports in Excel and Power BI to present findings to healthcare providers and administrators; tracked public-health trends including disease outbreaks, vaccination rates, and population health metrics.
   • Used DHIS2 dashboards to review and validate regional health data as part of routine data quality checks.
   • Provided first-line (Tier-1) technical support, diagnosing and resolving hardware, software, and system-related issues for end-users.
   • Installed, configured, and maintained workstations, printers, routers, switches, and access points.
   • Monitored LAN/WAN connectivity and system performance, and managed user accounts, access permissions, and IT asset documentation.
   • Implemented file-sharing and backup systems for data availability and recovery, and maintained documentation of configurations and procedures.
   • Supported staff on digital health systems and collaborated across facilities to deliver timely IT infrastructure solutions.

   Personal projects using SQL, Excel and Tableau

   • Built an Excel dashboard for a pizza sales dataset (48,620 order lines, 21,350 orders, about $817,900 in revenue) using PivotTables and KPI measures, covering daily and hourly order trends, category and size share of sales, and best and worst sellers.
   • Cleaned and analyzed 1,000 bike-buyer records in Excel, adding age brackets and building PivotTables and a dashboard that show how income, age, gender and commute distance relate to purchases.
   • Ran exploratory analysis of an e-bike sharing dataset (15,000 trips, 25 stations, 1,000 users) in SQL Server using T-SQL, CTEs and window functions, covering peak hours, member vs. casual behavior, station popularity, net flow imbalance and user growth.
   • Built an interactive Tableau dashboard analyzing COVID-19 trends from public datasets.
