About

As a Power Platform Developer and Business Intelligence Specialist with 5+ years of experience, I transform complex data into actionable insights and automated workflows that drive efficiency and compliance, particularly in healthcare analytics. My end-to-end expertise spans Power BI (DAX, data modeling, and Power Query), Power Apps, and Power Automate, enabling me to build integrated solutions from raw data to stakeholder-ready dashboards and automated processes.

At CeSHHAR Zimbabwe, I architected Power BI dashboards with real-time KPIs, reducing manual errors by 40% and accelerating reporting by 25%. I engineered SQL-based ETL pipelines to automate data cleaning, cutting processing time by 30%, and resolved 500+ annual discrepancies through validation frameworks, ensuring 100% compliance with PEPFAR/Global Fund standards. Leading a team of 15 data officers across 20+ health facilities, I standardized reporting and improved data completeness by 35% in 6 months. My earlier role saw me automate workflows using Power Platform tools, saving 20+ hours weekly across 15+ health programs while maintaining 98% KPI accuracy.

My technical foundation was solidified at Rubiem Group, where I developed dynamic Excel dashboards with VBA automation (reducing reporting time by 35%) and later transitioned to Power BI, designing executive dashboards that optimized project timelines.

  • Power Platform Integration: I seamlessly connect Power BI with Power Apps (for real-time data entry) and Power Automate (for workflow triggers), creating cohesive data-to-action ecosystems.
  • Data Engineering: Proficient in SQL optimization, ETL development, and performance tuning to ensure scalable, audit-ready pipelines.
  • Impact-Driven Automation: I consistently eliminate manual effort, redesigning systems to slash data entry errors by 40% and automating collection/reporting to save hundreds of hours.
  • Leadership & Compliance: Adept at translating business needs into technical solutions while mentoring teams and enforcing regulatory standards (e.g., PEPFAR).

I hold a Postgraduate Diploma in Business Analytics (Eaton, 2023) and am a certified Microsoft Fabric Engineer Associate (2025), complementing my hands-on expertise with cloud analytics and data engineering rigor.

I bridge analytics with action. My solutions don’t just visualize data; they automate processes, enforce governance, and empower teams. In healthcare, this means turning insights into faster decisions, compliant operations, and tangible outcomes like improved patient data integrity.
