SUMMARY I help operations teams turn messy data and undocumented processes into measurable performance gains. With 6+ years as a Process Engineer in regulated industries (pharmaceutical manufacturing, energy, beverages), I combine Lean Six Sigma Green Belt methodology with Power BI development to deliver business-ready solutions, not just technical deliverables. What I deliver: - Interactive Power BI dashboards with clean DAX, Power Query, and scalable data models - Standard Operating Procedures (SOPs) digitized for QMS environments, with annotated screenshots and version control - Process maps and DMAIC-driven improvement projects with documented ROI - KPI tracking systems that surface waste, downtime, and cost-reduction opportunities Selected results from past projects: - Reduced material waste from 12% to 9% on a pharmaceutical syringe forming line using DMAIC methodology - Cut data processing time by 25% by automating fragmented spreadsheets into a Power BI environment - Achieved 92% audit compliance and zero rework incidents after standardizing administrative SOPs - Maintained 100% vendor accuracy across multiple high-voltage infrastructure projects with tight budgets Tools I work with daily: Power BI · DAX · Power Query · SQL · Minitab · Python · Notion · Visio · MS Project · Excel · Google Sheets Certifications: Lean Six Sigma Green Belt (IBM) · Project Manager (IBM) · Scrum Fundamentals · Power BI Daxus LATAM · Statistical Process Control (IBNORCA) Native Spanish, fluent written English.
