With over 15 years in business intelligence and analytics, I’ve led teams, built systems, and architected solutions that power decisions across industries. My background spans deep BI strategy, scalable data pipelines, AI integrations, and platform innovation—all grounded in real-world constraints.Today, I channel that experience into building modular, ethical, and human-centered tech. Whether it’s an AI-driven platform, a home-lab architecture, or a BI refactoring tool, my approach is the same: solve real problems, build for scale, and make it sustainable.Let’s connect if you’re building systems that work—and want a partner who’s done it before.

   I lead analytics delivery and BI modernization for business-critical reporting and decision support. I partner with business leaders and Enterprise Data/IT to define KPI strategy, own data quality end-to-end, translate complex issues into clear actions, and drive execution through a consistent operating cadence (intake → build → validate → release). I set priorities, unblock delivery, and coach teams toward business-first outcomes while balancing speed, reliability, and governance.Technical focus: Power BI (Fabric capacity, semantic models, paginated), Snowflake, JD Edwards E1, Essbase/Hyperion, Amazon Athena; dbt + GitHub; Airflow coordination; ServiceNow workflows; dimensional modeling, KPI design, documentation/standards, prod/non-prod governance, performance tuning, refresh and capacity optimization.Selected impact:• Ensured reporting continuity through the E1 migration—established backup/test patterns, coordinated UAT + hypercare, and remediated issues to protect critical KPIs.• Delivered time-sensitive goals with consistent execution; managed late changes professionally; recognized for “Raises the Bar” leadership and reliability.• Modernized legacy reporting—expanded scope (community lens, snapshot views) and strengthened validation/visualization with Finance partners.• Advanced investor/pricing analytics—evolved inventory bid logic and tightened governance to support high-volume cycles while safeguarding compliance.• Accelerated team transformation—aligned with Enterprise Data on tooling/ways of working; instituted Fabric/Power BI governance and reduced technical debt.Known for calm, high-ownership leadership, cross-functional partnership, and modernization tied to measurable business outcomes.
