Led the analytics side of a data-center and SAS exit at a major financial institution — 300+ business reports migrated to modern platforms with zero reporting outages, across systems spanning Salesforce, payments, and application-processing modernization. Each cutover ran as a cross-functional squad: report owners, data engineers, and analysts pulled in for the life of the project and coordinated across teams and departments, without being their line manager. Impact assessment, dataset redesign, and cutover sequencing kept every report live — alongside a steady run of smaller migrations, 2–15 reports each.

Owned the migration of a data department’s entire 2,000-repository GitHub estate from self-hosted servers to the cloud — without sitting on the platform team. Built a custom script to back up, standardize, and migrate every repo, set the standards for the new environment, and ran onboarding for new hires, so teams stayed productive throughout.

A Google Apps Script build that removed ~50 hours a month of manual spreadsheet prep across banking teams, plus Python automation for risk-assessment QA that saved roughly 20 hours each quarter. Both run without maintenance overhead.

Time-series sensor analysis at a global mining company. A custom Python model outperformed the vendor’s linear regression by 30%. We also replaced manual Excel planning with Power BI + SQL Server — roughly 100 hours saved per quarter.
