Examples
Where this skill appears
Public examples grouped by the kind of technical detail they make visible.
Public case study coming later
Until then, this skill is grounded in production work I can discuss with business-neutral examples while keeping client and employer implementation details private.
Professional context
Where it fits
In telecom analytics and data product work, I worked on enterprise data warehouse architecture, PL/SQL, SQL Server, SSIS, SSAS, and SSRS reporting. The recurring problem was not only moving data; it was making reports reliable enough for people to make decisions from them.
