    I want a sleek, self-refreshing Power BI dashboard that pulls customer counts from two sources—an Excel file and our Databricks environment—and visualises the 12-month trend for each line of business across Brand A, Brand B and Brand C. The core visual should be clean line charts with a rolling monthly view, allowing users to toggle brands or drill down by product line without losing the last-year perspective. You will work with my existing Databricks SQL endpoint (I’ll share the cluster URL and credentials) and a locally stored Excel workbook. I need the model set up so both sources refresh automatically through the Power BI gateway and any new month appended to either source rolls straight into the visuals.

    Our in-house document management platform has been running smoothly on a C#/.NET stack, MS SQL Server, and AWS for several years, but the developer who built and nurtured it is leaving. I need someone who can step in right away, understand the codebase, and keep the application stable and performant. The immediate focus is routine maintenance—diagnosing and fixing any bugs that surface and squeezing better performance out of the code, database, and AWS resources. I don’t have a current list of issues, yet I suspect the usual mix of edge-case errors and slow queries will emerge once you start profiling the system.

Almost every system these students build or support will store its data in a relational database, and almost every serious production incident involves one. From what a database is for through querying, joins and aggregation to schema design, transactions and indexing. Real time goes to reconciliation - checking that a query returned the RIGHT answer rather than a plausible one - because a wrong number delivered confidently is worse than no number at all. Note: this course shares ground with DB-101, the Databases track foundation, at a much shallower depth.
