Project case study
Power BI Analytics Dashboards
Cleaner analytical storytelling for teams that need to understand raw numbers quickly.
Problem
Business intelligence dashboards that translate noisy datasets into decision-friendly visuals and operational views.
Context
A set of business-intelligence exercises focused on turning source data into decision-oriented Power BI views using SQL, Excel, and visual analysis.
My Role
AI/ML Engineer, Data Systems Builder & Motion UI Developer
Contribution
- Prepared source data for dashboard analysis with SQL and Excel-based cleaning steps.
- Organized Power BI report views around comparisons, trends, and operational summaries.
- Applied responsive visual hierarchy so the most important analytical signal remains readable first.
Architecture
Source data
Provides the raw tables and spreadsheet inputs used by the analysis.
Feeds Transform layer
Transform layer
Cleans and reshapes source fields with SQL and spreadsheet tooling.
Feeds Analytical model
Analytical model
Organizes measures and relationships for report consumption.
Feeds Power BI report
Power BI report
Presents the decision-oriented charts and summaries.
Terminal stage
Engineering Decisions
Separate source preparation from report presentation
Reason: A clean analytical model keeps visual pages focused on interpretation instead of repair work.
Tradeoff: Changes to source fields must be propagated through the transform and model layers.
Prioritize a small number of decision signals per view
Reason: Dense dashboards make it harder to identify the first useful comparison.
Tradeoff: Secondary detail moves to supporting pages or drill-down views.
Outcomes
Made complex data easier to compare, read, and act on through stronger dashboard structure and clearer visuals.

Limitations
- No public dashboard file, source dataset, or quantified business outcome is linked.
- The linked Power BI learning record supports training context, not a claim of production deployment.
