Independent analytics & BI consulting
Clear reporting starts with numbers that hold up. I help you resolve reporting gaps, build useful dashboards, and simplify the work behind them.
Built around your reporting environment
Consulting services
You may need a new dashboard. You may need to fix the report you already have. The first step is understanding the problem.
When the numbers do not agree.
Trace the differences back to their source. Review calculations, definitions, and data quality so your team knows what needs correcting.
Findings, metric definitions, and a prioritized correction plan.
Review my reportingWhen performance is hard to see.
Build a focused view of the measures your team uses to run the business, with enough detail to investigate a change and understand its cause.
A Power BI, Tableau, or Excel dashboard with documented calculations.
Discuss a dashboardWhen preparing the report takes too long.
Simplify recurring Excel and SQL work. Replace avoidable manual steps and build in checks before the next reporting cycle.
A revised workflow, reconciliation checks, and refresh instructions.

01 / Excel reporting · Fictional data
Duplicate orders, cancellations, and missing costs can distort a sales report. This workbook preserves the source records, makes exclusions visible, and calculates five KPIs from the same eligible orders.
Independent demonstration using fictional data; not a client engagement or evidence of commercial results.
The complete demo kit (ZIP) includes source data, a practice export, and refresh instructions. The workbook supports up to 300 rows of 2026 order data.
Calculations and replacement-export tests passed in the authoring engine. Native Microsoft Excel verification remains outstanding; use the practice export before adapting the workbook.
Open the full case study 02 / Tableau dashboards · Synthetic data
Seven dashboards bring revenue, acquisition, releases, availability, and application performance into a consistent reporting system. Monthly comparisons show what changed; supporting views explain the movement.
Independent demonstration using synthetic startup data; not a client engagement or evidence of commercial results.
The case study includes seven native dashboards, 70 editable Tableau worksheets, screenshots, and reuse instructions. Data covers March through August 2026.
Monthly headline values and revenue and waitlist bridges were reconciled against the synthetic source data. This demonstration has no live data feed or production alerts. Replacing data requires regenerating the supporting extracts and validating the resulting workbook.

David’s project portfolioWorking together
You should know what is being built, how it will be checked, and what your team will need to maintain it.
We discuss the decisions your report supports, who uses it, and where the current process falls short.
I propose the scope, fee, and schedule. We agree on definitions and checks before I build or revise the report.
We review the output against the scope. You receive the files, relevant documentation, and a walkthrough.
Work directly with the person responsible for the report.
Bold Proof Analytics is my independent consulting practice. I work across reporting, dashboards, data quality, and operational analysis using Excel, SQL, Power BI, and Tableau.
I pay attention to the details that determine whether a report earns its place: what the measures mean, whether the numbers reconcile, and how the next person will maintain it.
Before we begin
Yes. An existing spreadsheet, dashboard, or recurring report is a useful starting point. We can focus on the definitions, calculations, layout, or refresh steps that need attention.
I review the reporting need, data sources, and expected output before proposing a fee and schedule. The proposal sets out the deliverables and exclusions; any change in scope is discussed before additional work begins.
We start with the tools you already use. If a different tool is needed, we discuss the reason, licensing, and ongoing cost before including it in the scope.
Yes. Project discussions, reviews, and handover can take place remotely. We agree on meeting times, communication, and data access at the start.
Send a brief description of the reporting problem, your current tools, and any deadline. Leave confidential files and personal data out of the first email; we can agree on an appropriate way to share data after discussing the work.
Let’s talk
Tell me what your reporting needs to do, where it falls short, and when you need it. I’ll follow up to understand the scope and whether I can help.
