Why dashboards disappoint

Most dashboards take too long and arrive wrong.

You wait weeks, then spend more weeks on revisions. The numbers don't tie out. The layout buries the answer. By the third draft, nobody trusts the report. There is a better way to do this.

The first draft takes too long.

Before you see anything, someone has to wire the model, write the measures, and lay out the canvas. Most of that is repeated work that should already be solved.

The numbers don't tie out.

One report uses one calculation, the next uses another. Margins drift. Totals disagree. A source of truth that disagrees with itself is not a source of truth.

The story is buried.

A wall of charts is not an answer. If the dashboard doesn't tell you what to do next, you are still doing the analysis yourself.

How I work

Senior judgment, applied the same way every time.

Fourteen years of building dashboards taught me what a good one looks like. A master's in business intelligence taught me why. I bring both to every engagement, and I hold the line on standards an offshore shop or a generic tool can't.

I start from your business question.

Not the data, the decision. Every page earns its place by answering something you actually need to know. If a visual doesn't change what you do, it doesn't ship.

I enforce one set of standards.

Consistent DAX, a clean model, a Z-pattern layout that puts the answer where your eye lands first. Same patterns across every report, so your numbers always agree.

I deliver a file you own.

A real Power BI project. Open it, edit it, version it, hand it to your team. No hosted black box you rent. It is yours from the moment I hand it over.

The unfair advantage

A pipeline I built, working behind every dashboard.

Over fourteen years I built a pipeline that does the repetitive work for me: profiling your data, inferring the model, scaffolding the measures, laying out the canvas to standard. It is deterministic, so the same input produces the same output, every time.

That is why your first draft arrives polished instead of rough, and why I can move faster than a contractor working by hand without cutting a single corner.

Where I've delivered

Fourteen years of turning messy data into the number people trust.

Names stay private. The work is mine, across healthcare, consumer goods, and advertising. Here is the kind of problem I solve.

01
Medical device · commercial ops

Too much inventory, no view of it.

A medical device commercial team was carrying excess inventory and flying blind on where it sat. I built the executive and field-level dashboards that gave them a clear picture, and set the inventory targets they tracked against every week.

02
Global healthcare · enterprise BI

Every team reporting a different number.

At a global healthcare company the leadership team needed one source of truth. I owned the analytics foundation they relied on and set the metric definitions the whole organization reported against, so the numbers finally agreed.

03
National media · marketing analytics

Ad budget spread across channels that didn't pay.

For national media brands I built the dashboards that showed which channels were actually converting and what each conversion cost, so the team could move spend toward the work that performed.

How we work together

Two ways to hire me, depending on the work.

A single dashboard with a clear goal, or an ongoing arrangement where I'm your analytics bench. Tell me the shape of the work and I'll tell you the fit. Rush delivery available when you need it sooner.

Fixed price · per project

One dashboard, one price.

You have a defined need: a report, a source of truth for a team, a one-time build. We agree on scope and a fixed price before I start. No hourly meter, no surprise invoice.

  • Clear scope, clear price, clear timeline
  • Polished first draft, not a rough cut
  • A Power BI file you own outright
Hourly · ongoing

Your analytics bench, on call.

The work is open-ended or evolving: a backlog to clear, dashboards to maintain, analysis that grows as you do. Hourly keeps it flexible while the scope moves.

  • Capacity when your work spikes
  • Consistent standards across every build
  • Senior judgment without a senior salary
Questions before you book

What businesses ask before hiring a Power BI consultant.

How much does a Power BI dashboard cost?

Fixed-price dashboards start at $2,000 for a clean, single-source build, and scale with complexity from there. Multiple data sources, messy integrations, or several connected dashboards cost more. You get the number before any work begins, so there are no surprises. Hourly work runs $125 an hour for ongoing or open-ended scope. See the full Power BI dashboard cost breakdown.

Do you charge fixed price or hourly?

Both, and the right one depends on the work. A defined dashboard with a clear goal is fixed price, so your cost is locked before I start. Open-ended or evolving work, like clearing a backlog or maintaining reports over time, is hourly. On the first call I'll tell you which fits your situation.

How fast can you deliver?

Faster than most, because a pipeline I built over fourteen years does the repetitive setup for me. A standard dashboard turns around in days, not weeks. When you need it sooner, rush delivery is available. The speed never comes at the cost of quality, since the same process enforces the same standards every time.

What makes you different from an offshore developer?

Fourteen years building enterprise BI, an MBA in business intelligence, and time spent leading a 20-person analytics team at a global healthcare company. I start from your business question, not just your data, so you get a dashboard that drives a decision instead of one that is technically correct but unused. You also work directly with the person doing the build, in your timezone. See how a solo senior compares to an agency or offshore freelancer.

Do you work remotely?

Yes. I'm based near Boston, Massachusetts, and work with clients anywhere in the US. Everything runs over call, screen share, and secure file handoff.

Will I own the dashboard?

Yes, outright. You get a real Power BI project file you can open, edit, version, and hand to your team. It lives in your environment, not a hosted tool you rent. Your data stays yours, with zero retention on my side.

What if I'm not sure what dashboard I need?

That is normal, and the first call is built for it. Tell me the business question you're stuck on or the decision you're making blind, and I'll tell you what it takes to answer it. The call is free and there is no obligation.
