You will get Power BI Data Cleaning and Transformation | Power Query

Project details
Is your Power BI report showing numbers you don't fully trust?
Maybe your data has duplicate records, missing values, inconsistent formats, broken transformations, or refresh errors that keep coming back.
The problem may not be your dashboard.
It may be the data behind it.
I clean and transform Power BI data using Power Query so your reports have a more reliable foundation.
I can help you:
• Clean duplicates and inconsistencies
• Standardize dates, fields, and data types
• Handle missing or invalid values
• Combine compatible data sources
• Fix and improve Power Query transformations
• Prepare data for reliable reporting
• Structure data for future Power BI analysis
Starter: Clean one straightforward Power BI dataset.
Standard: Clean and transform multiple queries or sources.
Advanced: Prepare and structure Power BI data for BI and reporting.
Every project starts by reviewing your Power BI file, data sources, and requirements. I then clean, transform, validate, and deliver the agreed solution.
If you're unsure which package fits your Power BI data, message me before ordering.
**Send me the details of your data problem and I'll recommend the right approach.**

About Eric
Retail BI Analyst | Power BI Dashboards for Better Decisions
Nairobi, Kenya - 9:39 pm local time
Or does your team spend hours combining spreadsheets before every management meeting?
If that sounds familiar, there's a good chance the problem isn't that you lack data.
It's that you don't have one trusted view of the business.
Sales data lives in different spreadsheets. Different teams work from different reports. Numbers don't always match. And before someone can answer questions like:
"Are sales growing?"
"Which stores are underperforming?"
"Which products are driving performance?"
Someone has to manually pull everything together.
Eventually, someone asks:
"Which report is correct?"
And the meeting becomes a debate about numbers instead of a discussion about decisions.
That's the problem I help solve.
I'm Eric, a Business Intelligence & Data Analyst focused on retail reporting, KPI analytics, and business intelligence solutions.
I help retail businesses turn fragmented data into one trusted source of truth so decision-makers can see what's happening, understand performance, and act with greater confidence.
I don't start by asking:
"What dashboard do you need?"
I start with:
"What decisions are you trying to make?"
Because a dashboard can look impressive and still fail the business if it doesn't answer the questions that matter.
My approach is:
Understand the business problem → Define success → Prepare trusted data → Build the reporting solution → Communicate insights → Support better decisions
My experience comes from end-to-end BI case studies and portfolio projects, including the Maven Toys Retail Business Intelligence Case Study, Adventure Works Executive Dashboard, Maven Electronics, and Foodmart Retail BI.
These projects demonstrate how I approach real-world business reporting problems from understanding the business question and preparing data to building models, developing KPIs, creating dashboards, and communicating findings. I present these as portfolio evidence, not client work.
The goal is simple:
Less time chasing numbers.
Less manual reporting.
Better KPI visibility.
More confidence in your data.
Better business decisions.
If your team is spending too much time compiling reports or you're not confident that everyone is working from the same numbers, tell me how you're currently reporting on your business.
We'll start with the reporting problem not the dashboard.
Tools: Power BI, Excel, Power Query, DAX, data modeling, KPI & performance reporting
