You will get Your raw data cleaned and an automated Looker Studio dashboard
Project details
Stop struggling with messy spreadsheets. I turn raw, ugly data into clear, interactive insights. Most data analysts simply drag and drop your files into a chart. The problem? If your dates are wrong, your duplicates are hidden, or your formatting is inconsistent, your dashboard will be inaccurate.
I am a Data Systems Specialist with a background in large-scale Health Data. I don't just visualize your data; I sanitize it first using custom code.
My Process:
• Validation: I review your raw files (Excel, CSV, G-Sheets, or JSON) to catch hidden errors.
• Sanitization: Using custom scripts (Node.js or Google Apps Script), I fix formatting issues, remove duplicates, and standardize your data structure.
• Visualization: I build a professional Google Looker Studio dashboard that tells the story behind the numbers.
What you get:
• A "break-proof" dashboard that handles future data updates gracefully.
• Clear metrics (Trends over time, aggregation, category breakdowns).
• Documentation on how to maintain your report.
Don't let bad data ruin your decision-making. Let's build a source of truth you can trust

Abuja, Nigeria - 9:48 pm local time
As a Data Systems Specialist with extensive experience in Global Health (DHIS2) and eCommerce, I specialize in fixing messy datasets, migrating legacy systems to modern architectures, and building automated dashboards that actually work.
How I can help you:
1. Data Migration & Cleanup: Moving from Excel/MySQL to PostgreSQL? I write custom Node.js/SQL scripts to validate, sanitize, and migrate your data with 0% loss. (Ask to see my Data Sanitizer Tool on GitHub, built specifically for GDPR-compliant PII masking).
2. Complex Dashboarding: I move beyond basic VLOOKUPS. I build Google Sheets/Excel systems with Apps Script automation to track inventory, run rates, and sales forecasting in real-time.
3. Technical Troubleshooting: If your API isn't syncing or your database queries are timing out, I can diagnose the bottleneck and optimize your schema for performance.
Tech Stack:
Languages: SQL, JavaScript (Node.js, Apps Script), Python
Databases: PostgreSQL, MySQL, DHIS2
Tools: Postman, Git, Excel/Sheets
I am available for urgent fixes and long-term architecture planning. Let's clean up your data.

Data Audit & Sanitization
I review your raw files for errors. Then, I run my custom Node.js script to fix formatting issues, remove duplicates, and standardize the data structure.
Dashboard Construction
I connect the clean data to Looker Studio, create the calculated fields (formulas), and build the visual charts and graphs.
