About this Gig
Drowning in raw data but starving for insights? Let me transform your messy datasets into interactive visual stories that drive revenue.
As a business-minded Data Analyst, I specialize in building end-to-end analytical pipelines. Whether your data is stuck in CSV files, SQL databases, or scattered Excel sheets, I clean it, find hidden trends, and deliver executive-ready dashboards.

FAQ
What data sources and file formats can you work with?
I work with a wide range of formats including Excel files (.xlsx, .xls), CSVs, text files, and SQL database dumps (MySQL, PostgreSQL, MS SQL Server). If your data is hosted on a cloud platform, you can securely share access or export sample tables for me to build your pipeline.
Do I need to have my data perfectly organized before sending it to you?
Not at all! In fact, data cleaning and transformation are a major part of my service. I will handle the deduplication, fix missing or broken values, merge separate tables, and structure your raw data so it is perfectly optimized for analysis and dashboarding.
Will I receive the raw source files after the project is complete?
Yes, absolutely. You will receive full ownership and all source files upon delivery. This includes your fully functional Power BI desktop files (.pbix), organized Excel sheets with dynamic pivot tables, or the optimized .sql scripts used for your database queries.
My data contains confidential business information. Can you sign an NDA?
Yes, data security and confidentiality are my top priorities. I am completely open to reviewing and signing a Non-Disclosure Agreement (NDA) before you share any internal datasets or system credentials with me.
Can you update the dashboard automatically when my data changes in the future?
Yes. I build dashboards using Power Query in Excel and Power BI, meaning the data structures are dynamic. Once the initial setup is complete, you can simply refresh the data source, and all charts, KPIs, and visual elements will update automatically.
