I will clean, automate, and engineer your messy data pipelines
Over deze dienst
Tired of manually fixing messy Excel files or struggling to format raw data for Power BI? Welcome to your complete data engineering solution. As a Data Science student at NSBM Green University with a background in software engineering, I dont just edit cells. I use a custom, high-performance Python engine to programmatically clean and structure massive datasets in seconds.
What My Data Engine Does:
- Automated Cleaning: Impute missing values, remove duplicates, and handle outliers.
- Standardization: Fix text formatting, date parsing, and naming conventions.
- Data Auditing: Get a transparent report of every change made.
- Advanced Modeling: Convert flat files into Star Schemas for Power BI.
- Developer Assets: Generate SQL dumps and live Python FastAPI servers.
Why Choose Me?
I bridge the gap between business needs and technical execution. Whether you need a pristine Excel report, efficient BI models, or deployable code, I apply rigorous academic standards to real-world problems.
Please message me before ordering if your dataset is highly complex or requires web scraping!

Veelgestelde vragen
My file has hundreds of thousands of rows. Can you handle it?
Yes! My automated pipeline is built on Polars, an ultra fast data processing library in Python. It can handle massive files up to 1,000,000+ rows effortlessly and much faster than standard Excel or Pandas.
What is a Power BI Star Schema and why do I need it?
Importing massive flat files slows Power BI. I'll engineer your data into a "Fact" table with surrounding "Dimension" tables. Power BI will automatically detect these relationships, saving you hours of manual modeling and ensuring your dashboards run at peak performance.
What is the Headless API package in the Premium tier?
This is for software developers. Instead of giving you a static Excel file, I package your clean data into a fully functional FastAPI web server. You just unzip it, run one command, and your data is instantly available as a live JSON web feed for your front end applications.
Do you provide proof of the data cleaning?
Absolutely. Every delivery includes a Data Audit Report. This summary shows exactly how many original rows you had, how many were dropped due to critical errors, and the final row count, giving you complete confidence in the data.
Can you help me put the clean data back into my own database?
Yes, if you select the Premium package, I will generate a complete SQL Database Dump. You will receive a .sql file containing all the exact CREATE TABLE and INSERT INTO commands needed to populate your database instantly.
