Über diesen Service
Do you have data scattered across CSV files, Excel sheets, or APIs that needs to end up in a database?
I build Python ETL pipelines that extract, clean, validate, and load your data into PostgreSQL so you can query it in seconds instead of copying rows by hand.
WHAT YOU GET
Extraction from CSV, Excel, APIs, or Google Sheets
Cleaning: duplicates removed, types fixed, missing values handled
Validation with Pandera (schema + business rules)
Fast loading into PostgreSQL using the COPY protocol
Docker setup for reproducibility
Unit tests to make sure it works
Documentation on how to run it
WHY WORK WITH ME
Data engineering graduate (Kielce University of Technology)
Recent project: 9 tables, 1.5M rows, loaded in 40 seconds validated and tested

FAQ
What data sources can you work with?
CSV files, Excel spreadsheets, REST APIs, Google Sheets, JSON exports, and most database exports. If your data lives somewhere else, send me a message — I'll tell you if I can handle it.
Do I need to know Python or SQL?
Not at all. I deliver a working script and clear documentation. You run one command, and it does the rest. If you want to understand what's happening, I'm happy to explain in plain language.
Can you clean data that's already messy?
Yes — that's most of the work. I remove duplicates, fix date and number formats, handle missing values, and standardize text. You get a clean, validated dataset at the end, plus a short report of what was changed.
What if I don't know which package to choose?
Send me a message with a short description of your data before ordering. I'll tell you honestly which package fits — or if none of them do, I'll say that too.
How do you handle my data? Is it safe?
I only use the files you share for the duration of the project, work in a local environment (no third-party uploads), and delete everything after delivery unless you ask me to keep it. I'm happy to sign an NDA if your data is sensitive.
