Machine learning engineer in Linz, Austria. I work with Python, SQL, FastAPI, Java, RAG pipelines and reporting tools, and tutor machine learning at Johannes Kepler University Linz.
Have a recurring CSV export, manual report or small Python script that needs fixing? I offer clearly scoped projects with reusable code and documented checks.
| Service | Deliverable |
|---|---|
| CSV cleanup | Cleaned output, reusable Python script and a summary of changes |
| File and report automation | A repeatable command, setup instructions and a sample run |
| Python fixes | A targeted fix, an explanation and a check that covers the reported problem |
| API data transforms | A documented transformation from an agreed input to the output you need |
Small projects start at €150. An example scope is one CSV, up to 10,000 rows and 20 columns, with up to five agreed cleanup rules and one revision within that scope. The final price, delivery date and payment terms are agreed after reviewing the requirements; opening an inquiry creates no order or charge.
GitHub inquiries are public. Start with column names, made-up sample rows and the result you need. We can arrange an appropriate private channel before exchanging real files.
A native macOS app for reviewing CSV cleanup changes before exporting a separate copy. It handles delimiter choices, whitespace, blank records and exact duplicates while keeping cell values as text.
The example above uses fictional data. It preserves leading-zero IDs, decimal commas, quoted text and a multiline cell. See the example and validation.
Release status: version 1.0.0 has been submitted to Apple for review. It is not yet available to purchase. Support and privacy information.
My professional experience includes machine learning engineering and data science at Metamagix, data analysis at DIAGEO, and machine learning tutoring at JKU Linz. I hold a BSc in Artificial Intelligence and a BSc (Hons) in Corporate Finance, and am pursuing master's studies at JKU.
I use AI-assisted development, with source review and repeatable checks. Scope and validation are documented with each deliverable.
