FAQ
Can you work in MATLAB instead of Python?
Yes. I can clean, prepare and analyze datasets entirely in MATLAB if required.
Can you look at my data before I order?
Of course. Send me your file or a sample, and I’ll tell you which package fits best.
What file formats do you accept?
CSV, Excel, JSON, SQL exports, MAT files, TXT, and many more.
Can you handle large datasets?
Yes. My Premium package supports large or complex datasets and includes advanced preparation.
Will I receive the code?
Yes. Source code is included in Standard and Premium. You can also add it as an extra to the Basic package.
What if my data is very messy or inconsistent?
No problem. I specialize in fixing messy data and can provide a data quality report if needed.
Can you prepare data for machine learning?
Yes. I can create clean, structured, ML-ready features in Python or MATLAB.
Do you sign NDAs?
Yes. I treat all data as confidential and can sign an NDA upon request.
