FAQ
Can you fix my script or bug within 24 hours?
Yes! For the Basic package, I usually deliver within a few hours if the bug is clearly defined and I have all the necessary access. Please message me first to confirm my current availability.
Do you provide the source code and documentation?
Absolutely. You will receive the full source code with comments. For Standard and Premium packages, I also include a README file with instructions on how to install and run the script using Python or Docker.
What information do I need to provide to start?
To start quickly, please provide a clear description of the task, the existing code (if any), and any API keys or login credentials required for the integration. If it's a scraping task, please provide the target URLs and the required data fields.
Can you handle large-scale data processing?
Yes. I use Polars, a high-performance data processing library, which allows me to handle millions of rows much faster than traditional libraries like Pandas. If you have "heavy" CSV/Excel files, I’m your guy.
What happens if the code stops working after the order is completed?
I ensure my code is robust before delivery. However, if a bug is found within a week of delivery that was part of the original scope, I will fix it for free. Note: This does not cover changes in third-party website structures (for scrapers) or new feature requests.
What is included in your "Task Automation" service?
Everything that replaces manual work: Web: Auto-filling forms or actions via Selenium/Playwright. API: Connecting Shopify, Stripe, Google Sheets, or REST APIs. Local: Auto file/PDF processing and CLI tools. Deploy: Scripts running 24/7 on servers via Docker.
