If your Python or data script used to work but now breaks, gives wrong results, or behaves inconsistently — I can help. I specialize in debugging, fixing, and stabilizing existing Python and data-processing scripts, especially those dealing with real-world, messy data. I’m not focused on flashy demos or rewriting everything from scratch. My goal is simple: make your existing code reliable and correct. What I typically help clients with: * Fixing errors in existing Python scripts * Debugging Pandas / NumPy data issues * Cleaning and validating CSV, Excel, JSON, XML, HTML, or text data * Correcting logic bugs in AI-generated or legacy code * Data transformation and ETL-style processing * Making scripts work properly on Linux environments I have 11+ years of professional experience in data engineering / ETL, and 5+ years using Python for real production problems . I’m comfortable working with complex data formats (including fixed-length, multibyte, and legacy files) and minimal documentation. Clients usually come to me when: * “The code almost works, but something is wrong” * “The output doesn’t match expectations” * “AI generated this, but it fails in practice” * “I need a careful fix, not a risky rewrite” What you can expect from me: * Clear communication * Minimal, safe changes * Honest feedback if something is not worth fixing * Code that works in your setup, not just mine I work best on clearly defined debugging, fixing, or data-cleanup tasks, either fixed-price or short engagements. If you can describe the issue and share the code or data, I can usually tell you quickly whether I can help.
