Ryan Chen — Python automation and data workflow portfolio

Ryan Chen — Python Automation, PDF & Excel Data Workflow Developer

I build focused, reproducible tools for PDF table extraction, Excel/CSV cleanup, local Python workflow automation, and scoped Python/JavaScript debugging. The public repositories below use synthetic data and are runnable demonstration projects—not client work.

Currently accepting scoped orders on Fiverr. Choose the closest runnable demo below, then use its matching Fiverr link to share representative authorized samples, required outputs, environment, and acceptance criteria.

Tools demonstrated here: Python, pandas, openpyxl, pdfplumber, ReportLab, CSV/XLSX/JSON, JavaScript, unittest, pytest, and Node's test runner.

How I work

Representative authorized sample → confirmed scope and acceptance criteria → implementation → validation → delivery through Fiverr.

What to include in a project brief

  • one representative, authorized sample or a minimal reproduction;
  • the required input and output formats;
  • approximate volume, runtime environment, and relevant software versions;
  • the acceptance criteria and any privacy, OCR, formula, or deployment needs.

For a different but related requirement, contact me through my Fiverr profile. All project communication and payment stay on Fiverr. Please do not send passwords, API keys, private tokens, or data you are not authorized to use.
