I offer AI-assisted Python automation and CSV/Excel data cleanup. I agree on a clear scope, build reproducible solutions, test failure cases, and provide readable code and handover notes. My demonstration work includes a Python API reliability helper with 18 passing offline tests and a synthetic spreadsheet cleanup example. These are samples, not previous paid client projects. I clearly distinguish local tests from live integrations. For an existing script, I review the supplied code, expected output and acceptance criteria before confirming scope and delivery. Please remove passwords, API keys and other secrets from any examples you send.
