I build and ship automation tools end to end: web scraping pipelines that collect from multiple public sources, clean and de-duplicate the data, and deliver it as clean CSV files with HTML reports and raw-data evidence. Recent builds: • A job-market dataset pipeline: 3 public sources → 335 clean rows, a documented exclusion policy, deterministic re-runs (same input, byte-identical output), plus an 18-second walkthrough video. • A document Q&A tool that answers from a private document set and cites the source of every answer. • An n8n automation that runs a multi-step workflow end to end. I work code-first: every build ships with the working files and short documentation, so clients can run it themselves. I test every automation before delivery.
