Data and document automation. I turn messy CSV, Excel and PDF tables into clean, schema-validated output: deduplication, type and date normalisation, validation reports, and small Python/Node CLI tools you can re-run yourself. Typical work: CSV to formatted XLSX, PDF table extraction, data-quality checks, Telegram/Discord bots and scheduled scripts. Fixed-price milestones, plain-English scope stated up front, source code and a README delivered with every job. Work is AI-assisted and reviewed before delivery.
