Self-initiated product work. I built and published a deterministic auditor for public RSS, Atom, RDF/RSS, and JSON Feed endpoints.
It records delivery and redirect evidence, parsing, required fields, dates, freshness, duplicates, entry limits, cache validators, normalized entries, and explicit pass, fail, or unknown outcomes.
The Actor is live on Apify with bounded pay-per-event execution and public task examples. Owner verification runs are not represented as customer demand or revenue.
