- Swiss B permit / Portuguese (EU) citizen — "no work permit required" was wrong, Switzerland is not in the EU - Correct EDGE Empower and prior-role dates - Add Rodado (~730 Brazilian public datasets, 1TB Parquet, DuckDB, NL-to-SQL over MCP) alongside the existing HelvetiScan mention - Drop Java from the skills line — the scraper itself filters Java roles via JAVA_TITLE_RE, so listing it as a skill was inconsistent
