React

I am a freelance developer in Zaandam, next to Amsterdam, and React is part of frontend: 4 projects since 2016, listed below.

2026 — now ThuiszorgInHolland Employee and client app for a home-care organisation, keyed to AFAS One app for care workers, clients and applicants, with no database of its own: the website is the backend, and who may log in is decided by an hourly sync from the AFAS payroll system.
2025 — 2026 UpLinked UpLinked, an AI LinkedIn content platform rebuilt from Bubble on Convex A LinkedIn writing tool for Dutch entrepreneurs, moved off Bubble onto Convex with six agents, a versioned prompt database, three models writing every post, and 196,000 rows carried across.
2020 — now SPJ Financial & Corporate Communication Website and editorial system for SPJ A bilingual site and headless editorial system for a financial and corporate communications agency, keeping its news, people, services, cases and transaction record in one place.
2016 — 2022 AllMusic Publishing Bubble search, player and CRM for a library-music publisher The website and the back office of a Dutch library-music publisher: a search for people who do not know what to search for, a player that survives navigation, licences paid through Mollie, and a CRM that ran the royalty statements.
