Firebase

I am a freelance developer in Zaandam, next to Amsterdam, and Firebase is part of backend and data: 3 projects since 2020, listed below.

2023 — now SUYE Certificates of originality on Ethereum and Polygon for an art studio A platform where an art studio and its artists deploy an ERC-721 contract per collection or per certificate, without holding any crypto themselves, and drop the mint button, the certificate wall and the token gate into their own websites.
2021 — 2026 Taxi Haarlem Service Dispatch system and customer app for a taxi cooperative Everything a thirteen-driver Schiphol taxi cooperative runs on: the website, the app, the booking form, the dispatch board, and a Google Calendar that had to stay the boss of all of it.
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.

Also in backend and data

Tell me what you want to build, what already exists and where you are getting stuck.
