Firebase developers, security rules first
Launching an MVP fast, or already outgrowing your first setup? Lemon's Firebase developers know both stages, and the price of skipping security rules.

Rules before features

Browse before a brief
Skip the brief if you like: browse Firebase profiles with Node.js, React or Next.js beside it and keep a list of who to meet.

Clear paths to move heavy parts to your own backend when you outgrow it.
