Community platforms and SDKs

Plaazaa: a community platform

Plaazaa is a community platform for cities and local businesses. It has Spaces with roles, live chat, problem reports with a map, events, polls, announcements and six languages. I design, extend and run it as a product.

I want to be plain about its base. Plaazaa sits on a third-party engine, which I extend and tune. The demo page says this on the card, and I say it here too. The demo shows a sample town with test accounts, made-up reports and fictional personas only.

If you want a community for a city, a business or a group, this is the kind of system I can build or extend. See the Plaazaa case study.

The apps platform and SDK

Convoy and the Plaazaa games run on a small platform I designed:

• Browser SDK modules. Shared rooms, lobby, standings, emoji picker, QR invites, six languages and an account chip.
• A real-time Arena server. It runs the rooms and keeps seats across dropped connections.
• Signed identity. The host product says who the person is.
• A signed launch-token tie-in. The host product also says which Event or Space a room belongs to.

A new app reuses the rooms, lobby, standings and sign-in instead of rebuilding them. Apps stay small: the game or trip logic, plus a few lines that plug into the SDK.

The limits matter. The SDK is used by my own apps today. I do not claim outside developers, user counts or speed figures. The real-time side is covered on real-time backend development.

IDUnify: one sign-in

IDUnify is single sign-on for a group of sites. It uses OpenID Connect and Firebase Auth, with an admin console for sites, teams and users, and a shared AI gateway with per-person credits. The demo shows a signed-in account page.

One sign-in means a person has one account across several sites, and the owner has one place to manage them. If you run more than one site or app, this removes duplicate accounts and password resets. For the AI side, see adding AI features. A full write-up is on the IDUnify case study.

What a platform project looks like

Platform work is scoped after the free consult. There is no price list. A typical shape is:

1. A written architecture and the SDK surface.
2. User identity and sign-in.
3. Real-time rooms where they are needed.
4. Integration with your existing product.
5. A tested release, a rollback plan and docs.

You keep your accounts, hosting and domain. No rankings, traffic or downloads are guaranteed.
