OnGuardian

A unified SaaS and mobile platform that lets one team generate multiple organization-specific apps from a single Flutter and Node.js foundation.

Role

Architecture, SaaS administration, and cross-platform app delivery

Delivery

Single codebase system for multi-organization app generation

Platforms

Web admin, iOS, Android

Tech stack

Node.js, React, Firebase, Flutter

Overview

What the project needed to accomplish.

OnGuardian combines a SaaS control layer with a mobile application framework to manage and distribute customized content across multiple organization-specific apps. The published case study describes it as a scalable platform for tailoring app experiences without rebuilding the full stack for every organization.

Challenge

The delivery problem was multi-tenant in practice: support different organizations, app properties, and content rules while keeping development efficient and data safely isolated between deployments.

Solution

The implementation uses a single Node.js backend codebase, a React admin portal, and one Flutter codebase to drive multiple mobile applications. Dedicated Firebase databases per app keep data segmented, while admin controls, multilingual content setup, and notifications support organization-specific experiences.
