SaaS Platform Mobile App Development

Mobile App Developer / Team Needed – Existing SaaS Platform (iOS + Android)

We are looking for an experienced mobile app developer or small team to build native-feeling iOS and Android applications for an existing field service management platform.

This is NOT a startup idea from scratch. The backend, APIs, workflows, routing logic, authentication, scheduling systems, and business logic already exist and are actively used.

The goal is to build polished mobile applications that connect into the existing platform architecture.

Project Overview

We already have:

* Existing production web application
* Existing API/backend infrastructure
* Existing authentication/session systems
* Existing scheduling/dispatch systems
* Existing invoice/job/client workflows
* Existing technician workflows
* Existing permissions/role systems
* Existing mobile-oriented PWA
* Existing UI/UX patterns and workflows

The mobile apps should leverage the current backend systems and APIs rather than rebuilding platform logic from scratch.

Primary Goal

Build high-quality iOS and Android mobile applications that:

* Use our existing APIs and backend
* Follow existing workflows and business logic
* Improve the mobile field technician experience
* Support offline-aware workflows where appropriate
* Feel polished and production-ready
* Scale long-term with the platform

Preferred Technical Direction

We are open to:

* React Native
* Capacitor/Ionic
* Flutter
* Other modern cross-platform approaches

Preference will be given to developers who can justify the architecture choice clearly based on:

* maintainability
* scalability
* performance
* offline capability
* long-term support

Current Stack

Current platform stack includes:

* React
* TypeScript
* Vite
* Node.js / Express
* PostgreSQL
* Existing REST APIs
* Existing authentication/session architecture
* Existing PWA implementation

Core Areas of the App

The app will include workflows such as:

* Technician dashboard
* Today's schedule
* Dispatch/job management
* Job details
* Client information
* Notes/photos/attachments
* Time tracking/timesheets
* Invoice/payment visibility
* Maintenance plans
* Push notifications
* Offline-aware functionality
* GPS/location-related workflows
* Role/permission-based access

What We Need From You

We are NOT looking for:

* template installers
* basic UI wrappers
* low-code/no-code agencies
* someone learning mobile development on the job

We ARE looking for:

* strong mobile architecture experience
* experience integrating into existing APIs/platforms
* attention to UX and performance
* clean scalable code
* understanding of production deployment
* App Store + Google Play deployment experience
* strong communication and documentation

Deliverables

Expected deliverables include:

* iOS application
* Android application
* Source code
* Build/deployment documentation
* Store deployment assistance
* Environment configuration documentation
* Recommendations for push notifications/offline strategy
* QA/testing process

Bonus Experience

Bonus if you have experience with:

* Field service software
* Dispatching systems
* Offline-first mobile apps
* Real-time updates
* Maps/GPS integrations
* Push notification systems
* Stripe/payment integrations

Important

This project already has an established architecture and workflow system. We are looking for someone who can build on top of the existing platform intelligently, not reinvent the platform logic itself.
