"Job Title: Mobile App Developer (Android & iOS) – Webview / SSO Integration

About WISPGate:
WISPGate is a SaaS platform providing advanced Billing, CRM, and Network Management solutions for ISPs (Internet Service Providers). Our system already includes web-based portals for ISP owners and their customers, accessible through a centralized SSO gateway: https://sso.wispgate.io.
We are now looking to extend these interfaces into a universal mobile app for both Android and iOS platforms.

Job Description:
We are seeking a skilled Mobile App Developer (individual or small team) to build a cross-platform mobile application that securely embeds our web interfaces using the existing SSO system.
The app will function as a webview-based container (or hybrid wrapper) that provides seamless access to the WISPGate ecosystem for both:
• ISP Owners: Using their Admin Dashboard via SSO.
• End Customers: Accessing their Customer Portal (CP) via SSO.

Responsibilities:
• Develop and deliver Android and iOS apps that load WISPGate’s web interfaces within a secure and optimized webview.
• Integrate the SSO login flow through https://sso.wispgate.io.
• Ensure proper session persistence, cookies, and login state management across app launches.
• Implement basic app navigation controls (loading screen, back/refresh, etc.).
• Handle mobile permissions and push notifications (via Firebase or OneSignal).
• Ensure smooth performance, responsive scaling, and clean UX while loading dynamic web content.
• Provide source code via GitHub (or GitLab) repository for version control and testing.
• Include the Splash Screen Video before/while the app is loading

Requirements:
• Proven experience developing Webview-based hybrid apps (React Native, Flutter, Ionic, or native Android/iOS).
• Strong understanding of SSO / OAuth2-based authentication flows.
• Experience with responsive webview rendering and mobile optimizations.
• Familiarity with Firebase push notifications or similar frameworks (optional but preferred).
• Ability to deliver both Android and iOS builds ready for upload to the Play Store and App Store.
• Excellent communication skills and ability to work independently.

Project Details:
• Scope: Single mobile app (Android & iOS) embedding SSO-based web interfaces.
• SSO URL: [login to view URL]
• App Type: Hybrid / Webview container
• Delivery: Working app build + code in Git repository
• Store Publishing: Handled by the WISPGate team (you’ll deliver ready-to-upload build files).
• Access: Developer will receive Git repo access (for app wrapper only — not full backend codebase).

Deliverables:
• Android (.apk / .aab) and iOS (.ipa) builds
• Clean, maintainable source code (via Git repo)
• Documentation for build and configuration steps
• Basic push notification setup

How to Apply:
Please include:
• A short intro about your experience with hybrid app development or webview-based apps.
• Links to previous apps or GitHub projects.
• Estimated timeline and budget for this project." (client-provided description)
