Full-Stack App & CRM Integrations
Budget: $250 – $750 USD
I need a seasoned full-stack developer to take an idea all the way from data model to polished user experience. The solution will present the same interface whether it is opened in a browser or installed on a phone, so a single hybrid code-base is essential. The mobile build must compile cleanly for both iOS and Android, while the web version should feel like a first-class responsive application on desktop screens.
Core scope
• Design and implement a scalable, secure database schema (SQL or NoSQL—convince me which fits best) that can comfortably support thousands of concurrent support tickets.
• Build a robust back-end API layer (REST or GraphQL) with authentication, role-based permissions, logging, and sensible test coverage.
• Develop the front-end as a hybrid app that packages for iOS, Android, and the web without code divergence. Think React Native + Expo, Ionic + Capacitor, or Flutter Web, but I’m open to other proven stacks.
• Integrate deeply with Salesforce Service Cloud and Zendesk. Ticket creation, status syncing, two-way comments, and webhook-driven updates all need to run smoothly. If the foundations allow room for a future Helpdesk.com connector that would be ideal.
• Provide concise documentation and an onboarding walkthrough so my internal team can deploy new environments and iterate on the UI.
Acceptance criteria
1. A working build published to TestFlight, Google Play internal track, and a live web URL.
2. CRUD operations on tickets reflected instantly across the local database, Salesforce, and Zendesk.
3. All source code, migration scripts, and environment files committed to a private Git repo with clear README instructions.
4. Response times under one second for common API calls in a staging environment loaded with 10,000 sample tickets.
5. A short hand-off session (recorded) demonstrating deployment, integration keys, and versioning workflow.
If this end-to-end challenge excites you, please tell me which stack you’d lead with and show any comparable hybrid apps or CRM integrations you have shipped.
