Full-Stack App & CRM Integrations

@corpmember29

Hello, I have carefully reviewed your requirements and understand that you need a hybrid full-stack app with a single codebase for iOS, Android, and web, integrated deeply with Salesforce Service Cloud and Zendesk, supporting thousands of tickets, real-time sync, and polished UX. I have 10+ years of experience in full-stack and mobile development, including hybrid apps, CRM integrations, and scalable API design. My proposed approach: Database: PostgreSQL for relational consistency with high concurrency, optional Redis caching for speed Backend: Node.js/Express with REST or GraphQL, role-based auth, logging, test coverage Front-end: React Native + Expo (web support via React Native Web), fully responsive and maintainable CRM Integrations: Salesforce and Zendesk via APIs and webhooks, supporting two-way sync Deployment: TestFlight, Google Play internal track, and production web URL; environment configs and migration scripts included Deliverables: Complete, documented source code in private Git repo Working builds on iOS, Android, and web Migration scripts and environment setup instructions Short recorded hand-off session covering deployment, integration keys, and workflow I will provide 2 years of free ongoing support, work with agile methodology, and assist from setup to publishing. Comparable hybrid apps and CRM integrations are available in my portfolio upon request. I eagerly await your positive response. Thanks.

Hi, This is Elias from Miami. I’ve checked the scope and I understand you need an end-to-end hybrid app (web + iOS + Android from one codebase) that manages support tickets and stays in sync with Salesforce Service Cloud + Zendesk (create, status, two-way comments, webhook updates). You also want a solid data model, secure API layer, RBAC/logging/tests, fast response times on 10k tickets, and clean handoff docs + recorded walkthrough. For stack, I’d lead with React Native + Expo (web + mobile) and a Node/NestJS API with Postgres. Postgres is a good fit here because tickets/comments/events are relational and you’ll want indexing + query performance at scale. Sync would be event-driven: webhooks from SF/Zendesk → queue/worker → local DB updates → push updates to clients. That’s the cleanest way to hit “instant” sync without polling. Additionally, a few questions: Q1: Do you want this to be the source of truth, or is Salesforce/Zendesk the source of truth with your DB as a fast cache + audit log? Q2: How should conflicts be handled if the same ticket is edited in two places (last-write-wins, field-level merge, or lock on edit)? Q3: Will users connect their own SF/Zendesk accounts (multi-tenant OAuth), or is this for one org with shared admin-managed credentials? If you answer those, I can outline a milestone plan (schema/API → connectors + webhook sync → hybrid UI → performance + QA → TestFlight/Play + deploy) and share comparable integration work in chat. Regards.

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Hybrid app with real time CRM sync across web, iOS, and Android ))⚜⭐⭐⭐⭐⚜ What stands out here is that you are not looking for disconnected pieces. You want one clean system that starts with the data model and ends with a polished hybrid experience that behaves consistently on mobile and web while staying tightly synced with Salesforce and Zendesk. You are essentially building a unified support platform where tickets, comments, and status updates move instantly between your app and external CRMs, supported by a scalable backend and a single shared codebase for all platforms. I have delivered full stack applications where database design, API performance, and third party CRM integrations must stay reliable under load. I pay close attention to webhook handling, permission models, and keeping response times predictable as data grows. Three core elements I would focus on: • Scalable ticket data model with fast read and write performance • Hybrid front end that packages cleanly for web, iOS, and Android • Two way CRM synchronization with webhook driven updates If this sounds aligned, I would be glad to discuss stack choice, integration approach, and a realistic delivery timeline before moving forward. Warm Regards, Farhin B.

@ParasTech7

Hi, I have experince of 21 years, we can use React and web app view to have single code base to run both on mobile and web, if you want more native like experince the app can be made on React Native which will run for both ios and android. We can use SQL for database, build proper schema, use worker threads for concurrency in node js or better choose java multithreading concurrecy. The app can be build with REST API with MVC architecutre to maintain industry level efficiency. We will follow frontend first approach keep building UI and integrate the APIs as required. We can then shift to salesforce and zendesk integration, i have previous experince of integrating these platforms,tickets can be created and it can be made interactive via webhooks. We can also provide API documentation to you, all the source code, env, database schema and required files.

I also designed a robust database schema that efficiently handled thousands of concurrent users, ensuring smooth operations. ✅My Plan: - Design a scalable, secure database schema (I'll recommend the best option). - Build a REST or GraphQL API layer with stringent authentication and role management. - Develop a hybrid app using React Native with Expo for consistency across platforms. - Ensure deep integration with Salesforce and Zendesk for real-time ticket management. - Provide thorough documentation and onboarding support for your team. I'd love to know what specific features you're envisioning for the Salesforce integration and if you have preferred testing frameworks. Best regards, Hongqiang Chen

@emilesd617

Hi, I am a full-stack developer with 8 years of solid experience in application development. I am familiar with React Native, Ionic/Capacitor, HTML5, API development, database design (SQL and NoSQL), authentication and role-based access control, and building scalable backend services for high-concurrency systems. For this project, I would lead with a single hybrid codebase (React Native + Expo or Ionic + Capacitor) to ensure consistent UX across web, iOS, and Android. I can design a ticket-focused data model optimized for fast reads and writes, build a secure REST or GraphQL API, and implement two-way synchronization with Salesforce Service Cloud and Zendesk using webhooks and background jobs so ticket updates stay in sync in near real time. The solution will be structured to allow additional CRM integrations later without refactoring core logic. I'm an individual freelancer and can work in any time zone you want. Please contact me with the best time for you to have a quick chat. Looking forward to discussing more details. Thanks. Emile.
