I also have strong expertise in building scalable customer portals, real-time chat systems, and CRM-integrated ticketing solutions. I have reviewed your requirements and understand the need for a secure subscriber management app with OTP login, usage tracking, invoicing, renewals, and seamless support integration. For the chat module, I would implement a real-time solution using Firebase/Socket-based architecture to ensure sub-2-second latency on 4G networks. For the ticketing system, I would design an API-driven workflow synced with your CRM, ensuring instant ticket creation, status updates, and push notifications within one minute. I can deliver a production-ready, Play Store compliant Android app with clean architecture, proper documentation, and smooth handover. Estimated timeline: 10–14 days depending on API readiness.

@arehman171

Hi there, With 4 years of experience in Android development, backend integration (Python/Node.js/Spring Boot), and real-time communication systems, I can build your ISP customer app with OTP authentication, account management, CRM-integrated support, and a modern Android experience. For chat, I would use Firebase or WebSocket-based real-time messaging integrated with your CRM, while the ticket module would create and sync tickets directly through your API with push notifications for status updates. I’ll deliver a clean Kotlin-based application, complete API integration documentation, production-ready APK/AAB, and a maintainable architecture designed for future expansion. Could you share which CRM platform you are currently using and whether the live chat API is already available or needs to be integrated through the CRM?

@RajAbhisek

Read the brief — Kotlin Android app for ISP subscribers: phone + OTP login (Firebase Auth), plan/usage/invoice screens, in-app live chat + ticketing, both synced to your existing CRM. Acceptance targets: 95% OTP success, <2s chat latency, ticket sync <1 min, clean Play Pre-Launch report. Shipped subscriber-side mobile apps with CRM-backed chat + ticket flows before — same architecture. Approach: Firestore for chat messaging (keeps latency well under 2s), bidirectional webhook with your CRM for ticket status sync, FCM for push, Firebase OTP for auth. Crashlytics + Performance Monitoring for the Play Pre-Launch metrics. Deliverables: full Android Studio project, signed APK + AAB, Postman collection for the CRM endpoints, hand-off walkthrough video for your in-house team. On @krishbusiness005's question — CRM webhook latency and OTP success are the two acceptance gates with the most failure risk; worth confirming your CRM's webhook SLA upfront. Ping me to discuss.

@Mats100

Hello, I can build your ISP customer self-service Android app with OTP login, plan management, real-time usage tracking, invoice history, renewals/upgrades, live chat, and CRM-integrated ticketing. For the chat module, I would use WebSocket-based real-time messaging to keep response times under 2 seconds on a typical 4G connection. The ticketing system will create reference numbers instantly, sync with your CRM through the provided APIs, and send push notifications whenever ticket status changes. The app will be developed in Kotlin following Play Store best practices, with Firebase OTP authentication, push notifications, crash analytics, and a clean, modern UI. You'll receive the complete Android Studio project, signed APK/AAB, API integration documentation, Postman collection, and a hand-off session for your team. Based on the scope, I estimate 3–5 weeks for development, testing, CRM integration, and Play Store readiness. I can start after reviewing the API documentation and CRM endpoints.

@dushyant317

Hello, I can develop a production-ready Android ISP customer app with OTP login, plan & usage dashboard, invoice history, renewals/upgrades, live chat integration, and ticketing system synced with your existing CRM via APIs, built in Kotlin with clean architecture and Play Store–compliant standards.

@Anika1802

Hey! As an experienced full-stack developer with a strong background in API integration, Java, and mobile app development, I am confident that I am the right fit for your ISP Customer Android App project. With over 5 years of working with various businesses globally, I have developed an intuition to understand their needs and deliver their vision as a functional, robust product, just as I would do for you. What sets me apart is not only my technical skills but also my ability to think beyond the code. For your chat and ticket modules, I foresee integrating your existing CRM seamlessly with the app while ensuring quick syncing without any data loss. I will ensure that your app satisfies all acceptance criteria, leveraging Kotlin/Java for clean codes, Firebase for OTP authentication and push notifications alongside Google's recommended Play Store Guidelines. Moreover, my broad experience in building and scaling SaaS platforms will come in handy as it demands integration of various systems with efficient execution - a challenge that excites me. While delivering a high-performance product is essential, maintaining it post-handoff is equally important. That's why I'll make sure to provide detailed API integration documentation and offer a brief hand-off session or video walk-through for your team's ease post-project.

@ApieTech

We build Android apps at Apie Technologies using Kotlin + Firebase — OTP authentication, push notifications, API integrations, and Play Store deployment are standard deliverables for us. For the chat and ticket modules specifically: live chat can run on Firebase Realtime Database (or a WebSocket if your CRM prefers that) — syncing under 2s on 4G is straightforward with this architecture. For ticketing, we'd POST ticket data to your CRM API on creation, store locally with Room DB for offline resilience, and push FCM notifications on every status change. Both channels will be wired against the API docs and test credentials you provide. OTP auth via Firebase Phone Authentication handles the 95% first-attempt success requirement reliably. 30-day timeline: Week 1 — auth + account screens. Week 2 — data usage/invoice/upgrade flows. Week 3 — chat and ticketing with CRM integration. Week 4 — testing, crash analytics (Firebase Crashlytics), signed APK/AAB, and handoff docs. What CRM system are you integrated with — do you have a REST API spec we can review before we start?

@serviceaxisgroup

Hi, I can help with an Android subscriber app where customers can view plan details and real-time data, manage invoices, renew or upgrade, and get full in-app live chat and ticketing synced to your CRM. I’ll start by confirming your CRM/chat APIs and designing the Kotlin architecture, screens, and Firebase OTP flow end-to-end. To reduce risk, I’ll build in small milestones with early integration mocks, performance checks for chat, and a sync test plan against your test credentials. Which CRM endpoints and authentication method will we use for chat and tickets? Do you prefer Java or Kotlin for the production codebase? If you share the API docs, we can align on timeline and begin.
