Hello, I’m a Full-Stack Developer with 5+ years of experience in PHP, MERN, Flutter, and Android/iOS development, and I’ve built CRM, call-management, and real-time dashboard systems similar to what you described. Your calling-centric CRM with auto-dialer, lead workflows, and web + Android apps is well within my expertise. Proposed Stack Frontend Web: React Mobile App: Flutter (single codebase) or Native Android Backend: Node.js (or Laravel) DB: PostgreSQL / MySQL Telephony: Twilio or Plivo Real-time: WebSockets Payments: Stripe Approach: Build scalable CRM with lead import, segmentation, assignment, and role-based access Integrate predictive/preview auto-dialer with real-time status sync Implement dashboards, reports, exports, and workflow automation Social & lead-gen API integrations Subscription & billing module Timeline: ~8–10 weeks for MVP (phased delivery) You’ll receive source code, API docs, admin/agent guides, and one-month support. I focus on clean architecture, performance, and maintainability. Happy to discuss details and finalize milestones. Best, Bhargav

Your auto-dialer will fail under load if you don't implement a queue system that throttles Twilio API calls and handles carrier rate limits. Most CRM builds I've audited crash at 15-20 concurrent calls because developers skip the orchestration layer between the dialer and telephony provider. Before architecting the solution, I need clarity on two things: What's your expected concurrent agent count at peak hours - 10 or 100? And are you planning multi-tenant architecture where each client gets isolated data, or is this a single-org deployment? The database schema and caching strategy changes completely based on your answer. Here's the architectural approach: - NODE.JS + POSTGRESQL: Build an event-driven backend using Bull queues for call orchestration, Redis for session management, and connection pooling to handle 500+ queries per second without blocking. - TWILIO INTEGRATION: Implement webhook handlers with idempotency keys, automatic retry logic for failed calls, and real-time status updates via WebSockets so agents see disposition changes instantly across web and Android. - REACT + REACT NATIVE: Share 70% of business logic through a monorepo structure, use TypeScript for type safety, and implement optimistic UI updates so lead screens load in under 500ms even on 3G connections. - API DESIGN: Build a GraphQL API with field-level permissions and DataLoader batching to prevent N+1 queries when agents pull lead lists with 1000+ contacts. - STRIPE BILLING: Set up subscription webhooks, handle payment failures gracefully, and implement seat-based licensing with automatic provisioning/deprovisioning tied to your user roles. I've built 4 similar telephony-integrated CRMs that scaled from 20 to 300+ concurrent agents without performance degradation. I don't take on projects where call quality and uptime aren't contractually guaranteed. Let's schedule a 20-minute technical call to walk through your carrier integration requirements and discuss failover strategies before you commit to a build.

Hi, This is exactly the kind of calling CRM I can build, especially with auto-dialing, real-time syncing, and a shared backend for web and Android. Here’s how I’ll handle it: • Scalable Node.js + PostgreSQL backend with clean lead management, segmentation, and reassignment • Twilio or Plivo auto-dialer integration with preview/predictive modes and disposition capture • Fast React web app with real-time call status and smooth agent workflow • Companion Android app connected to the same backend with live sync • Role-based access for admins, managers, and agents • Live dashboards, reporting, and lead source integrations • Automation workflows (missed call triggers, follow-ups, status-based actions) • Subscription and billing system for seat-based plans I focus on building CRMs that are fast, reliable, and optimized for high-volume calling teams, with clean architecture and long-term scalability. Let’s connect on chat. I can begin with the dialer integration and core CRM architecture right away.

@chiragardeshna

Hi there, I am a strong fit for this build because I have designed full-stack CRM systems with integrated telephony and real-time agent workflows. I have implemented lead management, role-based access, auto-dialer flows using Twilio or Plivo, real-time call syncing, analytics dashboards, and Stripe-based subscription modules across web and Android. I work with React on the web, native or Kotlin-based Android apps sharing a Node.js and PostgreSQL backend, using REST APIs, WebSockets for live updates, and structured CI/CD pipelines. I reduce risk by defining call flow architecture and data models upfront, load-testing dialer throughput, isolating telephony services for scale, and documenting APIs and workflows clearly before handover. I am ready to review detailed requirements and start with a phased execution plan immediately. Regards Chirag

@RajAbhisek

Hi, We'll build your full calling-centric CRM as a React web app and React Native Android app sharing a single Node.js/PostgreSQL backend, with Twilio powering the predictive auto-dialer at 30+ calls/minute. Redis handles real-time call status sync across both platforms, and a GraphQL API ties everything together cleanly. Deliverables include the web and Android apps, complete API documentation, an admin guide, an agent quick-start manual, and 30 days of post-launch bug-fix support. SSO, lead integrations, workflow automation, and Stripe billing are all in scope. Ready to lock in a scoping call and firm up the start date. Regards, Raj
