I’m building a two-part solution and need an experienced app developer who can take both pieces from concept to store-ready release. Part 1 is a lead-collection service that must run natively on both iOS and Android. The app will let sales reps submit a simple, secure form, watch the system auto-assign each lead based on predefined rules, and follow progress in a real-time tracking dashboard. Clean CRM integration is essential so all data flows straight into the central database without manual exports. Part 2 is a customer-facing CRM services app, offered through a responsive web interface and mirrored in a companion mobile app. Subscribers should be able to log in, view the leads pushed from Part 1, manage pipelines, and purchase additional CRM features from within the product. I expect a modern cross-platform codebase, clear API design, and deployment support all the way through App Store / Google Play submission and web hosting. If you’re confident with tools like Flutter or React Native for the mobile side and a scalable backend stack (Node, Django, Firebase, or similar), let’s talk about timelines and milestone delivery.

Hi, This is Elias from Miami. I checked your project description and understand you need a two-part platform: first, a cross-platform lead collection app for sales reps with secure form submission, rule-based lead assignment, CRM sync, and real-time tracking; second, a customer-facing CRM product available on web and mobile where subscribers can manage leads, pipelines, and purchase extra CRM features. The goal is to build both sides as one clean ecosystem with shared backend logic, smooth data flow, and store-ready deployment. My approach would be to design the backend and API layer first so both apps share the same source of truth, then build the rep app and customer CRM in parallel with a modular architecture that supports real-time updates, billing, and future feature expansion. I have a few questions to get a better understanding: Q1 – Do you already have the lead-assignment rules and CRM data structure defined, or should the first phase include shaping that backend logic together? Q2 – For the customer-facing CRM, do you want subscription billing and in-app feature purchases included in Phase 1, or should that come after the core lead and pipeline workflows? Q3 – Would you prefer one cross-platform mobile codebase for both the rep app and customer app, or do you see them as two separate products sharing the same backend? Looking forward to hearing from you.

This two-part solution clearly needs seamless data flow and smooth user experience. For Part 1, I suggest building the mobile app in Flutter to quickly deliver native performance on both iOS and Android. The lead form and auto-assignment logic can run in real-time with cloud triggers, ensuring reps see immediate updates on their dashboard. I’ve built similar lead tracking apps where real-time syncing cut the manual update work by 90%. For Part 2, a responsive React web app paired with the same Flutter mobile codebase will keep features consistent across platforms. To avoid data delays, I’d design a unified API that handles both lead visibility and in-app purchases securely. Have you defined the user roles and permissions yet, especially for purchasing additional features? Also, what CRM system will this integrate with—should I plan custom connectors or use existing APIs? I focus on clean API design and smooth deployment, so I’ll help guide you through App Store and Google Play submissions and set up scalable hosting. Let’s align on milestones and timelines so I can start delivering quickly.

Our frontend and backend leads are well-versed with Architect design, ensuring your system can scale efficiently on both iOS and Android. The real-time tracking and CRM integration are exactly where we shine.

It resulted in a 30% increase in their operational efficiency, with smooth App Store and Google Play submissions. I'll be your direct technical point of contact, and we'll set up a staging environment for iterative testing and feedback. This ensures that any CRM integration or lead assignment rules are spot on before going live. What's your long-term vision for CRM feature expansion within the product?
