App for Android and iOS

@leadconcept

Hello, We can build your two-sided marketplace with a production-ready cross-platform mobile app for iOS and Android, plus a scalable backend designed for future web expansion. The app will support Client and Service Provider roles, OTP/password-less authentication, multi-step request forms, offer tracking, lightweight messaging, and automatic PDF summaries. We will provide a REST/GraphQL API, a flexible database schema, and a web-based admin panel ready for user and transaction oversight. Questions to clarify: 1. Are there specific tech preferences for the mobile stack (Flutter, React Native, or others)? 2. Should document generation be PDF-only or extendable to other formats? 3. Any preferred cloud or hosting environment for staging and production? Our experienced team has delivered two-sided marketplace apps with OTP flows, modular backend design, and scalable architecture. We will provide clean code, Git versioning, deployment scripts, unit tests on critical flows, and clear documentation so future teams can extend the platform easily. FYI. The bid amount is a placeholder to submit the proposal. Regards Yasir LEADconcept PS: Let me know, if you want to see our team past work to determine our skills/expertise or past customer's references.

Hello, I’ve reviewed your plan for a two-sided marketplace and a solid mobile-first backend. You want a production-ready cross-platform app (iOS/Android) with OTP-based sign-in, a guided client posting flow, provider responses and status updates, in-app messaging, automatic job summaries, and a scalable API + database with an admin panel and future monetisation hooks. I will deliver clean, modular code, clear docs, Git-based versioning, staging/production deployment scripts, and essential tests. My approach is to build a robust React Native frontend paired with a PHP-based API and a relational data model that supports future web front-ends (React/Vue) and Stripe-like payments. The backend will be designed for easy expansion, with GraphQL/REST, role-based access, and event-driven state updates. I’ll set up a testable auth flow (OTP/password-less), a guided client form, and a lightweight message layer, plus auto-generated PDFs for confirmed jobs. The result will be a scalable base you can grow from. What are the top priority features to ship in the first 6 weeks, and do you prefer GraphQL or REST as the main API for the MVP?

@diektech

Hi, this is Elias from Miami. I read your scope and I’m clear on the MVP: a two-sided marketplace mobile app (iOS + Android) with OTP phone auth, client request posting (multi-step), provider offers + status flow, lightweight in-app chat, auto PDF summaries for confirmed jobs/offers, and a clean backend (REST/GraphQL) + admin panel that’s ready for a future web front end and monetization. I’ve built marketplace-style apps and backend systems where the core is a solid data model + state machine (request → offers → acceptance → job status), with clean modular code, tests on critical flows, and deployment-ready environments (staging + prod). I’m also comfortable setting this up with Git discipline (clear commits/issues) and documentation so another team can extend it later. Previous work: multi-role platforms, OTP/auth flows, messaging, admin dashboards, and API-first architectures designed to support mobile now and web later. Q1: For OTP, do you have a provider preference (Twilio / AWS SNS / MessageBird), and which countries need support at launch? Q2: What’s the minimum job lifecycle you want in v1 (e.g., Posted → Offered → Accepted → In Progress → Completed/Cancelled), and do you need dispute/refund states later? Q3: For messaging, should it be real-time (WebSockets) or is near-real-time polling acceptable for MVP? Regards.

@divumanocha

Hello, I’m excited about the opportunity to help you build a strong, scalable foundation for your two-sided marketplace. I have experience developing cross-platform marketplace applications with extensible backend architectures, OTP-based authentication flows, and modular systems designed for long-term growth. For the mobile app, I recommend Flutter or React Native to deliver a single, maintainable codebase for iOS and Android. I’ve implemented secure phone-number registration with OTP (via Firebase Auth or custom SMS gateway), including fully password-less flows and token-based session management. On the backend, I would build a clean REST (or GraphQL) API using Node.js (NestJS) or Laravel, structured with clear service layers and role-based logic (Client / Provider). The database schema will be normalised and designed for future expansion, including monetization (Stripe), subscriptions, and a future React/Vue web frontend. Core features such as guided multi-step request forms, offer/status management, lightweight real-time messaging (WebSockets), and automated PDF job summaries will be implemented with scalability in mind. An admin panel (React or Laravel Nova) will provide oversight of users, requests, and transactions. I’d be glad to discuss your roadmap and define the first production milestone. Best regards,

@SBITServices

Hi, I propose to develop a cross-platform mobile application for iOS and Android that supports Service Providers and Clients. The app will include phone-number registration with OTP verification, guided form for detailed requests, offer and status management, in-app messaging, automatic document generation, REST/GraphQL API, web-based admin panel, and future monetization options. Let's discuss further. Regards, Sai Bhaskar

@vishal1145

Your two-sided marketplace will fail at scale if the database schema treats Service Providers and Clients as separate tables instead of a unified user model with role-based permissions. I've seen three startups rebuild their entire backend six months in because they couldn't handle users switching roles or offering both services and requesting them. Before architecting the solution, I need clarity on two things: What's your expected transaction volume in year one - 100 jobs per month or 10,000? And does your business model require real-time offer notifications, or can Providers check a dashboard every few hours? These answers determine whether we build on Firebase for speed or PostgreSQL for complex queries. Here's the architectural approach: - REACT NATIVE + TYPESCRIPT: Single codebase for iOS and Android with shared business logic, cutting development time by 50% while maintaining native performance for camera uploads and push notifications. - PHP LARAVEL + REST API: Build a stateless API with JWT authentication and rate limiting at 1000 requests per minute, plus queue workers for PDF generation so document creation doesn't block the main thread. - TWILIO VERIFY API: Implement OTP flows with automatic retry logic and fraud detection to prevent SMS bombing attacks that cost you $500 in the first week. - POSTGRESQL + REDIS: Design a normalized schema with proper foreign keys and indexes, then cache frequent queries in Redis to keep response times under 300ms as you scale past 50K users. - STRIPE CONNECT: Pre-wire the payment rails using Stripe's marketplace product so you can take commission without touching funds directly, avoiding PCI compliance headaches. I've built four marketplace platforms that processed $2M+ in transactions within their first year. Two required complete rebuilds because the founding team skipped the schema design phase. Let's schedule a 20-minute technical call to walk through edge cases - what happens when a Provider ghosts a Client mid-job, or when someone disputes a completed request? I don't start coding until we've mapped failure scenarios.
