I’m building an end-to-end system for an air-and-sea freight company and need a developer who can deliver both a web application and companion iOS/Android apps. The platform has two tightly linked modules: 1. Warehouse Operations The back-office side must handle receiving and dispatching cargo with solid inventory tracking, smooth order-fulfillment workflows, and clear reporting/analytics so staff always see stock positions, shipment status, and performance KPIs in real time. 2. Customer Portal Shippers will log in to book or follow their consignments, track progress mile-by-mile, download or settle invoices, and receive automatic status notifications (email, push, or SMS). QuickBooks Online integration is non-negotiable: invoices raised in the portal have to sync bi-directionally so finance stays in step without manual re-entry. Core expectations • Responsive web front end plus native-feel mobile apps using the same API stack • Secure multi-tenant architecture (each client views only their own data) • Role-based access inside the warehouse module • Clean, modern UI/UX for staff and customers alike • Documentation and hand-off so my internal team can maintain basic configs Acceptance criteria • Demo environment showing warehouse intake → dispatch flow with sample data • Live QuickBooks sync: create invoice in portal, see it appear in QBO, mark paid in QBO, see status update back in portal • Mobile apps published to TestFlight / Google Play Internal Testing with push notifications firing on status changes • Source code, DB schema, and deployment scripts provided in Git If you have shipped similar logistics or inventory systems and can point me to them, let’s talk—ready to start as soon as the right fit is found.

Hi, This is Elias from Miami. I checked your project description and understand you need a full logistics platform for an air-and-sea freight company, with a warehouse operations system for intake, dispatch, inventory, and reporting, plus a customer portal and mobile apps for booking, tracking, invoices, and notifications. I would approach this by designing a shared API-first backend first, then building the warehouse module, customer-facing portal, and companion mobile apps around a secure multi-tenant structure with QuickBooks sync handled as a core workflow, not an afterthought. I’ve worked on multi-user platforms involving logistics-style flows, inventory visibility, invoicing, notifications, and mobile/web systems sharing the same backend. I’d be happy to go through the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – Do you want the mobile apps built in Flutter/React Native for a shared codebase, or do you prefer native apps while keeping one backend API? Q2 – For warehouse operations, do you already have a defined workflow for intake, storage, picking, dispatch, and status transitions, or should I help formalize that as part of the architecture? Q3 – Beyond QuickBooks, are there any other shipping, customs, barcode, or notification integrations that the first release needs to support? Looking forward to hearing from you.

Your project clearly needs tight integration between warehouse operations and the customer side, with real-time updates and solid QuickBooks syncing. I built a similar inventory and shipping platform for a logistics client last year. We linked order fulfillment workflows with a customer portal, enabling real-time shipment tracking and invoice sync through QuickBooks. The key was designing role-based access to keep data secure and separate while using a unified API for both web and mobile apps. Do you have a preferred tech stack or hosting environment in mind? Also, for notifications, will you need support for multiple languages or time zones? These can affect the messaging setup. I can deliver your requirements on a demo environment with sample data flows, a tested QuickBooks bi-directional sync, and native-feel mobile apps with push notifications. I’ll also provide full documentation and deployment scripts so your team can pick up from there. Ready to start building your platform and get a working demo in place quickly.

Hi there, Cargo platform with tight QuickBooks sync and a shared API for web and mobile, scope we have shipped. Stack: NestJS + Postgres + Redis backend, React web, Flutter for iOS and Android on one codebase. QuickBooks Online sync is the usual burn. OAuth 2.0 + QBO webhooks, a sync log with idempotency keys, retry queue for rate limits. Portal invoices post to QBO; QBO payments flip portal status. No duplicates on replay. Multi-tenancy via Postgres row-level security per tenant_id (not schema-per-tenant); one migration covers all. Warehouse dashboards use a tenant-scoped WebSocket for real-time stock and shipment updates. Tracking: FCM push for status events, carrier pulls for vessel/flight location (Flightradar24, MarineTraffic), SMS via Twilio. Questions: 1) Preferred carrier data source? 2) QuickBooks tenant connected? 3) User counts at launch? Happy to share a milestone plan after an intro call. Best regards, Faizan
