Hi there, I reviewed your PWA deployment project and this is exactly the kind of work we handle well. I noticed you need a backend developer to get your customer-facing mobile web app live — we've done plenty of similar launches with Node.js and RESTful APIs. I have a couple of quick questions about your infrastructure preferences and timeline that would help me scope this properly. Happy to jump on a call if that works better. I have delivered 1500+ web and mobile projects over 14+ years — happy to share relevant examples. Thanks, Hasan

Hi there, As you already have the complete React PWA prototype, API documentation, and populated MySQL database ready, I can help you build the 7 REST APIs, connect the existing React frontend with live data, handle authentication/file upload flows, and deploy the complete PWA properly on your live domain with CORS and DNS configuration. I have spent the decade working on React + API based platforms, so I know the small issues that usually come during wiring existing UIs with real APIs, especially around auth flow, CORS, session handling, and deployment stability. Once you share the repository and API specification, I will first review the existing React screens, database structure, and the exact frontend integration points you already mentioned, then start building the 7 APIs step by step while testing every flow directly with the live UI instead of developing things separately. After the APIs are connected, I will handle the PWA deployment on your domain, configure CORS/DNS properly, and make sure the package flow, invoices, login system, and pre-alert upload functionality work smoothly end-to-end on both mobile and desktop. I would request to connect once so we can quickly go through the current setup, hosting preference, and deployment flow. Thanks, Rahul A.

You need a backend API to bring your React PWA live for a package-forwarding business — 7 REST API endpoints exactly as specified (auth login/logout, get user, list packages, package detail, list invoices, submit pre-alert with file upload), wired to your existing MySQL database, with CORS configured and deployed to production. At Harmis Technology, we have built SaaS platforms (BestMART B2B marketplace, LostReturns, SmartQr) with robust Laravel/PHP REST APIs, MySQL databases, and complete API documentation — this is the exact type of backend work we specialize in. We will deliver all 7 endpoints, wire them to the React PWA prototype at the 3 specified locations, and deploy to your server within 10 days. Can you share the API specification document to confirm full scope?

@sabaehsan

Greetings, I see you're looking for a backend developer to help launch your PWA for a package-forwarding business in Trinidad. It sounds like you have a solid foundation with the frontend and the API specification already in place. My approach would involve building the seven REST API endpoints as outlined, ensuring they connect seamlessly with the existing React prototype. I’m experienced in developing APIs, and I can choose the right stack for your needs, whether it's PHP, Node.js, or Python. Once the endpoints are set up, I'll wire them to your prototype and deploy the PWA on a suitable static host like Vercel or Netlify, handling the necessary CORS and DNS configurations. You can expect clean, documented code throughout the process, and I’ll keep everything organized in a Git repository. Best regards, Saba Ehsan

@vladang

Your PWA is solid on the frontend; the key risk is ensuring the backend API strictly matches your spec so production behavior stays consistent. I’ll wire your React screens to a reliable backend so users can log in, track packages, and manage invoices smoothly. I’ll build the REST API in Node.js (Express) exactly per spec, integrating with your MySQL database. Auth, packages, invoices, and file upload endpoints will include validation, error handling, and CORS for your domain. I’ll connect the PWA to API at the three marked integration points ensuring clean data flow. Deployment via Vercel/Cloudflare Pages with DNS pointing to app.swiftboxtt.com. Everything will be version-controlled with clear setup instructions for easy deployment or extension. Q1: Do you require token refresh or simple session auth only? Q2: Should file uploads be stored locally or external storage? Q3: Any strict performance or rate limiting expectations for API?

@Herculesz

Hello, the project to bring a fully designed React PWA live with a backend API and deployment is straightforward yet requires precise integration and deployment discipline. The real engineering risk lies in orchestrating seamless API wiring, authentication flows, and reliable file upload handling under production constraints. I usually structure backend systems with clear separation of authentication, data retrieval, and transactional endpoints to ensure maintainability and scalability. I've built several production systems where I integrated frontend prototypes with backend APIs, ensuring clean, documented code and smooth deployments. In particular, the Custom Feature Development & Integration project aligns well, where I performed codebase reviews, implemented backend features, and delivered deployment-ready code. Additionally, the Squarespace Checkout Streamlining project highlights my ability to handle user flows and backend logic tightly coupled with frontend interactions. I approach API design by separating concerns between authentication, data access, and file handling, balancing simplicity and robustness. This includes careful error handling and ensuring CORS and DNS configurations support smooth frontend-backend communication. I can start by outlining the API endpoint implementations, mapping the React prototype wiring points, and sketching the deployment and CORS configuration strategy for your static host. Thanks, Hercules
