Development of a mobile application for iOS and Android using a ready-made REST API

Budget: 27000 UAH Deadline: 60 days

Good day!

I am interested in your mobile logistics service project. I have experience in developing cross-platform applications for iOS and Android, integrating REST APIs, JWT access/refresh tokens, authorization via Google and Apple, push notifications, payments, working with maps, and file uploads.

I develop on Flutter. The description mentions a React stack. Please clarify whether you mean React Native specifically, or if you are open to considering implementation on Flutter?

I preliminarily estimate the development at 650–850 working hours, depending on the number of screens, design complexity, maps, payment scenarios, and publication requirements. The estimated timeframe is 3–6 months.

My rate is $8 per hour. I can provide a more accurate estimate after reviewing the Postman Collection and agreeing on the mockups.

You need a mobile application for iOS and Android using React Native that works with the existing REST API of a logistics service. I will take on the development. I will integrate authorization with access and refresh tokens, session storage, login via Google and Apple, and manage profiles, addresses, and notifications. I will implement the creation and tracking of parcels, requests for redemption, photo uploads, balance and transaction viewing, bill payments through WayForPay, and delivery routes on the map. I will set up API error handling according to your Postman Collection. I will prepare builds for publication in the App Store and Google Play. I work with JavaScript and TypeScript, and I will align the screens according to the mockups. Write to discuss timelines and start working.

I offer my services for the development of a mobile application on iOS and Android that will use a ready-made REST API. I have experience with Flutter, which allows creating cross-platform solutions and adapting them to the project's needs. I work at a rate of $15/hour.

I am ready to implement the project considering all technical requirements.

Since your API is already fully documented through Postman, I will focus on the quick integration of each screen using React Native and RTK Query for automatic caching of responses and real-time synchronization of package statuses. I will implement a single request interceptor that will automatically refresh the access token through the refresh mechanism on every 401 status, which will help avoid random user logouts from the system.
I have already implemented a logistics application with map integration, payments, and bonuses, so I have a good understanding of the nuances of working with large volumes of transactions and messages.
I can start working as soon as I finish the discussion.

The stack indicated as React, please clarify: React Native or separate native applications?

I looked at the Postman collection: access/refresh tokens, Google/Apple Sign-In, shipments and redemptions, payment through WayForPay, delivery stage map, customs calculator, push notifications. I will integrate screens with the API, handle token and error processing, and prepare builds for the App Store and Google Play.

Deadline: 6-7 weeks, approximately 250-300 hours, hourly rate. Track.

Good day, Dmitry!

I have experience in mobile application development, particularly in integrating with REST APIs. I am ready to create a logistics application for iOS and Android, using your existing backend.

I understand that important aspects include user authorization, package management, and payment system integration. Your project involves implementing functionality that meets modern user requirements.

To propose a specific plan, I need to review the API documentation and clarify if there are specific design requirements. After that, I can prepare a detailed work plan.

The estimated cost of my services is from $30 per hour, and the development timeline will depend on the scope of work, but it usually takes 2-3 months for a full launch.

My profile contains examples of successful projects that may be useful for assessing my expertise.

I suggest discussing the project details in private messages to determine the next steps and agree on all nuances. Expand

Hello, Dmytro! I will implement your application in React Native (one code for iOS/Android). When integrating the ready API, it is important to immediately set up offline mode for maps and tracking so that saved data does not disappear during internet outages.

Which maps does the backend use for geocoordinates — Google or Leaflet?

I will prepare the screen layout and authorization logic. $25/hour, ~280 hours (1.5-2 months).
