Developing a food ordering app

Let’s dive deep and review the steps to create a food ordering app:

1. Prepare the project scope statement

While the location, participating restaurants, etc. are the concerns of the business stakeholders, you need a project scope statement for the app development part. As part of the project scope, I recommend you build the following:

A web app;

An Android app;

An iOS app.

The apps should have the features I have described above.

2. Use the Agile methodology

While the above scope is good for the initial launch of your app, you might need to add more features in the future. That calls for iterative development, therefore, use the Agile methodology. To know why Agile SDLC model helps in iterative development, read “What is software development life cycle and what you plan for?”.

3. Organize your development team

Organize a team with the following roles:

Business analysts (BAs);

UI/UX designers;

Web developers with Node.js skill;

Android developers with experience in Kotlin;

iOS developers with expertise in Swift;


A project manager (PM).

You should use the “Scrum” technique to manage this Agile project. The PM should perform the role of a “Scrum master”, and he/she should form small cross-functional teams. These are called “Scrum teams”. Read more about Scrum in “How to build a Scrum development team?”.

4. Prepare for future internationalization

You might launch your app in one geography now. However, it pays to design and develop in a manner that makes future launches in other geographies easy. You should follow “app internationalization” guidelines, for e.g.:

Code in a manner that the programs can pick content from different files based on geographic region.

Keep content separate from the code.

Design UI in a way that it can easily support the launch in other geographies.

Read more in “The ultimate guide to mobile app internationalization”.

5. Use a modern PM tool

A scrum team works as follows:

A “Product owner” provides the features in a document called “Product Backlog”.

The team estimates the features, prioritizes them and plans “Sprints”, i.e., iterations.

Project status tracking happens via a “Daily stand-up meeting”.

Sprint approval happens in a meeting called “Sprint review meeting”, provided features are working.

There is a lessons-learned exercise called “Sprint retrospective meeting”.

Careful management of these tasks requires a robust PM tool. I recommend you use Jira.

6. Sign-up with a managed cloud service provider

You should focus on the design and development, and let a managed cloud service provider handle the web app platform and mobile backend. The web app needs a “Platform as a Service” (PaaS) provider, whereas the mobile app needs a “Mobile Backend as a Service” (MBaaS) provider.

I recommend you sign-up with AWS. They have impressive cloud capabilities, and you need only one AWS account.

AWS Elastic Beanstalk is their PaaS offering, providing you with the following advantages:

It handles the cloud infrastructure, networking, storage, middleware, operating system, and runtime environment.

AWS Elastic Beanstalk lets you add databases, security, DevOps, and 3rd party APIs into your app.

They have impressive application monitoring and auto-scaling solutions.

The AWS MBaaS offering is AWS Amplify, and you can get the following advantages:

Amplify addresses the cloud infrastructure, persistent storage, database, etc.

You can easily incorporate user management, security, push notification, and other key features.

3rd party API integration, scaling your app, handling the complexity arising from different mobile platforms, etc. are easy with AWS Amplify.

7. Prepare to use the Android device location feature:

A food ordering app needs to use the device location. You need to use the Android framework location APIs, as follows:

This uses the “Android.location” package.

Your app can get the last known location, receive location updates, display a location address, etc. using this framework.

Check this guide for implementing this framework.

8. Get the iOS device location framework:

You need to use the “Core Location” framework to implement the device location feature in the iOS app. Note the following relevant points:

This framework makes use of WiFi, GPS, Bluetooth, and other relevant hardware features to gather the location data.

You can use the iOS SDK that comes as part of this framework.

There is detailed documentation concerning this framework. It guides you in implementing various features like choosing the authorization level, getting the users’ location, region monitoring, geocoding, error-handling, etc.

9. Obtain a delivery logistics platform SDK/API

Food delivery is a key functionality of your app, and I recommend you use Bringg, a delivery logistics technology platform to implement this. They already have a cloud-based restaurant delivery software platform. You can get the following advantages:

Shorter time-to-delivery;

Cost reduction;

Flexible utilization of multiple fleet types;

Optimal route assignments and allocations;

Higher customer satisfaction.

You can review the following resources to implement their SDKs:

The Bringg platform overview;

Bringg developer portal documentation;

Customer SDK for Android;

Driver SDK for Android;

Customer SDK for iOS;

Driver SDK for iOS;

Bringg JavaScript SDK for the web app.

10. Sign-up for a payment gateway SDK/API

A food ordering app needs a robust payment gateway integration. I recommend you sign-up with Braintree. It’s from PayPal.

Braintree offers the following advantages:

Fraud protection;


Data security;

Global scale;

You can implement various payment methods like a card, PayPal, Venmo (in the US), etc.

You can go through their detailed developer portal documentation. It covers the following:

Using their Android SDK;

How to use their iOS SDK;

Integrating with the JavaScript SDK;

Integration guide;


11. Get the required Android push notification software

You will need to implement push notification in your Android app. I recommend you use “Firebase Cloud Messaging” (FCM) for this. Note the following relevant information about FCM:

It’s a cross-platform messaging solution for delivering messages.

FCM enables you to notify the client app that new information is available to sync.

Learn how to use it in your Android app, in “Set up a Firebase Cloud Messaging client app on Android”.

Read “Add Firebase to your Android project” for more details.

You also need to use the Firebase admin SDK. Read “Firebase admin SDK for FCM” for guidance.

12. Learn how to set up push notification in the iOS app

Use “Apple Push Notification service” (APNs) in the iOS app. Read the following key documentation to implement it:

APNs overview” for an overview of APNs.

Design guidelines to implement APNs.

Developer guidelines for working with APNs.

13. Sign-up for an SMS management solution

You need a robust SMS management solution for the food ordering app. Twilio provides robust communication APIs for SMS, and I recommend you use it. I suggest you go through the following information:

Messaging services and Copilot”, to understand how to implement the “Programmable SMS” solution from Twilio.

Twilio SDKs library, where you can get guidance for using their Android, iOS, and JavaScript SDKs.

14. Develop, test, and deploy the web app

Now that you have obtained the required managed cloud services and SDKs/APIs, you can proceed with the web app, as follows:

Use js, a popular runtime environment enabling a developer to code performant and scalable apps. Node.js is open-source, and a large developer community creates many useful tools and frameworks. JavaScript developers can experience high productivity with Node.js.

js a highly popular framework based on Node.js, and a programmer can create fast apps with it. I suggest you use it in this project.

Add a database to your app on AWS Elastic Beanstalk, by following these instructions.

Integrate the Bringg JavaScript SDK, Braintree JavaScript SDK, and Twilio JavaScript SDK.

Read “Deploying Node.js applications to AWS Elastic Beanstalk” to know how to create, test, and deploy a Node.js web app on AWS Elastic Beanstalk. The guidance covers deploying an Express.js app.

15. Design the mobile app UI
