Dopplle

Dopplle is a cross-platform (iOS & Android) marketplace app that allows people to trade and exchange clothes. This project involves a highly iterative development process while maintaining reliability of a live application that is used UK-wide.

The app

The main capabilities of the app include:

• Multiple login and registration methods, includingsocial media and email
• Address search and map visualization built around the Google Maps API, allowing a user to add multiple "home" locations to their profile and search for available clothes nearby
• Adding clothes items with multiple pictures, properties (size, color, etc.) and free-type tags
• A camera-based barcode scanner that can be used to pre-populate item properties
• An elaborate Browse screen where clothes can be searched for using text, property filters and a user's current location
• Messaging, email and push notifications. Clicking on push notifications takes the user straight to the relevant item.
• Trading of clothes using either real money (via Stripe) or an in-app currency. The trade process involves multiple steps during which users have to communicate with each other and upload pictures, e.g. as an evidence of sending an item via mail.

Project and product management

At the beginning of the project, I created a set of agile processes and coached the client's team in efficient ways of giving me feedback and keeping track of new ideas in a structured way. This enables me to streamline adding of new features, from initial requirement specification to a detailed implementation plan.

I have also created a set of Quality Assurance processes based on multiple testing stages, ensuring a high quality of the released product. I manage the Google Play Store and the App Store accounts for the client, where I release test and production versions of the app through Google Play, TestFlight and the App Store.

The admin area

Alongside the app, I have delivered an admin area where the client's team can:

• Dynamically switch features of the app on and off, without needing to release a new version
• Publish announcements to all or to a selected set of users. Announcements pop up the next time a user visits the app
• Send push notifications to all or to a selected set of users.
• Change color styles and text displayed by the app
• Change what clothes properties the users can specify and what possible values each property has
• Manage and have a complete overview of users, items and trades
• Keep track of user behaviour within the app

Reusability

As a spin-off from this project, I have created a common component library that the client is able to use in other mobile app projects.

The app can also be "white-labelled" as has been used in other projects for the client.
