Wolt: Food Delivery

https://play.google.com/store/apps/details?id=com.wolt.android&hl=en&gl=US
Wolt is an Android application that is written in Kotlin that allows users to order food and other listings to their homes. Wolt operates in 23 countries and 129 cities. The Wolt Android application is rated 4.7-4.8 on Play Store. We are known for incredible UX, smooth animation, and clean UI. Although the application uses a lot of resources, we manage to keep the installation file small, around 11-12MB.

Zalando Wardrobe, Zircle

This is a new Zalando emerging business project that allows users to digitalize their wardrobes. It has a rating of over 4.7/5 and over 100,000 installs.

Users are able to import their wardrobe items and sell them directly to Zalando for a Zalando shopping voucher through a flat sale channel. They can also sell to other users in the marketplace to get money.

Fashionistas and inspirers can lead the fashion trend by creating their outfits and then showing them to followers.

It is the result of my research on Coroutines, a concurrency handling method in Kotlin.
