I served as a mobile development team lead. The client's goal was to combine the functionality of the mobile operator and the finance functionality. At first, it was a cryptocurrency exchange service and later became a mobile bank client. We implemented both iOS and Android apps. After that, there were a lot of steps of refactoring and adding new functionality. Now the app is working in the UK.

I acted as the lead of the mobile development team. The client wanted to develop two mobile applications (iOS and Android) from scratch. The apps were implemented for English and Arabic localization. I completed the development in a few months and supported the applications together with talented developers from my team.

Gifteka is a social network from the client in the USA. The idea was to create events where users can collect money for presents. The users can add the presents they want to get to their profile. The event can be secret, so the receivers don't know which surprises they are getting.

iClouzy was a very nice social network. A lot of its ideas we now can see on Tinder. There was matching by geolocation, and we implemented messages, friends, matches, and some simple entertainment features. Unfortunately, it was closed because of a lack of budget.

A social network where you can send photos as puzzles. It included messages, friends, and audio and video messages. The network also included its own currency, puxxles. You could top up your balance using in-app purchases.
