Instant payment app

A user-friendly mobile application for instant payments and money transfers. An app through which a user can manage all finances via one application — pay for services from a mobile phone account, from a wallet account, or attach a card from any bank.

Project background

The coronavirus pandemic forced big and small businesses to adapt to unprecedented circumstances in 2020. Technological solutions offered a variety of options to both support end users and help businesses overcome the negative economic impact of the pandemic. The telecommunication industry was no exception. 

According to Statista research, in 2021, technology spending in the telecommunication services industry grew to 1.45 trillion U.S. dollars, with an increase of nearly 5% from 2020. 

Our client, a well-established UK telecommunication company, was looking for a reliable software vendor to help develop native mobile applications for iOS and Android users. This instant payment app included integration of all telecom-related finance operations into one solution for customers’ comfort.

Business needs

Employee testimonial

Maksym Spasybin Android Developer

It was one of the most significant projects I had ever worked on. The huge development team was divided into small feature teams with a few developers for each platform. Every team had its responsibility scope: developing new features and supporting/reworking old ones. I really enjoyed working there because of the friendly and experienced people. Also, the technology stack was the most modern in those days, and we cared about reworking the old deprecated things.

Let’s bring your idea to
life together!
