STB Union — on a Mission to Make Finances Convenient for Everyone

STB Union, a major FinTech player, partnered with Yojji to evolve from a traditional currency exchange network into a modern financial marketplace. The project aimed to develop a secure, scalable platform for multi-currency wallets, international transfers, and digital card services, using React JS, React Native, and Java to enhance STB Union’s service offerings and strengthen its position in FinTech.

REQUEST

Develop multicurrency wallets, enable international transfers, and support digital card usage to expand the platform.

CHAllENGE

Designed architecture for a large project focusing on security. While issues were server-side, our team handled only frontend.

OUR SOLUTION

Started with transfers from Israel via international operators. Expanded to online banking: issuing VISA debit cards for payments, transfers, and online shopping.

Our solutions

Transition to Web and Mobile Platforms

We have created a full-cycle financial services platform using React JS for responsive web and React Native for mobile applications. This makes STB Union accessible on different devices with a seamless user experience.

Robust Java Backend

We conducted front-end development with a robust Java backend to ensure scalability and efficiency. This foundation allowed the platform to process large volumes of transactions securely and reliably.

Comprehensive User Experience (UX) Research

Thorough UX research into the needs and preferences of users was necessary. This drove our design and development decisions so users find the platform intuitive.

Seamless Integration with Legacy Systems

Integration with legacy systems had to be seamless in view of service continuity and the avoidance of disruptions. This integration allowed STB Union to upgrade to better technology without any loss of functionality or data from their existing systems.

Similar Cases

ValaPay

Vala facilitates direct money transfers between businesses, reducing transaction costs and creating new revenue streams. Our team handled the UI design, revamped the application’s admin panel, and built a mobile version from scratch. Ultimately, we were given full autonomy over project design and development decisions.

Payroll

Payroll is a $1.2b cloud-based solution enabling companies of all sizes to manage global payroll, facilitate direct money transfers, and oversee payment cycles. They approached us in January 2019 to build this system on their financial and legal infrastructure. Yojji led the front-end development, including design, and contributed to back-end tasks. Through close collaboration and our team’s expertise, we successfully developed an efficient payroll system from scratch.

Osu

Osu supports sole traders with a business management and payment app integrated with accounting software. The client initially asked us to design and develop the front end for their open-banking service, including a payment widget and admin system. Yojji delivered a widget and dashboard for merchants to track payments, manage users, and customize features. After a successful MVP launch, we continued developing an app to create and track payment requests. Today, we’re actively enhancing the mobile app with new features.
