Case studies

Tiger 21 Connect is a web platform for a global network of high-net-worth investors. Their engineering team used several AI coding assistants, but each developer configured them differently. None of the tools knew the project's code standards, design files, or ticket structure. Our team built one shared setup that teaches every assistant the same rules, connects them to Figma, Jira, and Confluence, and adds around 40 templates for recurring tasks. Every developer now gets the same quality of AI help, and complex bugs that once took hours to investigate now resolve up to 98% faster.

Loyal Payment is a fintech mobile app for utility bill payments. The client required a simple product that allows users to pay water, gas, electricity, and housing bills in a single interface, track a payment history, and manage various addresses. Our team designed and developed the mobile app, created a scalable structure for multiple services, and simplified payment flows to increase payment transparency and decrease manual steps.

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.

Payroll is a $1.2b cloud-based solution that enables companies to manage global payroll, oversee payment cycles, and process direct transfers across countries. They approached us to build this system on their financial and legal infrastructure. Yojji led the frontend development and design and contributed to backend tasks. Within two months, users completed their first payroll transactions, and the platform continued to expand with new features.

An Australian financial company partnered with us to build a mobile investment application that allows parents to create separate accounts for their children and invest regularly. The platform supports automated payments, stock price tracking, and portfolio monitoring to accumulate capital over time. Within three weeks, we delivered a fully functional MVP with core investment logic and secure data exchange with backend systems.
