Case studies

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.

Our project is a web application for managing investments across stocks, crypto, and private equity. The request was to design, develop, and launch the platform with a focus on trading logic, data integration, and user experience. Our client received a fully functional, investor-ready platform with customizable dashboards and precise analytics.

The AI-powered Virtual Fitting Room is our solution that lets users mix and match outfits and instantly see how each look fits using an AI model or a personal photo. It helps fashion brands personalize shopping, increase conversions, reduce returns, and provide a confidence-driven user experience without complex integrations.

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.

A matter of design (AMOD) is a web and mobile platform where users can redesign real apartments, manage subscriptions, save ideas, and buy furniture without switching between separate tools. Our task was to design and develop the full product: secure authentication, subscription and payment logic, AI-based room redesign, bookmarking, and e-commerce functionality.

Our Yojji team built Time Machine as an internal time tracking system because existing tools didn’t match our workflow. The web app allows our employees to log hours by project, add weekly comments, and separate billable from non-billable time. Managers got clear visibility into workload and performance. The main focus was on simplicity, so new team members can start tracking time in just a few clicks.

Our Yojji experts built a social platform for a private network of 800+ executives, entrepreneurs, and investors who meet regularly to exchange experience and solve business challenges. The platform helps members connect, organize regional events, schedule meetings, and communicate in one secure space. It’s fully synced with Salesforce data. We completed the project in four months, 1.5× faster than the original six-month plan.

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.
