Case studies

StudyHall is a web and mobile learning platform for structured study and exam preparation. It combines AI assistance, grammar practice, and teacher-led assessments to help students work with complex materials more efficiently. Our client got clear tools for educators to track progress and understanding in one system.

Zuzzle is an online learning tool for organized study of foreign languages and academic disciplines. The product helps students prepare for exams. They have tests, exercises, learning data, and planning tools all in one interface. The Yojji team created this e-learning platform as a scalable system that allows users to schedule daily study activities across desktop and mobile devices, track progress by subject, and examine performance trends.

ExpertsNow is a European platform where companies can create vacancies, review pre-selected expert profiles, track every hiring stage, and coordinate interviews. The Yojji team defined the product flow, designed the interface, and developed the web and mobile applications. Our client got a working two-sided system that helps companies manage their hiring pipeline and allows experts to respond to new roles in a few clicks.

The client needed a rental app that allows users to easily book, unlock, and pay for scooters, e-bikes, and e-motos. In just 5 months, our team delivered a fully functional, scalable urban rental app and admin system. It helps optimize logistics, reduce maintenance costs, and scale their services across different cities.

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 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.

Avenue tasked us with creating a platform for large companies that allows employees to set development goals, schedule lectures, receive notifications, and provide feedback. Using Scrum with two-week sprints, our PM ensured smooth communication and quick issue resolution. After launching the MVP, we provided biweekly updates, efficiently incorporating client feedback and new features.
