Lingoda

Lingoda’s audience was expanding fast, and the existing platform needed to handle tens of thousands of learners and teachers at once. Students expected easy access to live classes, smooth booking and scheduling, and a consistent experience on any device. Teachers needed simple tools to manage lessons and communicate with students. The main challenge was to scale the system while keeping performance, reliability, and quality intact.

As more users joined, the platform risked slower scheduling times and uneven performance in different regions. The experience between web and mobile felt inconsistent, creating friction for both teachers and learners. Without addressing these gaps, engagement could drop, and the company’s reputation for flexibility and reliability would be harder to maintain.

Appolica worked closely with Lingoda to build a platform that could grow with its audience and stay dependable under pressure. The team started by mapping the journeys of both learners and teachers to pinpoint where users were losing time or context. From there, the focus shifted to improving the flow of class scheduling, simplifying teacher dashboards, and ensuring the interface worked seamlessly across devices and time zones.

The updated Lingoda platform supports thousands of concurrent users with stable performance and an intuitive interface. Learners can book or join live classes anytime, while teachers can manage lessons and track progress with ease. The new backend architecture scales automatically as usage increases, and features like Lingobot bring AI-driven roleplay exercises into the learning experience, helping students practice conversations in real time.
