How we found and fix slow API requests on a WordPress site

and got more than x40 speed boost after making fixes

We used WordPress as the engine and the famous LearnDash plugin to implement the Learning Management System (LMS) functionality. This combination allowed the client to develop the necessary functionality and launch a demo to test the perception by end users in a short period of time. In the process of changing the requirements, we had to abandon most of the features that LearnDash provides and restructure the approach to creating content – replacing courses with lessons and lessons with slides.

Mobile development of Mental Health App for iOS

Our client decided to attract investment in their product from one of the international venture funds. That is why they requested only the development of a basic version of the mobile application, to demonstrate the value of the product to the investors.

The main idea of the app was to help people to preserve their mental health by analyzing their heart rate over a long period of time. A special HRM from Viatom was used for this project because this device has the ability to store the HR values and sync with a mobile app through Bluetooth connectivity. Moreover, it can sync data even if the device is not connected for a long period of time. There was no time to develop detailed UX/UI and backend, so we suggested a solution that would satisfy all the client’s requirements.
