Jonathan – React Native, Typescript, MySQL

During this third project for the educational technology platform, the goal was to perform SIS Integration, which automated the import of raw data from Student Information Systems. This allowed the system to pre-populate teacher profiles, classes, students, and parent-teacher relationships-greatly reducing manual setup time and improving onboarding efficiency.

Jonathan was in charge of the following:

• designed and implemented the data solution to connect raw SIS teacher data with Classdojo's data model;
• implemented endpoints to enable and disable rostering;
• built a sync system to "react" to changes in the SIS data and make the same changes in the school data;
• implemented a chronological job using Kubernetes to download the raw SIS data and store it in a custom data solution for later usage.

This was the second project Jonathan carried out for widely used educational technology platform. The aim was to rewrite the Android app from native technologies to React Native to improve app rating and development efficiency.

Among others, Jonathan was responsible for:

• designed the architecture of the new react native application;
• built custom design system components;
• designed an automatic analytics tracking system;
• implemented custom API endpoints to improve app performance;
• rewrote native code into reach native code;
• improved developer experience across the app;
• build a custom error handling layer to allow for better network error debugging;
• implemented CI pipelines using github actions.
