At ITLEO Academy, I built the backend for LeoGameAcademy, an LMS platform supporting groups, enrollment, lessons, homework review, exam grades, and student progress. I also built a REST API for a React frontend with Firebase Authentication.
I built two Telegram bots with aiogram for demo lesson bookings and staff lead alerts, and integrated Google Calendar using OAuth 2.0 and encrypted tokens. The LMS backend has 390+ automated tests.
For ITLEO Academy’s admin system, I implemented role-based access for five roles and automated PostgreSQL backups with restore checks. I deploy and maintain it on a VPS, and have fixed production issues involving CSRF and SSL renewal; the system has 300+ automated tests.
