Moodle Upgrade and AI Integration

We need a technical partner to help stabilise and improve our Moodle platform, classroom.realenglish365.com. The site is currently on Moodle 3.11.5, unmaintained for 3 years, and unpatched since November 2023. Scope includes backup, upgrade to Moodle 4.5 LTS, PHP 7.4 to 8.3, fix gradebook and grading configuration, and install the Edwiser suite we already own. Later work includes setting up Moodle’s AI subsystem and quiz_autograde for essay marking, plus a custom progress-report plugin for Cambridge Scale scores and teacher dashboards. You should be fluent in English, comfortable with video calls, and experienced with Moodle upgrades and AI integration. This is a pay-as-you-go project with no fixed retainer.
