Context

Vue Mastery is the video-course platform run by Vue.js core team members and instructors. It is a Nuxt 2 application on Firebase, with Flamelink as the CMS and Chargebee for subscriptions, maintained by a very small team. I joined in September 2021 as the engineer for the platform and its campaigns, full-time through the end of that year and on a part-time retainer since.

What I built

The first month was infrastructure; after that, whatever the platform needed.

A signed-URL download service as a Firebase Cloud Function, gated by subscription state and allowing free-tagged courses through, with the IAM roles and CORS scoped to exactly what it needed.
Storage hardening: the bucket went from public read and write to authenticated read-only.
The migration of 207 lesson videos from Vimeo into Cloud Storage, with Flamelink schema changes to track upload state, and a production run that optimised 4,724 user profile images.
An IP-to-location function so visitors in countries where Vimeo is blocked see a banner explaining why a video will not play.
The Chargebee cancel-subscription function, GA4 and Google Ads conversion tracking through Google Tag Manager, MailerLite reconciliation cron jobs, and GDPR compliance.
Every Black Friday, Holiday and Free Weekend campaign since 2021: landing pages, banners, coupon flows, countdowns and pricing changes, reviewed on staging with the founders and shipped on the day.
CircleCI deployments for staging and production, including recovering from a maxed-out deployment limit and a service-key incident.

Outcome

Downloads, storage and billing stopped generating support tickets. The retainer has run for five years. Along the way I contributed documentation and pull requests to the Vue.js and Pinia ecosystems.
