WeDo assigned a dedicated team, and I designed the architecture and led the backend. Laravel 9 serves the API with Sanctum auth, WebSockets for messaging and notifications, FFmpeg transcoding to HLS and PDF invoices; a Vue 2 SPA brings a TipTap post editor, resumable tus uploads and an HLS.js player. Payments run through Stripe and USDT on Tron, media sits on Cloudflare Images and S3, and everything deploys to Kubernetes on AWS via Terraform. After launch we iterated on onboarding and sign-in using analytics.
