Redação Online's core ed-tech platform served thousands of active students and teachers daily, so it needed a real-time overhaul — better performance, mobile-first design, live data — without any disruption to people actively using it.
I led the incremental migration to Next.js App Router with SSR, ISG, and Server Components, built with TypeScript, Tailwind CSS, WebSockets, and Chart.js, and created a Storybook library documenting 45+ UI components to speed up the team's day-to-day work. I combined long polling and WebSockets for live charts and real-time updates, applying mobile-first and local-first patterns along the way.
Highlights
- Built a Storybook library documenting 45+ UI components to speed up team development
- Combined long polling and WebSockets to power live charts and real-time updates
- Applied mobile-first and local-first patterns across the v2 platform
- Reached 95+ Google Lighthouse scores with zero downtime during rollout
Challenges
- Migrating a platform with thousands of daily active users without any downtime
- Delivering real-time analytics and messaging without hurting page performance
- Rolling out changes incrementally to avoid disrupting active students and teachers mid-session
