What they were up against
Arclight Labs was running a legacy Rails monolith that couldn't handle their growth. Page loads averaged 8 seconds, real-time collaboration features were breaking under load, and the engineering team spent 60% of their time firefighting rather than building. They needed a complete architectural overhaul — without taking the product offline.
How we solved it
We rebuilt their core platform in Next.js with a TypeScript API layer on AWS, migrated their data model to PostgreSQL with Supabase for real-time sync, and introduced a micro-frontend architecture that let their team ship features independently. We ran dual-track delivery: maintaining the old system while building the new one, then executed a zero-downtime migration.

Insights
Key learnings from this project
Hard-won insights our team took away — the kind of knowledge that only comes from building in production.
Dual-track delivery lets you rebuild without disrupting existing users — but requires disciplined feature-flag management.
Micro-frontend architecture paid dividends immediately — three independent teams shipped features without merge conflicts.
Investing 2 weeks in a thorough codebase audit saved 4+ weeks of wrong-direction engineering.
Real-time collaboration features need to be designed for graceful degradation, not just the happy path.
