The Challenge
Aurora was struggling with a legacy monolithic architecture that caused 15+ second page loads and a complex onboarding flow leading to a 60% user drop-off rate before KYC completion.
- Migrating a live PostgreSQL database with zero downtime.
- Ensuring SOC2 and PCI compliance throughout the stack.
- Redesigning a dense, data-heavy dashboard to be intuitive for non-technical users.
Architecture & Solution
We decoupled the monolithic application into a modern Next.js frontend communicating with scalable Node.js microservices. The entire user onboarding flow was redesigned in Figma and engineered to feel instantaneous using React's optimistic UI patterns.
The application relies on Vercel for Edge-network frontend delivery, interfacing with an AWS Application Load Balancer routing requests to containerized Node.js services. Data is strictly cached using Redis to prevent database bottlenecks during peak trading hours.
Business Impact
Key Outcomes
- Increased successful KYC completions by 140%.
- Reduced cloud infrastructure costs by 35% through container optimization.
- Secured $12M Series A funding following the V2 launch.
