- Leveraged Zelvante's modular Next.js 15 architecture with pre-tested authentication and team tenancy.
- Implemented Stripe customer portal, tiered subscription webhooks, and automated usage metering.
- Built interactive data visualization components using Recharts with real-time Supabase subscriptions.
