- In production
The product compares credit cards and recommends rewards and points from spending patterns. It also monitors cards, offers, benefits, and issuer changes with AI agents.
I own the architecture, authentication and security, the interface, and CI/CD. I use Claude and Cursor daily since July 2025, and I review changes before they merge.
What I did
- Built the platform with Next.js, TypeScript, Supabase, PostgreSQL, and GraphQL and REST APIs.
- Shipped agent-based monitoring of cards, offers, benefits, and issuer changes, using the OpenAI API.
- Added OAuth, metrics and tracing, a design system, and translation for multiple languages.
- Run CI/CD on Vercel and AWS.
