Three things I build often enough to scope and quote quickly:
- A SaaS MVP in six weeks: multi-tenant data model, role-based dashboards, Stripe billing, deployed on AWS or Vercel with CI.
- A 3D product page for an e-commerce store: scroll-driven three.js scenes and product viewers wired to Shopify checkout, like Atomic Muscles.
- Billing and access retrofits: Stripe subscriptions, roles and permissions, and audit trails added to an existing React or Next.js app.
