Web apps that scale

Dashboards, internal tools, and SaaS products built on a modern, type-safe stack (Next.js + TypeScript + PostgreSQL) that stay fast as your data and team grow.

  • Next.js + TypeScript
  • Postgres + Drizzle / Prisma
  • Stripe, Resend, S3, auth ready
Who it's for

Teams replacing spreadsheets or a no-code tool they've outgrown, and founders building a SaaS from scratch.

What's included
  • Auth, roles, and billing (Stripe) wired in from day one
  • A Postgres data model designed to last, with migrations
  • Responsive, accessible UI on a real design system
  • Background jobs, email, and the integrations you need
  • CI/CD and a codebase another team could pick up
Timeline

A usable MVP in about 4–6 weeks; larger platforms grow in milestones.
