What stack do you use for full-stack web development?

Our primary stack is the PERN stack: PostgreSQL, Express.js (or NestJS), React (Next.js App Router), and Node.js. We also work with MERN (MongoDB) and can adapt to your existing architecture.

How long does it take to build a full-stack web app?

A focused SaaS MVP with auth, dashboard, payments, and API takes 610 weeks. Enterprise platforms with complex data models and integrations typically take 36 months.

Do you build the backend API and frontend?

Yes. We build the complete stack: REST or GraphQL API, PostgreSQL schema with migrations, Next.js frontend, CI/CD pipeline, and cloud deployment on AWS or Vercel.
