Custom Web App Development with Next.js

I design and build custom web applications with Next.js, React, TypeScript, Node.js, and Laravel — including authentication, dashboards, APIs, database design, payments, and deployment. I focus on practical business systems: clean architecture, responsive UI, weekly progress demos, full code ownership, and handover documentation.

FAQ

Questions, answered honestly.

  • A focused dashboard or business app usually takes 3–6 weeks. Larger MVPs and multi-role platforms can take 6–10+ weeks. Timeline depends on roles, integrations, data model complexity, and how ready the content/design requirements are.

  • Yes. The client receives the repository, hosting handover, deployment notes, and documentation. No lock-in.

  • Yes. I can add features, fix bugs, refactor, improve performance, or stabilise existing Next.js, React, Node.js, Laravel, and WordPress-based systems.
