Web application development with Next.js

A website mainly presents information. A web application is software people log into to get work done: they create records, follow workflows and see data that belongs to them. A mobile app suits people who use the product on the move, every day, or need phone features such as notifications and the camera.

Many products need more than one. A common setup is a web dashboard for staff and administrators with a mobile app for customers or field teams, both using the same API and database.

Most projects fall into a few types:

• Customer and partner portals, such as the traders' room and IB portal in Forex CRM.
• Back-office and admin systems for operations, finance and support teams.
• Learning and content platforms, such as the SCORM LMS built on Next.js with WebSockets.
• Operations platforms with public-facing pages, such as shipment tracking in a cargo and courier system I architected.
• SaaS products sold to many customers from one platform.

Business web apps hold customer records, money and internal decisions, so security is designed in rather than added later. Permissions are modelled per role and per record, so a branch manager sees only their branch, and sensitive actions such as approvals, refunds or permission changes are written to an audit trail. Secrets stay out of the code, and backups are set up with the hosting so data can be restored.

Next.js lets each page be rendered in the way that suits it. Public pages that need to rank in search are rendered on the server or generated ahead of time, so they load fast and are easy for search engines to read. Screens behind a login, such as dashboards, can fetch data on the server and add interactive parts only where they are needed, which keeps them quick on ordinary laptops and phones.

Web apps are deployed to your cloud account or to managed servers, typically in Docker containers behind Nginx, on Linux or Windows Server depending on your environment. Files can be stored in object storage such as MinIO. You keep the access, the code and the deployment notes.

The quote depends on the number of user roles and screens, the workflows and integrations, whether a backend already exists, and your hosting setup. Send a short description and you get a written scope and fixed price before work starts.
