Custom Web Application (MERN)

Bespoke internal systems, CRMs and portals built on the MERN stack and handed over to you.

Overview

When off-the-shelf software forces your team to work around it, a custom system usually pays for itself quickly. We map how your business actually runs, then build exactly that: the data model, the roles and permissions, the screens your staff use every day, the reports your managers need, and the integrations that remove the copy-paste work in between. Built on MongoDB, Express, React and Node.js, deployed to your own cloud account, documented and handed over with the complete source code. Everything ships in sprints with a staging environment you can test at any point, so the system is shaped with your team rather than presented to them at the end.

Frequently Asked Questions

What exactly is the MERN stack?

MongoDB, Express.js, React and Node.js — one JavaScript language across database, API and interface. It means a smaller team can build and maintain the whole system, and developers are easy to hire later.

Can you integrate with software we already use?

Yes. We regularly integrate CRMs, accounting systems, payment gateways, shipping providers, WhatsApp Business, Google Workspace and custom legacy APIs. If it has an API or a database we can connect to it.

Who owns the code and the data?

You do, completely. The repository is yours from day one, hosting runs under your accounts, and we hand over documentation and credentials at launch. There is no licence fee and no lock-in.

Can you maintain the system after launch?

Yes — through a monthly support plan covering bug fixes, security updates, backups, monitoring and a block of hours for new features.
