Modular systems that can evolve without becoming fragile or over-engineered.

Custom applications for businesses outgrowing spreadsheets and workarounds

Most businesses reach a point where off-the-shelf software no longer fits. Spreadsheets multiply, processes become inconsistent, and work slows down.

mjnx designs and builds custom applications for startups and small businesses in Lancashire and across the UK — tools that bring clarity, structure, and control.

Common problems we solve

  • Too many disconnected tools
  • Manual admin and duplicated work
  • Spreadsheets acting as databases
  • No clear visibility into operations
  • Systems that only “one person understands”

What we build

  • Client portals and dashboards
  • Internal operations systems
  • Booking and scheduling tools
  • Admin panels and management interfaces
  • Automation and integrations between services

How we work

  1. Understand the process
    What happens today, what must improve, what must not break
  2. Define the MVP
    Start with the smallest system that delivers real value
  3. Design for clarity
    Interfaces people can use confidently
  4. Build and iterate
    Deliver in stages, improve based on usage

What “bespoke” really means

  • Your terminology, not generic labels
  • Your workflow, not forced processes
  • A system your team actually wants to use

If your business has outgrown generic software, we’ll help you build something that fits.

Hosting & ongoing support

We don’t just build and disappear.

For websites, ecommerce platforms, and custom applications built by mjnx, we offer optional hosting and ongoing support — so what we build stays fast, secure, and reliable over time.

What this includes

  • Managed hosting configured specifically for your project
  • Security updates and dependency maintenance
  • Monitoring and uptime checks
  • Backups and recovery options
  • Sensible, human support — no ticket black holes

A focused approach

We only host and support projects we’ve built ourselves.

That means:

  • no inherited mess
  • no guesswork
  • no generic “one-size-fits-all” hosting

Everything is set up to suit the system we’ve delivered.

How support works

Support is typically provided as:

  • a monthly support & maintenance plan, or
  • an agreed block of time for updates and improvements

We’ll always be clear about what’s included and what’s not — no surprise invoices.

If you’re looking for a long-term technical partner rather than a one-off build, this is where most clients see the biggest value.

For custom applications, ongoing support allows us to add features, improve workflows, and keep the system aligned with how your business changes over time.
