Web applications
Web applications that hold up once real users depend on them.
We build browser-based products for companies that have outgrown spreadsheets, generic tools, or a first version that cannot scale — with the architecture, permissions, and data handling a growing business actually needs.
Problems this solves
Signals a custom web application is the right investment
A spreadsheet or generic tool has become the unofficial system of record for a core process.
Different teams or customer types need different permissions, views, and workflows in the same system.
An existing internal tool has become slow, unmaintainable, or too risky to change.
Customers or partners need a self-service interface instead of manual handling by staff.
The business needs a single, connected view of data that currently lives in separate tools.
What we deliver
Product and technical discovery
A clear definition of users, roles, workflows, and data model before code is written.
A maintainable architecture
Server-rendered where it matters for speed and SEO, with clear boundaries between frontend, backend, and data layers.
Role-based access control
Permissions enforced on the server, not just hidden in the interface.
Testing and documentation
Automated tests for critical paths, and documentation the team can hand over.
How the engagement works
From discovery to a maintained production system
- 01
Discovery
Define users, workflows, data model, integrations, and success criteria.
- 02
Architecture
Choose the technical approach: rendering strategy, data layer, hosting, and security model.
- 03
Build in iterations
Ship visible, testable increments rather than one large release at the end.
- 04
Launch and support
Monitor, fix, and extend the application as real usage reveals new requirements.

Security and operational considerations
What we account for by default
Server-side validation and sanitisation of all user input.
Least-privilege access for every role, checked on every request.
Security headers and a content security policy appropriate to the integrations used.
Rate limiting on public forms and endpoints.
Structured logging for failures, without recording sensitive data.
