Technical architecture design
Data model, system architecture and technology stack chosen against your specific requirements.
Custom Web Development
Custom Web Development for Requirements Off-the-Shelf Platforms Can't Meet
When a CMS or template platform can't handle your workflow, data model or integrations, we build the site or system from a bespoke codebase designed around your actual requirements.
Requirements that don't fit inside a CMS
Some businesses have workflows, data structures or integration needs that no amount of plugins or theme customisation will accommodate — forcing a platform to do something it wasn't built for usually costs more in workarounds than building it properly the first time.
- Complex data relationships or calculations that CMS plugins handle poorly or unreliably
- Multiple integrations that need custom logic, not just an API connector plugin
- Workflows specific to the business that don't map onto standard content types
- Performance or security requirements that shared CMS environments can't guarantee
Architecture designed around your requirements, not a platform's defaults
We start with your actual data model, workflows and integration needs, choose a technology stack suited to those requirements, and build a codebase that does exactly what you need — with documentation so it can be maintained and extended after launch.
What's included
Service components
Custom front-end development
Interfaces built to your exact workflow, not adapted from a template's assumptions.
Custom back-end & database design
Server-side logic and database schema designed around your actual data relationships.
Third-party & internal system integrations
Custom integration logic for CRMs, ERPs, payment systems or internal tools with proper error handling.
API development
Building APIs where the site needs to expose or consume data from other systems.
Documentation & handoff
Technical documentation covering architecture and codebase so future developers aren't starting blind.
Process
How we deliver it
- Step 01
Requirements & feasibility
Understanding the workflow, data and integration requirements a CMS couldn't meet.
- Step 02
Architecture & stack selection
Choosing the technology stack and system design against those requirements.
- Step 03
Build sprints
Iterative development with regular reviews against agreed functionality.
- Step 04
Integration & QA
Testing integrations, edge cases and performance under realistic data volumes.
- Step 05
Launch, documentation & handoff
Deployment with full technical documentation for ongoing maintenance.
Outcomes
What you get out of it
A system that fits the business, not the reverse
No workflow compromises forced by platform limitations.
Fewer fragile workarounds
Custom logic replaces stacked plugins trying to approximate custom behaviour.
Room to scale
Architecture designed for your actual growth trajectory, not a template's assumptions.
Maintainable long-term
Documented, version-controlled code that isn't dependent on one developer's memory.

FAQ
Frequently asked questions
01How do you decide if we need custom development instead of a CMS?
We assess your actual workflow and data requirements during scoping; if a CMS or platform can meet them reliably, we'll recommend that instead of over-building.
02What technology stack do you use?
We choose the stack based on the project's requirements, team's technical capability and long-term maintenance plans, rather than defaulting to one framework for everything.
03Will we be able to maintain this without you afterward?
Yes, we provide full documentation and can hand over to an in-house or other development team, though many clients keep us on for ongoing development.
04How long does a custom build take?
It varies significantly with scope — we'll give a realistic timeline once requirements and integrations are fully scoped.
05Do you build the front end and back end, or just one?
Both, and we also handle integrations end to end so there's a single accountable team rather than split ownership between vendors.
