Backend systems and APIs
We build the systems your applications depend on — APIs, services and data layers — so your web platforms, apps and integrations have something reliable underneath them.
In short
Backend development is the construction of the parts of a system users never see: the data model, business logic, and the interfaces other systems call. It is where correctness, security and performance are actually decided, whatever the interface on top looks like.
A good fit when
- Several applications need the same data and the same rules
- Partners or other systems need controlled access to your data
- Business logic is currently duplicated across spreadsheets and applications
- Reporting is unreliable because data is spread across disconnected systems
Not the right fit when
- A single small application with no other consumers — the extra layer adds no value yet
- The need is to connect existing ERP systems, which is integration work rather than new services
- Requirements are still unclear enough that the data model would be guesswork
- An existing platform already provides the API you need

What we build with Backend Development
- APIs that let your own applications and partners read and write data safely
- Services that carry business rules so logic is not duplicated in every interface
- Data models designed for how the business actually reports, not just how it stores
- Scheduled jobs for reconciliation, reporting and data movement
What you gain
One place for the rules
Business logic lives in one service rather than being reimplemented differently in every app.
Built to be operated
Logging and monitoring are part of the build, so failures are visible rather than discovered by users.
Ready for what comes next
A documented API means the next application can be added without rebuilding the foundation.
How it compares
| Consideration | Shared backend service | Logic inside each app | Direct database access |
|---|---|---|---|
| Rule consistency | One implementation | Diverges over time | None enforced |
| Security control | Enforced centrally | Repeated per app | Very hard to constrain |
| Adding a new app | Reuses the API | Reimplements the rules | Another direct dependency |
| Change safety | Versioned contract | Change each app | Breaks silently |
| Initial effort | Higher | Lower | Lowest |
A shared backend against the alternatives.
How we implement it
Model the business entities
Define the real objects and relationships before designing endpoints around today's screens.
Design the contract
Agree the API shape with the teams who will consume it, before it is built.
Establish security boundaries
Decide authentication, authorization and least-privilege access up front rather than layering it on.
Build with observability included
Add logging, metrics and health checks as part of the build so the system can be operated.
Test the edges
Verify behaviour under bad input, partial failure and concurrent access, not only the happy path.
Document and version
Publish the contract and a versioning policy so consumers can rely on it as it evolves.
Limitations to plan for
- An API cannot improve data that is wrong at source
- Performance depends on the underlying data design; poor structure cannot be optimized away later
- Versioning is a long-term commitment once other systems depend on your API
- Backend work is invisible to stakeholders, which makes progress harder to demonstrate
Common mistakes
- Designing the data model around today's screens rather than the business entities
- Exposing internal database structure directly as an API
- Leaving logging and monitoring until after the first production incident
- Changing an API without versioning once other systems already call it
Security and governance
- Authentication and authorization enforced at the service, not only in the interface
- Least-privilege access so each consumer reaches only what it needs
- Input validation at the boundary to prevent malformed or hostile data entering
- Audit logging of who changed what and when, retained for review
