Software Development · Backend
Business logic that holds under load.
Data model, rules, APIs and background processes - the part that decides whether the system survives growth.
When clients usually bring us in
- the existing system no longer keeps up
- the work happens in spreadsheets
- data is duplicated across systems
- you need a new application
- you want to modernise an old system
- you're building a new digital product
What this means for you
- Fewer spreadsheets and manual status updates.
- Less duplicated data across systems.
- One view of the process for management and the team.
- A system that grows with the company.
- Less dependence on the one person who knows how it works.
What we cover
- data model and migrations
- business rules and validation
- APIs for internal and external clients
- background jobs and queues
- performance and caching
- logging and traceability
- security controls
The data model is the most expensive decision
An interface can be changed in a week. A data model with three years of records and two integrations running on it takes months to change. So we spend more time on it at the start than seems necessary.
- what one record is and who owns it
- what may be deleted and what may only be archived
- change history, where you will need it
- migrations that can run without downtime
- rules enforced in the database, not only in the interface
What happens when something fails
A system's reliability shows not when everything works but when an external service stops answering or a user clicks the same button twice. We handle those during development, not after the first incident.
- retries that do not create duplicate records
- background jobs for anything longer than a few seconds
- a log that says what happened and to whom
- an alert to the responsible person on failure
- backups that have been restored at least once as a test
How we build the system
Architecture
We define the data model, modules and system boundaries before development, so later growth doesn't require a rewrite.
UX/UI
You approve the user journeys and a prototype of the key screens before any feature is written.
Frontend and backend
The interface and the server side are built to one standard: readable code covered by automated tests.
Integrations
Connections to ERP, CRM, document systems and registries, with logging and retries.
Data
Migration, cleanup and data quality rules, so the new system doesn't inherit the old errors.
Security, quality, rollout
Security
Authentication and permissions, encryption in transit and at rest, an audit trail and a review before go-live.
Testing
Automated tests, regression and acceptance testing against your criteria, not ours.
Deployment
Separate environments, phased release and the ability to roll back within minutes.
Handover
Code, access, documentation and team training. The system stays yours.
Maintenance
An agreed response time, monitoring and a monthly allocation for enhancements.

FAQ
Can you extend our existing system instead of building a new one?
Yes. We first look at what is worth keeping; we propose new development only when modernisation isn't enough.
Who owns the code?
You do. At handover you receive the code, the access and the documentation.
What happens after go-live?
With an agreed response time, monitoring and a monthly allocation for enhancements.
