Custom Java development when APIs are not enough
When an integration needs more than configuration, our engineers build the missing pieces: Java and Spring Boot microservices on Kubernetes, connectors and custom policies, to the same standards as the rest of your platform.
Our approach
- 01
Scope
Agree what must be custom and what the platform already covers.
- 02
Design
Service boundaries, contracts and data models reviewed with your architects.
- 03
Build
Java and Spring Boot microservices with tests, code review and CI/CD.
- 04
Hand over
Documentation, runbooks and knowledge transfer to your team.
Expertise
Java and Spring Boot
Microservices and back-end components built with Spring Boot.
Kubernetes microservices
Containerised services running on Kubernetes and Red Hat OpenShift.
Connectors and policies
Custom MuleSoft connectors and gateway policies, including Rust PDK policies.
Team extension
Engineers who join your team to add capacity on integration-heavy projects.
Outcomes
- No gaps
- Custom pieces where platforms stop.
- Maintainable
- Tested, reviewed code your team can own.
- Cloud-native
- Containerised and ready for Kubernetes.
- Flexible capacity
- Engineers when you need them.
Frequently asked questions
What technologies do you use for custom development?
Mainly Java and Spring Boot for microservices, containerised and deployed on Kubernetes or Red Hat OpenShift, alongside MuleSoft and Apache Camel for integration.
Can your engineers join our team?
Yes. We strengthen internal IT teams with Java and integration engineers who work within your processes and tools.
Do you build custom MuleSoft components?
Yes, including custom connectors and API gateway policies, for example Rust PDK policies for per-operation authorisation on MuleSoft Omni Gateway.
