Microservices Architecture
Domain-driven services that scale independently, deploy on their own schedule, and keep failures contained to a single service instead of the whole platform.
- Domain-driven
- Independently deployable
- Fault-isolated
Services that scale, deploy, and fail independently.
We break monolithic systems into domain-driven services — each owned by a clear boundary, deployed on its own pipeline, and isolated from failures elsewhere in the platform. The result is a system your teams can change safely, one service at a time.
Built so one failing service never takes down the rest.
What We Deliver
Six areas of work that make up most microservices engagements.
Service Decomposition
Breaking monolithic systems into domain-driven services with clear boundaries.
Service Mesh & Communication
Reliable, observable communication patterns between services.
Independent Deployment Pipelines
CI/CD per service, so teams ship on their own schedule.
Container Orchestration
Deployment, scaling, and service discovery infrastructure.
Observability & Tracing
Distributed tracing and monitoring across every service.
Resilience & Fault Isolation
Circuit breakers and isolation patterns that contain failure.
Our Process
A five-stage engagement, from domain mapping to independent operation.
Map Domains
Identify service boundaries and domain contracts before writing code.
Design
Define APIs, data ownership, and communication patterns between services.
Build
Implement services independently, each with its own pipeline and data store.
Orchestrate
Set up deployment, scaling, and service discovery infrastructure.
Operate
Monitor, trace, and evolve services independently in production.
Fintech Application Development
Customer and back-office applications for regulated products.
Payment Systems Engineering
Payment switches, gateways, and settlement flows.
API Development
Documented, versioned APIs for partners and products.
Legacy Modernisation
Phased modernisation of core and legacy platforms.
