Applications: build, test, migrate
S & M Systems Ltd designs, builds, tests and migrates applications for UK public sector and regulated organisations – whether they are public‑facing services or internal tools. We deliver secure, maintainable code with automated testing, CI/CD pipelines and documentation included.
New applications
- Requirements and discovery with both technical and non‑technical stakeholders.
- Architecture and design aligned with your existing landscape.
- Secure, maintainable code and modern CI/CD pipelines.
- Documentation and handover so your teams can own the system.
Testing and quality
- Automated tests integrated into your pipelines.
- Performance and resilience testing for critical services.
- Security scanning and code quality checks.
- Practical, risk‑based testing strategies that match your budget.
Application migrations
- Assessment of legacy systems and dependencies.
- Migration plans with rollback and contingency paths.
- Execution in controlled phases, with clear communication.
- Post‑migration tuning, monitoring and support.
We treat each application as part of a larger story, not an isolated project.
