SServices
Ten service
areas.
Each area below sets out what the work covers, where it typically applies, what is handed over and the working principle behind it. Engagements usually combine several areas around one outcome.

Custom software development
Applications built for a specific operational need where off-the-shelf software does not match the process. Scope is defined before implementation and delivered in reviewable increments.
Suitable use cases
- Internal tools replacing spreadsheet-based processes
- Back-office systems with role-specific workflows
- Products with rules no packaged tool models correctly
Typical deliverables
- Scope document with acceptance criteria
- Source code in your repository
- Automated test suite and CI configuration
- Setup and operations documentation
Working principle
Nothing is built before the behaviour it must produce has been written down and agreed.
Web application development
Browser-based products with deliberate state handling, performance budgets and accessibility considered from the first screen rather than retrofitted.
Suitable use cases
- Customer-facing portals and dashboards
- Data-heavy interfaces with complex filtering
- Multi-role applications with permission boundaries
Typical deliverables
- Component library aligned to the design system
- Responsive implementation across device sizes
- Accessibility review notes
- Build and deployment pipeline
Working principle
Interface performance and keyboard accessibility are acceptance criteria, not later improvements.
Product design and UX
Structuring what a product contains and how people move through it, then documenting that structure so engineering can implement without reinterpretation.
Suitable use cases
- A product whose feature set has outgrown its navigation
- Workflows that generate repeated user error
- Interfaces that need a consistent system across teams
Typical deliverables
- Information architecture and flow diagrams
- Interface specifications with states and edge cases
- Design tokens and component definitions
- Content and labelling guidance
Working principle
A design is finished when an engineer can build it without asking what happens in the unusual cases.
System architecture
Deciding boundaries, data ownership, interfaces and failure behaviour for a system before code makes those decisions implicitly.
Suitable use cases
- A monolith that needs clear internal boundaries
- Multiple systems duplicating the same records
- A platform approaching a scale or compliance change
Typical deliverables
- Architecture document with diagrams
- Data ownership and interface contracts
- Trade-off analysis of the options considered
- Sequenced implementation plan
Working principle
Every architectural choice is recorded with the alternatives it was chosen over.
API and platform integrations
Connecting internal systems and third-party platforms with contracts, retries and error handling defined rather than assumed.
Suitable use cases
- Data re-entered by hand between two tools
- Third-party services needed inside an internal workflow
- Public or partner APIs exposed from an existing system
Typical deliverables
- Interface specification and schema definitions
- Authentication and error-handling implementation
- Retry, idempotency and reconciliation logic
- Integration test coverage
Working principle
An integration is designed around what happens when the other side is unavailable.
Cloud solutions
Environments, deployment paths, scaling behaviour and cost visibility set up so releases are routine and infrastructure is reproducible.
Suitable use cases
- Manual deployments that only one person can perform
- Environments that drift apart from each other
- Workloads with variable or seasonal demand
Typical deliverables
- Infrastructure defined as code
- Separated environments with promotion path
- CI/CD pipeline with rollback
- Monitoring, logging and alerting setup
Working principle
If an environment cannot be recreated from the repository, it is not finished.
Software modernization
Replacing legacy components incrementally, keeping the system in service while responsibility moves piece by piece to the new implementation.
Suitable use cases
- Unsupported frameworks or runtimes still in production
- Systems where routine change has become expensive
- Platforms blocking a required integration or compliance need
Typical deliverables
- Assessment of the current system and its risks
- Prioritised migration sequence
- Compatibility layers where needed
- Progress reporting against the sequence
Working principle
Modernization proceeds in steps that can each be stopped, reversed or paused.
Quality assurance
A test strategy proportional to risk, covering unit, integration and end-to-end levels, wired into the pipeline so results arrive with every change.
Suitable use cases
- Releases that require lengthy manual regression passes
- Recurring defects in the same areas
- Systems with critical paths that must not break
Typical deliverables
- Test strategy mapped to risk areas
- Automated suites at appropriate levels
- Pipeline integration and reporting
- Defect triage process
Working principle
Test coverage follows consequence: the paths that matter most are covered first.
Technical consulting
Focused review and written recommendation on a specific question — an architecture, a vendor choice, a performance problem or a delivery approach.
Suitable use cases
- A build-versus-buy decision that needs an independent read
- A performance or reliability problem without a clear cause
- A technical plan that needs review before commitment
Typical deliverables
- Findings document with evidence
- Options with trade-offs and cost implications
- A recommendation and its reasoning
- Follow-up session with your team
Working principle
Recommendations state their assumptions and the conditions that would change them.
Maintenance and support
The ongoing work after release: dependency updates, security patching, small changes and investigation of issues as they arise.
Suitable use cases
- Software in service with no dedicated engineering team
- Dependencies drifting out of support
- A steady stream of small change requests
Typical deliverables
- Agreed scope and response expectations
- Dependency and security update cycle
- Change log and periodic written report
- Documented runbooks for recurring tasks
Working principle
Maintenance is planned work with a defined scope, not an informal arrangement.
How engagements are scoped
One outcome, several areas
A single piece of work usually draws on design, architecture, development and quality assurance together. Scope, sequencing and acceptance criteria are agreed in writing before implementation begins, and changes to that scope are re-agreed rather than absorbed.
