Services
Seven kindsof engineering work
Most engagements combine several of these. Each section describes the business need it answers, the typical scope, what is handed over, and how we work through it.

Overview
Service areas
- 01
Custom software development
Systems built for a specific process rather than adapted from a generic product.
- 02
Web application engineering
Browser-based applications for daily operational use, not brochure sites.
- 03
Cloud and infrastructure
Reproducible environments, routine deployments and monitoring that explains itself.
- 04
Systems integration
Making separate applications share data reliably and only once.
- 05
Process automation
Replacing repeated manual steps with jobs that run on their own.
- 06
Maintenance and support
Keeping a live system healthy, current and able to change.
- 07
Quality assurance and security review
Testing and review practices applied to our work and to yours.
01 — Service
Custom software development
A workflow is specific enough that off-the-shelf software forces workarounds, duplicated data entry or manual reconciliation. The cost shows up as time lost every week and as errors that are hard to trace.

Typical scope
- —Process discovery and written requirements
- —Domain and data modelling
- —Backend services, business rules and APIs
- —Role-based access and audit trails
- —Reporting and export capabilities
Deliverables
- —Source code in your repository, with commit history
- —Automated test suite and pipeline configuration
- —Database schema and migration scripts
- —Architecture and operations documentation
Working approach
We agree a scope document first, then build in short cycles that each end with software you can open and use. Priorities are reviewed at the end of every cycle, and anything cut is recorded rather than quietly dropped.
02 — Service
Web application engineering
Staff or customers need to work with the same data from different places and devices, and installing desktop software is impractical. The application has to be fast, accessible and dependable on ordinary hardware and connections.

Typical scope
- —Interface design and interaction patterns
- —Server-rendered pages and client-side state
- —Authentication, permissions and session handling
- —Data-dense views, forms and validation
- —Responsive layouts and accessibility work
Deliverables
- —A deployed web application with staging and production environments
- —Component structure and design tokens documented
- —Accessibility and performance review notes
- —End-to-end tests for the primary user journeys
Working approach
Interfaces are prototyped against real data early, because sample content hides the problems. We measure page weight and rendering behaviour during development instead of optimising after complaints.
03 — Service
Cloud and infrastructure
Deployments are manual and nerve-racking, environments have drifted apart, or nobody is certain a restore from backup would work. Growth or an audit makes the current arrangement untenable.

Typical scope
- —Infrastructure described as code
- —Build and deployment pipelines
- —Networking, access control and secret management
- —Logging, metrics, alerting and dashboards
- —Backup, restore and disaster recovery procedures
Deliverables
- —Versioned infrastructure definitions
- —Automated deployment for each environment
- —Runbooks for common operational tasks and incidents
- —A documented, tested restore procedure
Working approach
Where infrastructure was grown by hand, we document the existing setup before changing it, then migrate service by service so there is always a working system to fall back to.
04 — Service
Systems integration
The same information is entered into several systems, reports disagree depending on the source, and staff spend hours reconciling records that should already match.

Typical scope
- —Mapping data ownership across systems
- —API, webhook, file and message-based interfaces
- —Transformation and validation rules
- —Retry, error handling and reconciliation reporting
- —Monitoring of synchronisation health
Deliverables
- —Integration services with documented interfaces
- —A data mapping document naming the source of truth for each field
- —Reconciliation reports and failure alerts
- —Tests covering the agreed transformation rules
Working approach
Every synchronisation is built to be idempotent and safe to re-run. We start with one direction and one entity, prove it in production, then extend.
05 — Service
Process automation
A recurring task — a monthly report, an import, a batch of notifications — is done by hand. It consumes time, depends on one person remembering, and fails silently when it is skipped.

Typical scope
- —Reviewing the manual process and its exceptions
- —Scheduled jobs, event-driven triggers and queues
- —Document and data generation
- —Notification and approval steps where a human decision is required
- —Operational visibility into every run
Deliverables
- —Automated jobs with schedules and dependencies defined in code
- —A record of each run, its inputs and its result
- —Alerts for failures and for runs that did not happen
- —A written description of the automated process and its exceptions
Working approach
We automate the well-understood path first and leave the genuine exceptions to people, with clear handover points. Automation without visibility just moves the problem, so logging comes with the job.
06 — Service
Maintenance and support
An application is in production and needs dependency updates, security patches, small improvements and someone to look at it when something breaks — without keeping a full-time team on standby.

Typical scope
- —Dependency and platform updates
- —Security patching and vulnerability review
- —Monitoring review and alert tuning
- —Bug investigation and correction
- —Small feature work and technical debt reduction
Deliverables
- —A regular maintenance record of what changed and why
- —Updated documentation as the system evolves
- —Incident notes describing cause and correction
- —A prioritised list of known issues and improvements
Working approach
Maintenance is arranged as an ongoing agreement with an agreed scope of work and channels for reporting issues. The specific terms are settled in writing before it starts.
07 — Service
Quality assurance and security review
Releases carry more risk than they should, regressions surface in production, or a system needs an independent look before an audit, a launch or a handover between teams.

Typical scope
- —Test strategy and automated test suites
- —Continuous integration configuration
- —Exploratory and regression testing
- —Code and architecture review
- —Security review of access control, dependencies and data handling
Deliverables
- —Automated tests running on every change
- —A written review with findings ordered by severity
- —Recommended remediation steps with effort estimates
- —Improved pipeline configuration where it is part of the scope
Working approach
Findings are described factually, with the reasoning and the evidence, so your team can judge them independently. We do not certify systems or issue guarantees; we report what we found and what we would change.
Engagements
How work is arranged
Scope, timing and commercial terms are agreed in writing for each engagement before work begins. We do not publish standard prices, because the shape of the work differs too much between projects.
