Service details

What each service includes

Service 01

Custom software development

Design and implementation of web applications, internal business systems, APIs and integrations, from first specification to production release.

Typically includes

Requirements analysis and technical specification
Front-end development with React and TypeScript
Back-end services and REST or GraphQL APIs
Third-party and internal system integrations
Automated test coverage for delivered functionality
Deployment pipeline and release documentation

Service 02

Cloud infrastructure and DevOps

Infrastructure design and automation so that environments are reproducible, observable and safe to change.

Typically includes

Infrastructure as code and environment definitions
Containerised workloads and orchestration
CI/CD pipelines with automated verification
Monitoring, log aggregation and alerting
Backup, restore and disaster-recovery procedures
Access control and secret management

Service 03

Data engineering and analytics support

Consolidation of data from operational systems into models that reporting and analysis can rely on.

Typically includes

Data source review and mapping
Extraction, transformation and loading pipelines
Relational schema design and migrations
Data validation and quality checks
Reporting models and dashboard data layers
Scheduled processing and failure handling

Service 04

Quality assurance and test automation

A test strategy proportional to risk, automated so that regressions are found before release rather than after.

Typically includes

Test strategy and coverage planning
Unit and integration test suites
End-to-end browser automation
Regression runs inside the delivery pipeline
Performance and load testing
Release verification and defect reporting

Service 05

System modernisation and migration

Incremental improvement of existing systems, replacing fragile parts without stopping the business that depends on them.

Typically includes

Codebase, dependency and architecture review
Dependency and runtime upgrades
Refactoring toward testable boundaries
Database and platform migration planning
Phased cut-over with rollback paths
Knowledge capture and documentation

Service 06

Technical support and maintenance

Continuous operation of live systems, with defined handling for incidents and planned maintenance work.

Typically includes

Monitoring and health checks
Incident triage and corrective fixes
Security and dependency patching
Scheduled maintenance windows
Capacity and cost review
Periodic reporting on system health

Deliverables

What you receive at the end of an engagement

Source code in a repository you control, with commit history intact.
Infrastructure definitions and deployment pipeline configuration.
Automated test suites and instructions for running them.
Architecture notes describing components, data flows and integrations.
Operational runbooks covering deployment, monitoring and recovery.
A handover session and a written summary of known limitations.

Data centre corridor with server racks and blue status lights

Engagement and estimation

How scope and effort are agreed

Step 01

Discovery first

A short paid or scoped discovery phase produces a shared understanding of the system, the constraints and the risks before any estimate is treated as firm.

Step 02

Written scope

Deliverables, assumptions, exclusions and acceptance criteria are documented so that both sides measure completion the same way.

Step 03

Reviewed increments

Progress is demonstrated on a regular cadence, and changes to scope are recorded with their effect on time and cost.
