How we work
From review
to production.
We review the system, agree on a plan, and build it. Operations or handover follow the needs of the project.
Review
Review the current system, business needs, and technical risks.
OutputSystem reviewPlan
Agree on the architecture, delivery plan, and who will run the system.
OutputArchitecture and delivery planBuild
Develop the software and infrastructure with reviewed changes and documented releases.

System management
How we
manage systems.
Access, changes, backups, and ownership are agreed at the start of each engagement.
Access permissions
Agree on who needs access, what they can change, and when that access should be removed.
Change history
Review changes in version control and document releases and configuration.
Backups and recovery
Define what gets backed up, how to restore it, and where recovery procedures are documented.
Ownership and support
Agree on who handles monitoring, maintenance, incident escalation, and handover.
Each engagement defines support coverage and recovery requirements.
