Systems built around the work
Custom software and product engineering
Design and production engineering for software products, portals and operational platforms that generic tools cannot provide.

03Domain services and APIs
04Data, integrations and observability
Who it is for
When the current system gets in the way.
Typical teams
- Teams launching a software product with real operational complexity
- Businesses whose workflows no longer fit off-the-shelf software
- Organisations modernising fragile or difficult-to-maintain systems
Operational symptoms
- Important work is split between several tools and spreadsheets
- Employees maintain manual workarounds around the current system
- The existing product is slow to change or hard to trust
- A prototype exists, but the production architecture does not
Build scope
What Tervyn can build.
The exact boundary comes from diagnosis. These are common system components, not a fixed package.
Customer and employee portals
↗Web, desktop and mobile applications
↗APIs and third-party integrations
↗Legacy software modernisation
↗Example workflow
A complete path, with ownership at every handoff.
We define the data, interface, services and exception paths together so the workflow remains observable and maintainable.
- 01User and workflow modelInput and responsibility defined
- 02Interface and permission layerValidated handoff to the next layer
- 03Domain services and APIsValidated handoff to the next layer
- 04Data, integrations and observabilityResult recorded and observable
Delivery
Built through explicit decisions.
Every stage narrows uncertainty before the next investment is made.
Diagnose
Workflow map and problem definition
Define
Scope, architecture and success criteria
Design
Interface system and tested interaction model
Engineer
Production implementation, integrations and QA
Operate
Deployment, monitoring, support and iteration
Security & ownership
Control should survive the launch.
- ✓Clear data ownership and export paths
- ✓Role-based permissions and audit trails where required
- ✓Secure development, review and deployment practices
- ✓Documentation that supports the team after launch
Buyer questions
Before we start.
01Can you take over an existing product?
Yes. We begin with a technical and product diagnosis, identify the risks worth addressing first, then define a staged modernisation or delivery plan.
02Do you build an MVP?
We build the smallest complete product that can be used and learned from. That may be an MVP, but it will not be a disposable façade with critical workflows missing.
03Who owns the code and data?
Client ownership, access, licensing and handover are defined in the project agreement. Our default is to make ownership and operational responsibilities explicit before engineering begins.
Start with the constraint
What is slowing the business down?
Tell us where work is still being copied, chased, repeated or lost. We will help determine whether the answer is better software, automation, AI or a simpler process.
