WIUNIX / SOFTWARE ENGINEERING
Software engineering for your business.
Build web applications, APIs and integrations—or improve an existing codebase—with testing, delivery automation and operating needs built into the work.
DEFINE THE SOFTWARE CHANGE
Begin with the task your users need to complete.
Tell us what people need to do, what the current system makes difficult and which services or data it must connect to. We turn that context into an agreed application boundary and behavior that can be checked. The stack follows the work and the team’s constraints.
A new application
Define the workflows, roles, interface states and core data model before building the selected frontend and backend. Keep important acceptance scenarios visible from the start.
An existing codebase or integration
Review the architecture, dependencies, tests and deployment arrangements. Refactor or replace selected parts when justified, while protecting existing behavior and integration contracts that still matter.
ILLUSTRATIVE APPLICATION BOUNDARY
A request crosses more than a screen.
The user interface
Show usable states for entry, validation, progress and failure. Preserve keyboard access and clear feedback for the user.
Application and API
Define input and response contracts, enforce permissions, validate business rules and handle errors consistently.
Data and connected services
Keep storage changes and external calls predictable. Decide how retries, duplicate requests and unavailable dependencies are handled.
Example boundary only. Architecture and test cases are selected for the actual application, not copied as a universal design.
Quality comes from reviewable changes
Keep code changes understandable, review dependencies and add tests around the behavior being changed. Unit, integration and user-flow checks serve different purposes; choose the mix according to risk and the agreed scope.
Modernize without losing the working parts
A legacy system does not always need a complete rewrite. Identify the parts causing operational or delivery problems, define compatibility constraints and change a manageable boundary with evidence that essential behavior is retained.
FROM CODE TO AN OPERABLE SERVICE
Make delivery repeatable and issues diagnosable.
Delivery automation and environments
Build CI/CD around the application: repeatable builds, relevant checks, controlled configuration and a known deployment and rollback path. Separate environments and secrets appropriately. Automation should support review and recovery rather than conceal changes.
Logging, health and ownership
Include useful error handling, health signals and operational references. Decide what is logged without exposing secrets or private content, who responds to a failure and how the team can reproduce or diagnose an issue.
Scope, acceptance and handover
Agree the deliverables, checks and responsibilities before implementation. The handover should connect code and deployment references to the people who will maintain the application.
Can an existing application be improved?
Yes, an engagement can focus on selected architecture, integration, testing or delivery problems. We first need enough context and authorized access to assess the codebase, dependencies and current deployment. The review determines a realistic scope.
What evidence supports acceptance?
Use agreed functional scenarios, relevant tests and deployment checks, with known limits and unresolved items recorded. A successful build alone is not proof that a user workflow or external integration works.
Does development include ongoing support?
Ongoing maintenance and support require an agreed service boundary, responsibilities and coverage. They are not automatically included by a development-page description. Discuss them alongside handover and release ownership.
Start with a high-level summary of the workflow, existing system and intended change. Keep code secrets, credentials and private records out of the public contact form.
