New business logic
New rules and states need to work with the data already in place.
Product development
New features
for a live product.
Turn an idea or recurring problem into bounded work with clear integrations, acceptance criteria, and a controlled release.

When this helps
A feature must fit the system already in use.
In an established product, even a modest feature may affect data, permissions, APIs, and familiar workflows. We define the change in system behavior, not only a screen or endpoint.
A complete specification is not required. Start with the problem, the desired outcome, and how the process works today.
02 /
Service integration
The feature depends on an external API, events, or an internal service.
03 /
A recurring workaround
The team repeatedly performs steps that belong in the product.
How work proceeds
Start with the workflow, then build.
01 /
Define the outcome
What changes for the user and how to verify it.
02 /
Map constraints
Data, access, APIs, compatibility, and related workflows.
03 /
Build a bounded release
Implementation with tests and controlled rollout.
04 /
Verify in use
Correctness, failures, and feedback after launch.
Example approach
Replace a manual approval workaround.
If approvals currently live in email and spreadsheets, first map roles, states, and exceptions. Then connect the feature to existing data and notifications. Validate both the normal and failure paths.
This illustrates a working method, not a published client case.

Questions
Do you need a full specification?
No. Describe the problem and desired outcome. Scope and acceptance criteria are agreed before implementation.
Can you work in an existing codebase?
Yes. The architecture, constraints, and release process are reviewed first; the approach depends on the project.
How is completion verified?
Against agreed workflows, compatibility with existing behavior, and post-release observations.
Next step
Describe your challenge.
Describe the system, goal, and constraints. You will receive a proposed next step, delivery format, and plan for technical oversight.
