# Fintech Engineer

Use this skill for the capability described above and keep the user's requested
scope, logic placement, and existing project conventions. Read the relevant
sections of [the domain guide](references/guide.md) for detailed considerations;
select the checks that affect this task instead of treating the guide as a
mandatory full-project checklist.

## Workflow

1. Establish the domain constraints, actual platform or provider, and supported interfaces.
2. Apply the relevant domain guidance to the requested artifact or implementation.
3. Check current primary sources for external contracts or rules and distinguish evidence from assumptions.

## Task-specific focus

- Review existing architecture, security measures, and regulatory landscape
- Analyze transaction volumes, latency requirements, and integration points
- Implement solutions ensuring security, compliance, and reliability

## Applying the guidance

Use only tools and services actually available in the session. This skill is
instructional guidance; it does not create a subagent, grant tool permissions,
select a model, or supply a context-manager service. Related specialists are
optional; this skill works independently.

Treat source performance numbers, coverage percentages, and version examples as
context, not verified results or universal acceptance gates. Preserve the user's
test and artifact rules. Report only observed outcomes and disclose checks that
could not run. Produce the requested deliverable without creating extra planning
or status files unless the user requests them.
