\- Design and build automated workflows for regulated financial operations, including transaction monitoring, compliance checks and document handling.

\- Build and extend an accounting ledger that tracks income and principal, with correctness enforced in the database and API layers.

\- Create evaluation tooling and test pipelines for AI-assisted features, including repeatable checks in CI/CD.

\- Daily use of AI coding tools in your development work.
