- Experience integrating external providers via REST, including timeouts, provider-side statuses, delayed reversals, and 'our side / their side' reconciliation
- Strong PostgreSQL beyond CRUD: transactions, isolation levels, unique constraints, locks, indexes, and EXPLAIN

- Active use of AI agents in development, with practical understanding of spec-driven workflows and harness building
