Test infrastructure: Testcontainers with real PostgreSQL (60s timeout), parallel test isolation (per-worker schema), flaky test quarantine, test data seeding patterns, ephemeral test databases, CI database setup. Use when setting up database testing, managing test isolation, improving CI test reliability.

- Setting up database tests with real PostgreSQL (not mocks)
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Designs, implements, and audits WCAG 2.2 AA accessible UIs for Web (ARIA/HTML5), iOS (SwiftUI traits), and Android (Compose semantics). Audits code for compliance gaps.
