- Contribute to member-facing web (TypeScript, React, Next.js) and support iOS and Android teams on API contracts and integration debugging.
- Architect PostgreSQL schemas (RDS/Aurora), write Alembic migrations, and optimize queries; utilize Redis for performance optimization.
- Implement async workflows with Celery, RabbitMQ, and Redis for webhooks, notifications, and background processing.
- Monitor and debug production systems using Datadog and Sentry.
- Write pytest and frontend tests; update Playwright E2E when product flows change.
- Contribute to GitHub Actions CI/CD for automated testing and safe deployment.
