• Messaging (RabbitMQ, Kafka) or caching (Redis) in production.
• Docker, CI/CD pipeline ownership.

• Build data-dense React interfaces in TypeScript: AG-Grid views, TDS components, Jotai and React Query for state and server data
• Work on audit workflows, findings triage, and security group management - features with compliance consequences
