·       Deep knowledge of PostgreSQL and database performance optimization.

·       Experience with event-driven architectures and messaging systems.

·       Hands-on experience with GCP (preferred), Docker, and Kubernetes.

·       Experience with CI/CD pipelines, automated testing, and modern development workflows.

·       Strong communication skills and cross-functional collaboration ability.

Preferred Qualifications:

·       Experience in fintech, payments, or regulated environments.

·       Exposure to real-time financial systems or external partner integrations.

·       Experience with observability and production monitoring tooling.

·       Familiarity with Domain-Driven Design principles.

·       Experience with modern backend platforms (e.g., Supabase).
