Skills

Banking domain depth on top of a working engineering, cloud and reliability stack

Eight competency areas, grouped by where they are applied rather than scored. Enterprise core banking platforms (COBOL, AIX, Oracle) remain first-class skills alongside Python/FastAPI production services, AWS serverless with Terraform, fail-closed reliability engineering, data and AI, and identity and security.
