A big advantage:

• Frontend experience with React — JavaScript/TypeScript, HTML, CSS/SCSS, and the modern React ecosystem: client state (Zustand), server state / data fetching (TanStack Query), routing (React Router), and a modern build tool (Vite).
• Hands-on experience integrating AI / LLMs into real product features.
• Contract-first / OpenAPI workflow — OpenAPI 3 with code generation (openapi-generator).
• Experience integrating an identity provider such as Keycloak.
• AWS exposure (EC2, RDS, CloudWatch) and structured (JSON) logging.
