I have several internal applications that must exchange data smoothly with new cloud-based components, and I want these connections built with clean, well-tested code. Your job is to design and implement REST APIs in both Java and Python, wire them up to PostgreSQL for transactional storage, and index searchable content into OpenSearch so that each event is instantly discoverable. The core of the work is twofold. First, map and integrate the existing internal services with the cloud resources I will provide (IAM-secured endpoints, message queues, and object storage). Second, expose that integrated functionality through RESTful endpoints that follow standard HTTP semantics, are documented with OpenAPI/Swagger, and include unit and integration tests. When the work is complete I expect: &...

I do, however, want the codebase structured so that additional features such as automated deposit scheduling or monthly statements can slot in later without major refactoring. Scope of this engagement • Design a clean, responsive UI (React, Vue, or similar) for the calculator screen and basic account dashboard. ...
