Implement data access layers using Entity Framework Core against PostgreSQL

Build and integrate RESTful APIs as part of the broader enterprise system

Review AI-generated code critically - assessing correctness, security, performance, and adherence to architectural standards

Write and maintain automated tests using xUnit or NUnit, upholding a strong test culture throughout the project

Work within GitHub Enterprise Cloud CI/CD pipelines, ensuring code quality gates and deployment standards are met

Collaborate closely with fellow developers, the project architect,



and business analyst to deliver against requirements

Maintain clear, consistent coding standards across a greenfields codebase
