- Work effectively within unfamiliar repositories and understand existing application architecture.
- Diagnose failures involving application state, API contracts, authentication, persistence, networking, and deployment.
- Develop and evaluate software solutions across multiple programming languages.
- Translate complete coding implementations from one programming language into another while preserving intended functionality.
- Review AI-generated software solutions for correctness, completeness, performance, security, and maintainability.
- Identify technical issues and recommend appropriate improvements to application code and architecture.
- Validate solutions against functional and technical requirements.
- Apply strong engineering judg
