Engineering Experience
Systems engineering, model evaluation, and backend automation across production environments.
Full-Stack Engineer & AI Evaluation Expert
- Evaluated model-generated software and responses across frontend behavior, APIs, databases, authentication, configuration, tests, and runtime environments.
- Reproduced failures, traced root causes across code and environment boundaries, classified failure modes, and verified proposed fixes with regression checks.
- Designed realistic software-engineering benchmark tasks with reproducible environments, explicit expected behavior, automated verification, and objective pass/fail criteria.
- Worked on the broken-api-deploy task and upgraded it to Harbor format for practical agent evaluation.
