What I'm looking for

I’m looking for remote contract work where I can design and validate AI software-engineering evaluation tasks and troubleshoot backend systems, translating real engineering scenarios into reproducible tests with rubric-based acceptance, Docker-ready evidence, and objective comparison across models.

I’m a software engineer with 7 years of experience in backend development, distributed systems, B2B SaaS, debugging, and production issue resolution. I design and deliver realistic, repository-level evaluation tasks for AI systems—turning messy engineering scenarios into self-contained work items with reproducible failure conditions, verifiable expected outcomes, objective acceptance criteria, and structured evaluation rubrics.

From reproducing defects across application, database, API, and infrastructure layers to implementing and validating bug fixes, I focus on correctness, completeness, maintainability, and instruction compliance. I also build Docker-based, test-driven task deliveries; evaluate and compare single- and multi-model outputs; and create comprehensive test scenarios (edge cases, regression, concurrency, idempotency, and recovery) so results are stable, explainable, and ready for real engineering workflows.
