Dimitris developed core backend systems and agent tooling for the mozilla-ai/lumigator and mozilla-ai/agent-factory repositories, focusing on API-driven architectures, robust data modeling, and automated workflows. He implemented features such as model catalog endpoints, experiment management, and agent code validation using Python, FastAPI, and Docker, while integrating technologies like Celery, Redis, and S3 for scalable processing and storage. His work emphasized maintainability through automated dependency management, comprehensive testing, and CI/CD improvements. By introducing protocol compatibility, flexible evaluation frameworks, and artifact validation, Dimitris delivered reliable, reproducible systems that improved developer onboarding, reduced manual maintenance, and enabled safer, scalable deployments.

September 2025 performance summary for mozilla-ai/agent-factory: Delivered core reliability and evaluation improvements focused on generated agent code quality, flexible evaluation prompts, and CI stability. Implemented Python syntax validation and automatic fixing for generated agent code via a CodeSnippet model, with AST-based validation, LLM-driven fixes with retries, and comprehensive artifact validation tests. Enhanced evaluation framework by making the judge model configurable, removing hardcoded webpage descriptions, and updating to a stronger default model to improve instruction following and tool usage in evaluation case generation. Strengthened evaluation tooling and CI by aligning with MCPD client, adding timeout handling, and increasing MCPD connection timeouts, boosting CI/test reliability. Overall impact: reduces syntax/runtime errors in generated agents, improves evaluation repeatability and quality, and lowers maintenance costs through more robust tooling.
