PROFILE

Łukasz Ćmielowski, Phd

Lukasz Cmielowski developed enterprise AI solutions across IBM’s watsonx-ai-samples, unitxt, and watsonx-developer-hub repositories, focusing on retrieval-augmented generation (RAG) and agentic workflows. He introduced and iteratively refined Python modules for RAG evaluation, implemented Mistral small model support to expand classification capabilities, and delivered an Agentic SQL RAG template with IBM DB2 integration. His work emphasized maintainability, robust configuration management, and clear documentation, leveraging Python, SQL, and LangGraph. By aligning technical direction with evolving product goals, Lukasz improved repository hygiene, streamlined onboarding, and enabled scalable, cloud-deployable AI applications for enterprise data analysis and model evaluation use cases.

Month: 2024-11 — In IBM/watsonx-ai-samples, explored RAG model evaluation by introducing a scaffolding module and evaluation data structures, then deprecated and removed the module as strategic direction shifted. The work focused on maintainability, rapid iteration, and aligning with product goals; no customer-facing features were released this month, but the groundwork informs future evaluation approaches and reduces technical debt.
