description: Jacek's role, expertise, and collaboration preferences for the photo-converter project
type: user

Jacek is a senior developer (or technical lead) working on the photo-converter project. Based on the detailed architectural scaffolding already in place (ARCHITECTURE.md, PIPELINE.md, MODULES.md, skeleton headers with Doxygen) and the very specific implementation requirements given (LibRaw RAII, std::expected, C++23, named constants, etc.), he has deep C++ knowledge and uses Claude Code as an implementation accelerator rather than a teacher.

Collaboration style: give complete, production-quality code. Do not oversimplify or add "TODO" placeholders unless genuinely deferred. He reads diffs — do not recap what was done.
