PROFILE
Till Rampe
Till Privat developed foundational higher-category theory infrastructure for the agda/agda-categories repository, focusing on formalizing 2-cell coherence laws, monoidal unitors, and a comprehensive coequalizers framework. He applied deep expertise in Agda and type theory to refactor and modularize code, improving proof efficiency and maintainability. His work included shortening proofs through shorthands, optimizing associativity reasoning, and enhancing module boundaries for future reuse. By addressing variable hygiene, import management, and documentation, Till improved code readability and correctness. The engineering approach emphasized formal verification, functional programming, and proof assistant techniques, resulting in a robust, maintainable codebase with clearer abstractions and safer feature delivery.

May 1, 2025May 2025 focused on delivering a robust foundation for higher-category theory in agda/agda-categories, with substantial gains in both core theory and code quality. Delivered a comprehensive suite of 2-Cell coherence laws and whiskering compatibility, along with monoidal unitors/pentagon coherence variants. Built out a full Coequalizers framework (existence, triangle isomorphisms, split coequalizers, maps between parallel pairs) with functor Preservation and commutation properties. Established bicategory infrastructure including local coequalizers and monad bimodules, plus the explicit 1-category of bimodules between monads. Performed a targeted maintenance pass to clean imports, remove unnecessary comments, and tighten using/hiding rules, complemented by proof engineering improvements via shorthand notation to shorten proofs.
