PROFILE
Rico Haeuselmann
Rico Haeuselmann contributed to the GridTools/gt4py repository by developing the SDFGConvertible Program, enabling automated conversion of GT4Py programs to DaCe SDFGs for the dace_fieldview backend. He enhanced backend flexibility by introducing input and output field extractors, improving GTIR transform handling, and refining connectivity table management. Rico also ensured robust end-to-end validation through comprehensive Python-based testing. In a separate effort, he updated the codebase and CI pipeline for Python 3.14 compatibility, refreshing dependencies and stabilizing build processes. His work demonstrated depth in backend development, compiler infrastructure, and continuous integration, addressing both feature delivery and long-term maintainability.
