Enrico enhanced process modeling capabilities in the aiplan4eu/unified-planning repository by refactoring action classes to use a shared mixin for instantaneous actions and events, improving code maintainability and expressiveness. He extended the PDDL writer to support process definitions, enabling more accurate process-driven planning and smoother integration of new models. Using Python, Enrico focused on software development, refactoring, and unit testing to address both feature development and bug fixes. He stabilized process-related tests by correcting object assignments and test behaviors, which reduced regression risk and improved reliability. The work demonstrated thoughtful engineering depth within a focused, high-impact codebase.
