Mamun Che integrated orb-models calculator support into the MLP recipes within the Quantum-Accelerators/quacc repository, enabling orb-models as a first-class dependency for static, relaxation, and phonon simulation jobs. He updated the calculator selection logic in Python, ensuring seamless inclusion of orb-models in production workflows. To maintain reliability, Mamun expanded the test suite to validate the new orb method and implemented robust error handling for missing dependencies. His work leveraged full stack development and scientific computing skills, resulting in a deeper, more flexible simulation pipeline. The integration addressed workflow fidelity and dependency management, enhancing the overall robustness of quacc’s simulation capabilities.
