Worked on enhancing the Qiskit/qiskit-ibm-runtime repository by developing parameter expression validation for the Gen3-turbo execution path. This involved building a detection utility in Python to identify and prevent parameter expressions when Gen3-turbo is selected, addressing potential misconfigurations and improving runtime safety. Integrated the validation logic directly into the BasePrimitiveV2 class, ensuring consistent enforcement across the backend. Expanded unit test coverage to verify the new checks and guard against regressions, demonstrating a thorough approach to testing and runtime environment reliability. Focused on backend and API development, the work contributed to safer and more predictable execution within the Qiskit ecosystem.
