Guen Prawiroatmodjo is a Senior Quantum Measurement Engineer and Python-focused developer with 12 years of experience building and shipping software and hardware across the full quantum computing stack. At Microsoft he focuses on characterization, calibration and control of quantum devices, and his background spans semiconductor spin qubits, superconducting transmons and Majorana devices—from nanofabrication and low-temperature experiments to automated calibration, benchmarking and near-term algorithm development in Qiskit, Cirq and Q#. He combines research-grade experimental skills (PhD-level quantum transport work and published results) with pragmatic software engineering practices such as CI/CD and agile development. An active open-source contributor, he has improved data acquisition tooling (Qcodes), database connectors (DuckDB ODBC) and practical integrations in widely used projects like Airbyte and Microsoft Quantum samples. Based in Seattle, he also brings cross-disciplinary leadership from building LIMS and data infrastructure at Perfect Day, highlighting his ability to translate lab workflows into production-grade systems.

Contributions summary:Guen primarily contributed to the development of data export functionalities within the `qcodes` framework. Their commits introduced the ability to export data as netCDF files, integrating related configurations and dependencies. Further contributions included refactoring code related to export configuration, renaming functions, and enhancing the export feature with options such as CSV format support and improved documentation. These changes demonstrate a focus on expanding the data handling capabilities of the framework.
