Professional Summary

Quantum systems engineer specializing in cloud-native quantum computing systems, calibration automation, and superconducting quantum computer operations.

Lead developer of OQTOPUS, an open-source software stack for operating cloud-accessible superconducting quantum processors, including 64- and 144-qubit systems.

Designed and developed QDash, a calibration orchestration platform connecting calibration workflows, device health monitoring, and production quantum operations.

Experienced across the quantum system stack: device integration, pulse-level control, OpenQASM 3 execution, cloud APIs, infrastructure, observability, and user-facing services.

Expertise in Go, Python, AWS, Terraform, cloud operations, reliability engineering, and production quantum system maintainability.

Background in superconducting quantum circuits (M.S. Physics) with publications and presentations at IEEE QCE, HEART, QSMC, and international quantum software forums.
