Summary
👤
Senior🎓
Top SchoolTe-wei Tsai is a Senior Software Engineer with nine years of experience building real-time control systems and scientific software for large-scale observatory and research projects. Based in Tucson and authorized to work in the US, he has driven control-loop tuning, DDS/TCP-IP integration, and real-time Xenomai-based controllers for mirror, rotator, and hexapod systems at Rubin Observatory and LSST. His background in physical chemistry and hands-on research — including inventing a high-resolution force spectroscopy method and simulating quantum transport — gives him a rare mix of deep physics insight and pragmatic software engineering. He is fluent in model-based design (Simulink/MATLAB), C++/Rust development, and engineering UIs (Qt/LabVIEW), and has improved algorithms and CI/CD workflows to reduce compute time and increase maintainability. Known for mentoring new developers, he also bridges embedded real-time constraints with cloud-native deployment patterns (Docker/Kubernetes) to make high-precision instrumentation robust and scalable.
