Sengthai Heng

About Me_

I am a quantum software engineer, quantum-classical compiler researcher, and guitarist with a strong focus on software development, qubit plane architecture, and quantum-classical compiler constructions and optimization. I am leading the team in developing a quantum compiler for optimization for IDP Structure Prediction in the Quantum Computing Lab.
In my previous role, I worked as a skilled IT instructor and developer with a broad range of experience designing and developing web and mobile applications. My subset skills include UI and UX design, analytical, and structured thinking. I am open to acquiring new knowledge.
