Bio
UUY Jr.
What stands out for me when I think of Bruce is his out-of-box thinking, strong problem-solving skills, as well as his attention to detail. Also, he is a great team player with excellent communication skills. I learned a lot from him during our collaboration for around 1 year while at 1Qbit, and from subsequent interactions. We worked together on reinforcement learning and Bruce made significant contributions in both theory and Python coding. I think that Bruce’s current technical skills and experiences, learn-it-all mindset, and effective communication skills make him a great candidate for a role in any data science/ML team.

I worked with Bruce on a project during my first year at 1QBit. He taught me a lot about optimization, machine learning, software design, and version control. He's extremely thoughtful and patient, and is both a great teacher and a calming presence. I enjoyed our collaboration, both in code and at the whiteboard, as well as the great life conversations throughout!

Dec 2020 - Jan 2022
Worked on heuristic algorithms to solve NP-hard hardware related problems, and implemented them into a product using good software development practices.Software improvements:o Python: Improved adherence to PEP8 and google code style standards by providing support on code linting and establishing a PR checklist.o Git: Streamlined internal squash-rebase workflow by creating a training video.o Automated parallelization by using Ray on GCP (Google Cloud Platform).o Introduced joblib to cache intermediate results.Algorithmic contributions:o Invented a new data structure and algorithm to substantially improve the space complexity and meaningfully improve the time complexity of a core part of our program.o Invented a simple polynomial algorithm for an anticipated NP-hard problem.o Originated several ideas that changed our approach and resulted in an (~20%) improvement in the quality of our program’s output, in contrast to previous incremental improvements (~2%).o Provided counterexamples to quickly move on from algorithmic dead-ends.
