Rockstar🎓
Top SchoolKurtis Liu is a Full Stack Software Engineer with 13 years of experience specializing in image and video encoding, machine learning, and computer vision, currently based in Seattle. He pairs graduate-level expertise in ML/CV with low-level, pixel-level optimizations implemented in C++, TensorFlow, CUDA, and OpenCL, and has practical embedded-systems experience tackling race conditions and tight CPU/memory constraints. Kurtis has shipped production-grade systems at Amazon and LinkedIn and contributes to open-source infrastructure—most notably improving metrics and portable bundle management for the Apache Beam Samza runner. He also builds developer tooling like ReRe, a Java object record-and-replay project that exports Mockito mocks, demonstrating an appetite for practical developer productivity solutions. Comfortable moving between research prototypes and hardened back-end code, he brings both algorithmic rigor and systems-level pragmatism. An understated strength is his history of squeezing performance from constrained environments, a skill that informs his work across cloud, embedded, and GPU-accelerated domains.
