AI by day.
Building for fun.
I'm an AI QA Engineer at Samsung Electronics America in Dallas, Texas. Previously, I worked on AI data at Amazon Web Services after completing my PhD.
My work spans speech recognition, multilingual datasets, language model evaluation, and test automation. I'm especially interested in making language models more efficient for Korean.
Outside of work, I've been building mobile apps for well over a decade. I enjoy the whole process: finding a useful idea, working through the details, and making something people can use every day.
