Aaron Hsu
I'm a junior at Duke interested in the design of low-latency, high-throughput backend systems. I have experience working on ETL pipelines at growth stage startups and I enjoy thinking about algorithmic problems.
Right now, I'm on the Data Platform team at Ramp working on their internal feature store for ML decisioning models.
In my free time, I like to explore new tech, play with fire, and try different restaurants.
