Jan 2022 – Present
I am a full-stack software engineer at GRAIL, where we are building a blood test to detect early-stage cancer by sequencing short segments of DNA from the bloodstream (cell-free DNA). I work on the software team responsible for handling all sample and reagent data. In particular, we provide an internal web app written in Go and React that the wet lab uses to automate all batch processing and track all sample and reagent data, but which also interacts with many other parts of the data ecosystem via various APIs.
