Hey, I'm Alyssa! I'm a product-focused software engineer and applied statistician based in San Francisco. I'm currently a senior software engineer at at Pilot, a small tech company building bookkeeping and financial products for businesses.
I spent 2020 building models and software for progressive political campaigns at Deck, and I was an ML engineer at Stripe for almost five years, where I built payment fraud models and user security systems (like 2FA and account takeover protection). I've also worked in computational biology: I did a PhD in biostatistics at Johns Hopkins with Jeff Leek. A lot of my graduate work is publicly available, including papers, R packages, and talks.
