Software Engineer

I write the code that makes eBird work. As a birder, I find it rewarding to work on a product that I (try to) use every day, and has brought me a lot of joy.

After graduating from Bowdoin College with a degree in Mathematics and Russian, I started watching birds and working as a software programmer. I worked in NYC for two years before moving to Moscow where I continued programming, birdwatching, and improving my Russian. After the war broke out between Russia and Ukraine in 2022, I moved back to the United States and found the Cornell Lab of Ornithology.

Spark Bird

My spark bird was a Snowy Owl, when I overheard some professors talking about twitching one on the Maine coast, and I googled the bird and found out Hedwig was real.
