Hi, my name is Thom Dixon.
I love building things.
I’m a software engineer based in Seattle with over 7 years of professional experience and an additional 6 contributing to open source projects as a hobby.
My time at both small startups and large corporations has enabled me to become a proficient full-stack developer, but secure distributed systems and infrastructure are my specialties.
