Sam Guyette

Software Engineer

I've built services at the intersection of finance and software, with experience ranging from fast-moving fintech to large-scale platforms. I’ve contributed to designing systems that handle high throughput and enjoy the tough problems that come with scale. I'm interested in building distributed systems that are reliable, resilient, and built to last.
