Backend-focused software engineer with experience across blockchain, fintech, and open source. I've spent the bulk of my career at Rotki, building the best open-source portfolio tracker and transaction decoding tool out there. Outside of that, I've cofounded a payments product, won several global hackathons, and shipped a range of side projects in Rust, Go, and TypeScript.
