I craft products, and the interfaces that carry them
I began my journey in web development at the age of 14 by building my first website. Since then I've worked as a product engineer, full-stack engineer, team lead, and front-end architect.
My experience spans startups, small firms, and large enterprises in B2C, B2B, and OSS sectors, directly influencing businesses with multi-billion dollar revenues.
What I do
I work end to end. On the front, interfaces and design systems; behind them, the servers, databases and infrastructure that run it all. I've also shipped mobile and desktop apps, and I keep a homelab for everything else.
A good part of my career has been in security, risk and compliance. At Reciprocity I helped build GGRC, an open-source GRC platform we developed for Google, then spun out into our own product, ZenGRC. Today I'm a founding engineer on a security product.
I'm at my most useful in large, established codebases: framework migrations, performance, and the steady work of paying down technical debt.
