Über Cato
I help startups and teams build, ship, and maintain web and mobile products. I work end-to-end as a senior software engineer across frontend and backend, handling architecture, implementation, and deployment so teams can move fast.
I’ve delivered production systems both as the sole engineer and as part of established teams. That includes building new products from scratch, adding features to existing applications, and working on legacy codebases where things need to be improved.
I’m comfortable taking full technical ownership when needed, or plugging into an existing team and getting productive quickly. I care about building systems that are clear, maintainable, and actually usable.
