Joseph Kamien
Senior Software Engineer • Phoenix, Arizona

Full-stack engineer who thinks in systems, not silos.

I build modern web applications with React and TypeScript, backed by well-designed APIs and relational databases. I care about scalability, performance, clean architecture, and codebases that are easier to maintain next year than they are today.

How I Work

I'm comfortable across the stack, with a natural lean toward web-first frontend work. That said, I regularly contribute to backend services, API design, data modeling, deployment workflows, and architectural discussions.

I enjoy refactoring legacy systems, improving development pipelines, mentoring teammates through code review, and collaborating closely with product and design to ship meaningful features at scale.
