Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I’m Aaron Williams, a senior front-end and software engineer with 13+ years of experience building production web applications and distributed systems. I specialize in React, Next.js, and TypeScript, and I love owning user-facing features end to end—from technical design and accessible UI implementation to integrating REST/GraphQL APIs, improving performance, and supporting production releases. Over the years, I’ve built reusable component and design-system patterns, implemented robust authentication and error-handling flows, and created automated unit/integration/e2e test coverage to ensure quality and resilience. I enjoy collaborating across design, product, backend, platform, and QA teams in remote environments, and I’m especially interested in applying AI responsibly and pragmatically when it improves user experiences and engineering outcomes.…I’m Aaron Williams, a senior front-end and software engineer with 13+ years of experience building production web applications and distributed systems.
