Full-stack web developer with close to a decade of experience building and modernizing production web applications. I have a strong focus on React, TypeScript, and Vue/Nuxt (SSR), and I enjoy owning features end-to-end—from UI performance and accessibility to API and infrastructure work in AWS serverless environments. I work comfortably in existing codebases, coordinate directly with stakeholders and cross-functional teams, and factor legacy systems into maintainable solutions. I’m especially drawn to GraphQL/Apollo, REST API design, state management, and testing practices, plus experimentation and monitoring to improve product outcomes.
