What I'm looking for

I seek senior frontend/engineering roles where I can lead accessible, high-performance web experiences, mentor teams, and drive technical excellence in cross-functional environments.

I am a Senior Software Engineer with 10+ years building scalable web applications and browser-integrated features, focused on performance, accessibility, and exceptional user experience.

I specialize in front-end development using React and TypeScript, and I have architected modular design systems, reusable Web Components, and responsive accessible UI components following WCAG guidelines.

My background includes full-stack work with Node.js and Python, cloud deployments on AWS, and building internal tools, dashboards, and customer-facing platforms that improved load times, core web vitals, and developer productivity.

I collaborate closely with UX designers, backend engineers, and product managers, mentor junior engineers, and emphasize testing, CI/CD, and iterative delivery to produce reliable, maintainable software.
