About

I am a Senior Frontend Engineer with 8 years of experience building scalable, performant, and user-centric web applications using Angular (v4–20), JavaScript/TypeScript, React, and modern frontend architecture. I specialize in frontend modernization, performance optimization, and creating UI experiences that directly improve customer satisfaction and business outcomes. At Blackhawk Network, I led the migration of multiple enterprise Angular applications from v9 to v20, implementing standalone components and signals. This modernization initiative reduced build time by 50% and build size by 20%, significantly improving developer productivity and app performance. I have a strong track record of driving impact beyond feature development — automating workflows, improving CI/CD pipelines, mentoring junior engineers, and collaborating across product, UX, DevOps, and backend teams. I also enjoy improving frontend performance through lazy loading, code splitting, change detection optimization, and bundle analysis. Key Areas of Expertise: • Angular (v4–20), RxJS, NgRx • React.js, JavaScript/TypeScript • UI performance & frontend architecture • AWS (Lambda, S3, CloudFront, ECS), Docker • CI/CD (Jenkins, Bitbucket), Git • Accessibility (a11y), WCAG • Mentoring, code reviews, cross-team collaboration I’m currently looking for opportunities where I can contribute to high-impact frontend development, modernize UI architecture, and help engineering teams ship faster, cleaner, and more scalable user experiences.
