I am a Senior Front-End Engineer at Amazon. I am the lead front-end engineer for the Amazon UI framework -- a powerful, cross-platform component framework used to generate the UI for the highest traffic pages and features across Amazon's desktop, tablet, and mobile websites and apps. I utilize HTML5, CSS, JavaScript, SASS, responsive design (RESS), Java, Ruby, Perl, Node.js, and related technologies to build enterprise-scale web frameworks, web applications, and mobile experiences. I design and write performant, extensible, and maintainable code. I interact with UX designers and researchers to implement high-quality designs, delight users, and improve the business. I take opportunities to lead in my team and organization, and have worked on projects at Amazon with a company-wide impact. I have contributed to major internal conferences with 2,000+ attendees such as WebDevCon (speaking twice, organizing once), given tech trainings in Seattle and India, and spoken about career development. I interview and help hire high-quality front-end engineers, software developers, designers, and other technical roles at Amazon.
