Adam Kiryk
Frontend Engineer
I’m a front-end engineer with over twelve years’ experience in the industry, first as a UX and UI designer, then as a developer. I’m passionate about performance, stability, and accessibility, and I love creating great user experiences.
Sound good? I also write and speak clearly about my work. I thrive in a collaborative environment. And I love learning new things.
Background
I’ve been a front-end engineer at Wayfair since 2018, where I create solutions to critical business needs using technologies including React, Next.js, TypeScript, JavaScript, Node.js, TurboRepo, Buildkite, Cypress, webpack — and of course HTML, CSS, and git.
From 2011 to 2017, I worked at NPR, where I combined the roles of front-end developer and user-experience designer, and created a variety of websites and online tools for member stations.

Wayfair Wedding Registry
2021 – 2022 As the senior front-end engineer, I led our team in decoupling the Registry site from the company’s monolith, enabling engineers to iterate faster and to create a more stable experience for our users.
What I did
- Created a lightweight library for managing state using a pub/sub model with React Context.
- Emphasized stability and wrote tests to achieve extensive code coverage.
- Led team‘s efforts to improve front-end performance, creating dashboards to monitor web vitals, and reducing our first input delay to under 100ms.

- Improved form validation in the create-registry flow.

Favorites/Lists
2018 – 2020 You click the heart button to save items you like — which, not surprisingly, means it drives a disproportionate level of sales. Over two years, I worked on several major projects that improved the customer experience with favorites, both with the button and on the lists page.
What I did
- Implemented a complete redesign of the Lists landing page.
- Decoupled the save (aka “heart”) button into a stand-alone library and simplified the save flow for users with multiple lists
- Improved accessibility by enabling keyboard navigation and better support for screen readers.

What I did
- Led transition to responsive web design.
- Enabled 160 public radio stations to sunset costly mobile websites, reducing maintenance costs by 40%.
- Implemented BEM CSS methodology: Reduced visual regressions and decreased time to implement design changes by 25%.

2014 – 2015 Before NPR released a responsive news platform for member stations, we created a mobile-only news website.
What I did
- Designed a modified responsive website that was optimized for small screens.
- Wrote CSS, jQuery, and PHP for a custom Drupal theme.
- Trained team how to use CSS preprocessers and integrated Sass into our front end workflow.
