Hi, I'm Katie
I'm a creative front-end engineer.
Front-End Development
I build fast, accessible websites and web apps with React, TypeScript, and Next.js, so your site feels smooth for visitors and is easy to grow over time.
Services
Design-to-Code Implementation
Already have designs in Figma? I turn them into pixel-accurate, responsive interfaces that look right on every screen and match what your designer intended.
Redesigns & Performance Improvements
If your current site is slow, outdated, or hard to use on mobile, I’ll modernize it, improving load times, accessibility, and usability so visitors stay and take action.
Front-End Support for Teams
Need an extra senior engineer? I can join your team for feature work, code reviews, documentation, or TypeScript migrations, with the experience of having led front-end work at a growing company.
Design Systems & Component Libraries
I create reusable component libraries with Storybook, so your team builds new pages faster and your brand stays consistent as you grow.
Web Apps & Dashboards
From customer portals to data dashboards, I build interactive tools that make complex information clear and easy to use. I can also connect them to your APIs and handle light back-end work when needed.

About
My mission is to bring ideas to life through fast, polished web applications that work beautifully on every device.
I’m a freelance front-end engineer with over seven years of experience, including time as a Staff Engineer leading front-end work for a growing product team. I also have hands-on experience with design and back end development, so I can help carry your project from first idea to launch. I’ll explain things in plain language, keep you in the loop, and build something you can feel confident about.
I gravitated towards front-end development after realizing its perfect union of problem solving and visual creativity. Nothing beats the satisfaction when a tricky problem clicks, or the moment you see an idea come to life on screen.
Away from the keyboard, you’ll find me running, baking, reading, or traveling to all corners of the world.
Have an idea? I’d love to hear about it.
