I leave the web better than I found it.

Ethical software engineering, founded on the principles of accessibility and sustainability.

the gist

As a seasoned software engineer with over 8 years of experience shipping web applications across a range of industries, I am passionate about improving the Internet and its impact by building performant and accessible web applications.

I specialize in frontend development, using technologies such as JavaScript and TypeScript, Next.js, and semantic HTML, and I have a keen eye for design and user experience. I excel at cross-functional collaboration, transforming ambiguity into clarity, and creating state-of-the-art, sustainable systems for my teammates and users.

Hiring Annie as a frontend engineering contractor at Voura was one of the best team decisions I’ve made in my career.

She quickly shipped customer-facing UI while elevating the quality of our codebase and building a design system all at the same time. After only a few months, we had reusable components that allowed us to easily add new functionality and user experiences at the drop of a hat.

Outside of her technical skills and speed of development, Annie is an amazing collaborator and communicator. I would recommend for anyone needing frontend engineering help to hire Annie. Your project will get done at a very high level and your engineering culture will more likely than not change for the better!

She helped to carve clarity out of ambiguity and ensure that we not only delivered on time, but with the highest quality possible.

Annie is by far the best front end developer I’ve ever had the pleasure of working with. She brings a high quality of excellence to everything she does. She is always thinking about the end user and how to ensure that the front end scales. She thinks both systematically as well as holistically. Annie has a keen eye for design and there were times where I couldn’t tell the difference between my Figma files and production.

She challenged and grew my understanding of accessible and sustainable design. Her comments during reviews were so thorough and thoughtful - I can’t say enough. Annie truly levels up anything she works on.
