About Me

I've led feature development on Apple device management tools, migrated codebases from Backbone to Vue Router and Redux to Pinia, and improved user experience with clean, accessible interfaces backed by thoughtful state architecture.

I care deeply about developer ergonomics, code maintainability, and fast, intuitive user flows.

Clean UI, Honest UX

I believe interfaces should behave as expected. No scrolljacking! I build features that respect user habits and developer sanity.

Get It Done

I value direct collaboration, thoughtful naming, and making sure future developers don't hate me.

Past Builds: They've Moved On, But I Was There:

Crown Royal Whisky - wrote some CSS for the main slider.

Energizer Batteries - rebuilt the Power and Lighting menus, adhering to both desktop and mobile PSDs sent to me by the design team.

VO5 Haircare, Zest, Coast soap, White Rain- most content entry/packaging images. Integrated Press Room page on VO5.

Olympus Camera promotion - Mostly built by me; built and styled the templates, and integrated the forms.

Point72 - most static template builds (minus Wistia video integration), most styles. This was a huge, months-long build, using multiple branches concurrently, with testing and deployment responsibility resting on me.

Amherst Insight Labs, Amherst Holdings - built all templates and most styles.

Barhunter app - built HTML and CSS. This was a static prototype for a mobile-only app for looking up either bars or liquor stores (depending on which option was chosen by the end user) in Mexico City. Has not been deployed yet, but here are screenshots from spinning up a server from my local copy:
