Senior product seat · Lakewood, CO

I build production interfaces in React and Next.js.

Front-end Engineer · React, Next.js & CRO

Twenty years in JavaScript, CSS, and SCSS. Matching a Figma spec and keeping a Sass codebase coherent is normal work. I have shipped the CRO on the pages people convert on—membership and webinar flows, redirect and UTM logic, GTM dataLayer events—and I can own a frontend without a large team around me. I am looking for a senior product seat.

Interfaces in production

Membership pricing, an offer table, and a sales page. These are CRO surfaces people convert on.

Why this seat

Production interfaces in React and Next.js, CRO on the pages people convert on, and a Sass codebase that stays coherent with the Figma spec.

01
React and Next.js
I build the interfaces that ship. Twenty years in JavaScript, CSS, and SCSS sit under that work.
02
Figma to Sass
Matching a Figma spec and keeping a Sass codebase coherent is normal work, not a special project.
03
Own the frontend
CRO for membership and webinar flows, redirect and UTM logic, and GTM dataLayer events. Tests and weekly releases, without a large team around the work.

What I bring to the seat

React and Next.js
Production interfaces. Components, pages, and the release that follows a spec.
JavaScript, CSS, and SCSS
Twenty years in the languages the interface is made of, including a Sass codebase that stays coherent as it grows.
Figma to production
A Figma spec comes in. The Sass, the components, and the page that ships still match it.
CRO
The pages people convert on: membership and webinar flows, redirect and UTM logic, and GTM dataLayer events, with the same care as tests and a weekly release.

A release week

Spec, Sass, the page, the events, the test, and the ship. This is what owning the frontend looks like.

01
Figma spec
The frame arrives with type, space, and the states the page needs. Matching it is how the week starts.
02
Sass
Tokens and components stay coherent with that spec. The new page uses the system that is already in the codebase.
03
The page
A membership offer, a webinar registration, or a pricing UI lands as a real page, with the layout and the JavaScript that make the decision obvious.
04
The events
GTM dataLayer events record the view and the signup. UTM values are still on those events after a redirect.
05
The test
The path is exercised before it ships: the redirect, the parameters, the event, and the layout on a phone.
06
The ship
It goes out in the weekly release. The next offer reuses the page, the events, and the Sass.
