Open to remote & Denver hybrid

UI / UX / CRO — in one seat.

Frontend, Funnel Optimization, Product owner

I analyze data and run experiments to raise conversion. I ship the interface and its iterations, plus the events it fires. JS, CSS, and SCSS from spec to coherent code. Membership and webinar flows, UTM handoff, GTM dataLayer, and continuous optimization. I can own a frontend without a large team or work with one. Seeking a senior product role.

Interfaces in production

Why this seat

Production interfaces in React and Next.js, the events those pages fire, and a Sass codebase that stays coherent with the design spec.

01
React and Next.js
I build the interfaces that ship. JavaScript, CSS, and SCSS sit under that work.
02
Design to Sass
Matching a design spec and keeping a Sass codebase coherent is normal work, not a special project.
03
Own the frontend
Membership and funnel flows, UTM logic, the test, the events, and the hypothesis. The conversion readout stayed with the company.

What I bring to the seat

CRO
Consider multiple data-streams and create experiments for optimization and improvement. From hypothesis, to iteration, the measurement, and the conversion.
Design to production
On or off-brand implementation, ensuring that the final product aligns with the brand's identity or requirements.
React and Next.js
AI assisted production. Components, pages, and the release that follows a spec.
JavaScript, CSS, and SCSS
JavaScript, CSS, and SCSS, including a Sass codebase that stays coherent as it grows.

Experience snapshot

2021 – 2026
CRO & UI/UX Specialist
Simpler Trading

Owned the page, the redirect and UTM handoff, and the GTM dataLayer events for membership and webinar registration. Shipped on a weekly release. The conversion readout stayed with the company.

2017 – 2021
Lead UI/UX Designer
Leading Response

Led design and development for marketing products. Built the analytics and testing frameworks the campaigns ran on.

A release week

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

01
Design 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
Testing
The path is exercised before it ships: the redirect, the parameters, the event, and the layout on a phone.
06
Ship it
It goes out in the weekly release. The next offer reuses the page, the events, and the Sass.
