01

A founding role, from product decisions to production

Since December 2025, I've worked full-time as Axel's Founding Design Engineer, reporting directly to the CEO. I take product problems from early exploration through interface design, frontend implementation, testing and engineering review. My remit also covers the brand and the creative work that brings people into the product.

  • Product design

    User journeys, interaction design and the details of booking and membership experiences.

  • Frontend engineering

    Production React, reusable components, responsive layouts, interaction states and motion—delivered as PRs.

  • Brand & campaigns

    Visual identity, core advertising campaign creative and the landing pages that connect them to the product.

  • Email & testing

    Transactional email design and implementation, product QA and iterative testing.

02

Building through 0 → 30M GMV

Axel grew from 0 to 30M GMV and 0 to 100K+ users. My contribution spans the experience people discover, the product they use and the communications they receive: product design, frontend PRs, brand, campaigns and email. I work with the team to turn growth priorities into changes we can ship, test and refine.

03

I ship pull requests

My primary deliverable is a reviewable PR. I work in the frontend codebase, building the components, layouts, states and interactions needed to carry an experience into production. On helloaxel.com, that includes the landing experience, conversational interface and motion. A working preview lets the team review the actual behavior alongside the code.

The collaboration runs both ways

I connect design and engineering in both directions. Design → engineering: I turn intent into components, interaction states and PRs that engineers can review. Engineering → design: I bring implementation feedback, real data and technical constraints back into the experience. Working with the lead engineer, I help keep the design and the running product aligned as both evolve.

05

Fast iteration with AI coding tools

I use AI coding tools throughout prototyping and implementation to move quickly from a design decision to a working change. The shared workflow with engineering gives that speed structure: focused PRs, clear review context and checks appropriate to the change. I stay responsible for the experience, the code I submit and the testing behind it.

  • Build quickly

    Use AI to explore interactions, implement frontend changes and iterate in the product's existing stack.

  • Make review concrete

    Pair the code diff with a preview and the user scenarios the change affects.

  • Match review to impact

    Work with engineering on behavior, data and sensitive flows; verify visual and interaction details throughout.

Chapter 03Brand & growth

06

One experience, from the ad to the product

I work across branding, visual identity and core advertising campaigns, carrying the same visual direction into landing pages and the product. That scope connects acquisition creative to what a traveler sees next. Within the product, my work includes booking and membership experiences, with attention to how people understand membership value and savings.

“I connect the brand people discover with the product they actually use.”

07

Email is part of the product

I design and maintain 28 transactional email templates in Customer.io and Liquid, from onboarding to cancellation. The work combines visual design with implementation: using real event data, handling missing values and checking how messages render. Email carries the same care as the interface because it is often where people learn what happened and what to do next.
