Drove end-to-end e-commerce UX through hyper-growth and a successful acquisition.

Leading cross-functional design and front-end operations, I treated the storefront as an instrument to be measured and tuned — instrumenting the purchase flow, removing friction, and holding engineering to a performance standard rather than a ticket count.

  • 01Lifted conversion 20.65% on mobile and 20.41% on desktop with a redesigned checkout navigation.
  • 02Raised mobile conversion a further 16% by moving the coupon field to the payment step to cut friction.
  • 03Rebuilt the header and integrated tire finder, and cut mobile page load from 9.1 to 8.3 seconds by stripping bloated header and image code.
  • 04Established a UX research practice using usability testing and session analytics to reduce cognitive load in the purchase flow.
  • 05Authored and presented an accessibility remediation proposal to leadership in response to litigation, reducing legal and financial exposure.
01 Situation
By early 2018, the customer experience was no longer meeting business objectives.

Revenue from mobile traffic and average order value had stagnated, while product landing pages suffered from excessive load times. The offshore engineering team was measured on ticket volume rather than code quality, accumulating technical debt that put both conversion and organic search rankings at risk.

Following these declines, the CMO requested a strategic intervention to rebuild the customer experience and recover lost performance.

Symptom A
Stalled growth

Mobile revenue and average order value flat despite steady traffic.

Symptom B
Heavy pages

Bloated header and image code dragging product landing page load times.

Symptom C
Quantity over quality

Offshore team optimizing for ticket count, compounding tech debt and SEO risk.

02 Task
Find the root causes — then lead a cross-functional recovery.

As UX Lead, my objective was to modernize the mobile experience, raise front-end engineering quality, and optimize technical performance to drive measurable revenue growth and SEO health. The mandate spanned three teams that didn't routinely work together: design, marketing, and offshore engineering.

I partnered with the Director of Marketing and the CTO to execute a multi-phase turnaround built on three pillars.

03 Action
A three-pillar turnaround: diagnose, redesign, optimize.
A

Discovery & diagnostics

Before touching the UI, I built a shared, evidence-based picture of where the experience was breaking down.

Behavioral
Heatmaps & recordings

HotJar session recordings and heatmaps to locate friction in the purchase flow.

Technical
Lighthouse audits

Surfaced unoptimized images, legacy HTML, and cluttered DOM structures.

Alignment
Voice-of-customer

Cross-referenced performance data with support feedback to validate navigation pain points.

B

Mobile-first redesign

I led a data-driven UI cleanup of the navigation and product detail pages, simplifying call-to-action visibility based on heatmapping insights. The header was rebuilt around an integrated tire finder so shoppers could start a search — by vehicle or by tire size — from anywhere on the site.

C

Checkout redesign & engineering quality gate

The revised mobile checkout (ticket SIM-4384) reorganized the flow into clear, single-purpose steps: choose a shipping method and local installer, schedule the install, pay, and confirm. I also collaborated with the CTO to overhaul offshore engineering metrics — shifting from ticket volume to performance impact, with a mandatory UX quality review on every critical-path journey.

The coupon-field insightSession data showed shoppers leaving the flow to hunt for a code. Moving the coupon field to the payment step removed that detour and lifted mobile conversion a further 16% — a small relocation with an outsized result.
D

Technical optimization

I directed the removal of legacy code and established a formal image-optimization protocol to reduce page weight and DOM size. Stripping bloated header and image code cut mobile load from 9.1 to 8.3 seconds on the header alone, with the broader page-weight work driving the site-wide gains documented in the results — and lifting SEO health through improved DOM efficiency.
