Convert, Optimizely, Adobe Target, Dynamic Yield, Monetate, VWO, and Intelligems for Shopify. I build experiments that hold up to engineering review, accessibility audits, and SPA edge cases — for retailers, builders' merchants, insurers, and DTC brands.
Available for direct work and as overflow dev capacity for CRO agencies. Active partnerships with Brainlabs, FunnelEnvy, Browsertobuyer, and MoreConversion.
Selected experiments showing the kinds of problems I solve — SPA-aware UI, server-load mitigation, enterprise platform quirks, and accessibility-compliant variants.
Large UK home improvement retailer
Vertical search overlay had low engagement. F-pattern reading suggested a landscape layout could lift SRP progression.
Built a darkened focus-state overlay, repositioned the search element to a landscape layout, and added search-term-driven subcategory chips for Variant 2. Maintained existing product-suggestion logic to isolate layout as the variable. Two variants shipped sitewide on desktop.

Google Shopping landers were exiting PDPs and re-entering through Shopping multiple times when the specific product didn't fit. Top-50 power-tool SKUs by click volume were the priority.
Built a sticky "follow-me" similar-products carousel
scoped to the product's category. Scrapes the breadcrumb-derived PLP at a
price-bound API call, caches results in sessionStorage so
subsequent PDPs in the same category render instantly. V2 layers a brand
filter for brand-loyal users.
UK builders' merchant
Trade prices were rendered separately from retail prices on PLPs and PDPs, so non-account users couldn't easily compare the two and weren't motivated to create a trade account. The hypothesis: making trade prices visually dominant alongside retail prices would lift trade account creation.
Replaced the host's separate trade-price block with a unified price banner showing retail and trade side-by-side, gated to logged-out users via cookie check. Banner click opens an embedded login modal using the host's own identity SDK, with a separate "I don't have an account" CTA routing to signup.

Internal data showed bundled "Gas Combo" products had lower year-on-year renewal rates than single-category cover, dragging long-term profitability. Stakeholders wanted to surface them on a separate page so single-category products got cleaner focus.
Removed bundle items from three comparison PLPs by URL match, restructured the grid from 3-up to 2-up, destroyed and re-initialised the Swiper instance to match the new slide count, and dynamically injected a new nav link to the dedicated bundle page once a user had visited a comparison PLP.

Off-boarding from the UK site cut the planned social-proof test runtime short. The team needed a market that could deliver significance inside a tight timeframe.
Built a 19-product bestsellers carousel with desktop
dropdown and mobile bottom-sheet variant pickers, integrated with Avon's
internal product API and CartServiceModule for inline add-to-bag,
plus IntersectionObserver-driven impression tracking on both control and
variant.
UK luxury flooring retailer (Magento)
Customer gallery sat on a separate page where most homepage visitors never reached it — a high-trust social proof asset locked behind a navigation step.
Live-fetched the customer gallery into the homepage, built a product modal that scrapes form data from PDPs to power inline AJAX sample ordering, and surfaced Magento's native success/error notifications by cloning the host's existing UI.

Plain PLP exit rate of 14.4% across organic and paid channels — users were leaving without finding a product that matched their price or criteria. Returning users exited at 15.1%.
Built a custom ExitIntent detection class
(mouse trajectory, inactivity, tab-switch heuristics), an accessible modal
with focus trap, and a V2 carousel that fetches category-relevant clearance
products at price ranges derived from the breadcrumb and SKU scrape.
