I'm a UK-based Designer.
what I can do
Skills I’ve used on real products, from PHS Shop and Harwoods to Ticketmaster’s Cities Page.
CRO Experimentation
Form hypotheses from research and analytics, then plan A/B and multivariate tests with clear success criteria.
Prioritise a test backlog using frameworks like PIE or ICE, so effort goes where impact is highest.
Build and QA variants in tools like VWO, then read the results and decide what to scale, iterate, or drop.
Report findings as clear narratives that link each test to conversion and revenue goals.
Behavioural Analysis & Insight
Analyse funnels and drop off in GA4 to find where and why people leave.
Use VWO heatmaps and session recordings to spot friction, missed clicks, and confusion.
Validate design decisions with preference tests, usability testing, interviews, and surveys, including Lyssna.
Turn qualitative and quantitative insight into prioritised recommendations that teams can act on.
Conversion Led UX & UI Design
Design and prototype landing pages, product pages, and checkout flows in Figma, from low to high fidelity.
Order page content so the most persuasive information lands where decisions are made.
Build and evolve design systems and reusable components that stay consistent and are ready for developers.
Design mobile first and for accessibility, so improvements work for everyone.

PHS Shop, Ecommerce Phase 1
Since launching in July, the shop has generated 600 orders and over £65k in net sales at a 53% gross margin, with an AOV of £112 against a target of £200.
Phase 1 of the PHS online shop, giving customers the choice to buy contractually or pay upfront for consumables. I joined in the later stage to validate and refine the designs from a UX and CRO perspective.
UI / UX Design
PHS Pre Built Component Designs
A new set of pre built, flexible website components designed in Figma for PHS’s CMS web builder, replacing reliance on hand coded elements. Each component is linked to a business goal and a CRO metric.
UX & CRO Design
Harwoods Homepage Redesign
I led the Harwoods homepage redesign end to end, using preference testing via Lyssna to validate hierarchy and trust decisions before running live A/B experiments to test them with real customers.
Redesigned a premium automotive homepage using data led insights and user testing to improve hierarchy, trust, and engagement for high intent users.
UI / UX Design
Insight-led City Destination Page MVP
I owned the discovery strategy for the Cities Page, deciding which signals mattered most for surfacing relevant events and shaping the page hierarchy around that, before handing off a design ready for build across 200 plus markets.
Led the research and early ideation behind Ticketmaster’s new city-based discovery experience, making event exploration more intuitive and engaging for fans.
UI / UX Design
B2B Internal CMS Scheduler
I decided how scheduling permissions and page states should work for the CMS, simplifying a technical publishing process into a flow that 100 plus stakeholders could use without needing engineering support.
Designed an internal CMS feature that lets stakeholders easily schedule and manage pages, boosting operational efficiency across global teams.
UI / UX Design
Music Social Networking App
Designed 50+ mobile screens and a component library for a product that enables emerging artists to present themselves more professionally to connect with other creatives and industry professionals.
Designed a mobile app that helps emerging artists connect, collaborate, and present themselves professionally in the music industry.
im more than just a UX/CRO Designer…
I also create motion illustrations, digital artwork, graphic design and hand-drawn pieces, blending craft and creativity across every medium I touch.

Stefan embedded himself quickly with professionalism and curiosity. He took full ownership of a core internal tool, delivering user-centred solutions with real accountability and initiative. I highly recommend him.
