Profile Summary
- Senior UX/UI Designer with 7 years of experience shipping consumer mobile and web products at marketplace scale across on-demand delivery, marketplaces, and consumer mobile, specializing in end-to-end product design, tokenized design systems, and WCAG 2.2 AA accessibility.
- Hands-on coverage across design (Figma with FigJam), prototyping (Figma with Smart Animate), research (Maze with Dovetail), design systems (tokenized Figma libraries with auto-layout), and accessibility (WCAG 2.2 AA across web and mobile), credentialed through Interaction Design Foundation certifications.
- Deep craft in discovery research with synthesis into product strategy, information architecture and user flows for content-heavy products, visual and interaction design with motion and micro-interactions, and usability testing and iteration on every release, applying methods such as weekly design critiques with engineering and product partners and design system contributions reviewed by the platform design team to deliver accessible, on-brand product experiences that move task success and conversion.
- Engaged collaborator working cross-functionally with Product, Engineering, Research, Content, and Brand teams inside dual-track agile product squads, contributing to weekly critiques, portfolio reviews, and roadmap shaping with an ownership-first mindset and clean handoffs in Figma Dev Mode.
- Mentor who shares technical excellence and fosters a culture of accessible, well-tokenized interfaces and research-grounded, evidence-led product decisions through critique facilitation and rationale docs, while running the internal design system guild and accessibility working group and authoring widely used component patterns and audit playbooks.

Work Experience
Glovo
Senior UX/UI
Designer
- Led discovery research on the consumer ordering app and courier ops console serving 18M monthly active users, running moderated interviews, contextual ride-alongs with couriers, and unmoderated tests in Maze, synthesizing 64 interviews in Dovetail into journey maps and running 28 studies a year that fed the quarterly product strategy.
- Owned information architecture and user flows, where I restructured navigation around verticals (food, groceries, pharmacy) with cross-vertical search and saved-place shortcuts, ran card-sorting and tree testing in Optimal Workshop across 84 screens, and cut steps-to-checkout by 38% on the consumer side.
- Drove wireframing and prototyping with low-fi wireframes in FigJam, hi-fi Figma flows with Smart Animate, and clickable prototypes routed through Maze, shipping 46 production prototypes a year and running 3 to 5 tested iterations per concept before dev handoff in Figma Dev Mode.
- Shaped visual and interaction design across consumer surfaces, where I reworked type ramp, spacing scale, and iconography in the Glovo brand system, with motion guidelines for transitions and feedback, shipped 120 releases across the year, and lifted add-to-cart conversion by 14% on the redesigned home feed.
- Owned design systems and component libraries grounded in tokenized Figma libraries with auto-layout, Figma variables for theming, and Storybook handoff for engineers, governed 58 shared components through a contribution model with 22 active engineering and design contributors, and lifted design-to-ship velocity by 2.4x.
- Ran usability testing and iteration through weekly unmoderated Maze tests on hot flows, moderated UserTesting sessions on net-new features, and A/B tests with PMs on every release, shipping 32 studies per quarter, lifting task success rate by 22% on the checkout flow, and pulling A/B winners at a median 9% conversion delta.
- Drove accessibility and inclusive design through WCAG 2.2 AA audits across web and mobile, contrast and focus tokens in the design system, and screen reader runs in VoiceOver and TalkBack, auditing 210 screens against WCAG 2.2 AA, clearing them at a 98% pass rate against EN 301 549, and re-running every fix with VoiceOver, TalkBack, NVDA before sign-off.
Typeform
UX/UI
Designer
- Worked cross-functionally with PMs and front-end engineers from kickoff through design QA, with Research and Content in the room from day one, embedded across 3 product squads, and shipped 22 end-to-end launches under a dual-track agile cadence with weekly design and dev syncs.
- Led design critique and communication, where I ran weekly design critiques, presented work to PMs and stakeholders, and wrote design rationale docs in Notion for every shipped flow, facilitating 90+ critique sessions over the role and turning trade-offs into 12 shared design principles that the whole team referenced on roadmap planning.
- Connected design to product strategy, where I tied design work to activation, completion, and retention OKRs, and co-authored the form-builder vision with the Head of Design, lifting form-completion rate by 19% on the redesigned canvas and feeding the next-quarter roadmap with research-backed bets.
- Owned design end to end on the form-builder canvas, where I owned the form-builder canvas end to end: research, IA, wireframes, high-fidelity Figma, prototypes in Principle, and dev QA at launch, shipping 14 net-new canvas features under a single design owner partnered with a senior designer mentor with consistent visual and interaction patterns across the surface.
