Product design for money, markets & moves.
I'm Malvin Yeung — a San Francisco Bay Area product designer with 12 years shipping consumer fintech, crypto, and Web3. Previously at Apple and Salesforce, recently designing earn, trading, wallet, and discovery experiences at OKX, Magic Eden, Slingshot, and Flex.
Four flagship case studies. Receipts attached.
OKX Earn
Reimagined OKX's Earn surface — the unified home for staking, savings, structured products, and on-chain yield across 100+ assets. Simplified a product catalogue that had grown organically into a single discovery layer, then rebuilt the subscribe / redeem flows to make risk, APY, and lock-up terms legible in one glance.
Magic Eden Mobile 2.0
Reimagined the Magic Eden mobile experience from a feed-first browse tool into a multi-chain trading and discovery app. Owned the end-to-end IA, wallet onboarding, and the new discovery surface used by collectors on iOS and Android.
Slingshot App
I was the only designer on Slingshot — owning the product end-to-end from first concept through App Store launch and every release after it. That meant the consumer-grade swap experience across 8+ chains, collapsing routing, slippage, and gas decisions into a single confident tap; the brand system and motion language that became Slingshot's identity in app stores; and the design system that kept quality consistent as the app shipped continuously through acquisition by Magic Eden.
Apple Product Requirements App
The product-requirements workflow at Apple was fragmented across email, Quip, and half-a-dozen other tools — no single source of truth, no version control, no formal approvals. I led design end-to-end for a purpose-built app that gave business owners a place to author requirements, gave engineers a reliable feed to build against, and closed the loop with a first-class approval and action-item system. Shipped MVP in four months and rolled out 15+ enhancements after launch.
Ten more shipped products.
NFT Perp Exchange
'23Designed the first leveraged NFT perpetuals interface — bringing order-book trading to floor-price assets.
Chainlink Explorer
'19An on-chain oracle explorer that made data feeds legible to non-engineers across the Chainlink ecosystem.
Flex App
'22Perps trading experience for Slingshot Flex — order ticket, risk overlay, and leverage flows for on-chain traders.
DeFi Dashboards
'21yAxis, PrePO, SkopeAI, LinkSwap — dashboard systems for staking, derivatives, AI portfolios, and DEX swaps.
Slingshot Wallet v1
'22Sole designer on the original Slingshot non-custodial wallet — the foundation that scaled into the mobile app.
Salesforce.com
'16Pricing, guided tours, navigation, and "How to Buy" — marketing surfaces for the world's biggest CRM.
Facebook Help Intake
'19A case-routing intake flow used by Facebook employee HR support — deflecting cases and cutting triage steps.
GDPR Design System
'18Componentized consent & privacy surfaces for a multi-product GDPR rollout — one system, many products.
Options Trader App
'19Concept exploration for a retail options interface that makes order entry faster than Thinkorswim — fewer taps to a trade.
Cryptocurrency Exchange
'19End-to-end design for a mobile-first retail crypto exchange & wallet — onboarding, market, trading, and transfers.

Designing financial products where trust is non-negotiable.
I design financial products that make complexity feel effortless and earn trust when the stakes are high.
I'm an AI-native product designer with 12 years of experience designing and shipping end-to-end products for global companies and high-growth startups. I specialize in fintech, crypto, Web3, and DeFi — translating complex systems across payments, trading, wallets, and liquidity into intuitive, scalable experiences people can confidently use.
My foundation at Apple and Salesforce shaped how I approach design: start with the customer, bring clarity to ambiguity, think in systems, and obsess over the details that separate a functional product from an exceptional one.
I work across the full product lifecycle — research, product strategy, user flows, prototyping, interaction design, visual design, experimentation, design systems, and engineering handoff. I'm equally comfortable defining the right product direction and refining the motion, content, and interaction details that make an experience feel premium, fast, and trustworthy.
Currently, I design global payments, trading, and Earn experiences at OKX for millions of users. Previously, I worked on trading, discovery, and wallet products at Slingshot and Magic Eden. Across every role, I've partnered closely with product, engineering, research, data, and business leaders to connect customer needs with business goals and technical realities.
AI is embedded in how I work. I use Claude, ChatGPT, Figma Make, and rapid prototyping to synthesize insights, explore product directions, test assumptions, and move from idea to evidence faster. AI accelerates the process, but strong judgment, customer understanding, and design craft determine the outcome.
What sets me apart is range. I can zoom out to shape product strategy and complex systems, then zoom in to perfect the experience at the interaction level.
I'm at my best helping ambitious teams launch new financial products, simplify complicated workflows, and scale their experiences without sacrificing quality.
What collaborators say.
Malvin is a UX workhorse — creative, professional, and whip smart. During my time at Salesforce, managing Malvin has been a real treat. A few of the facets that make him a stellar designer:
- He really understands the business impact of design and is able to manage complex sets of design deliverables across a project lifecycle and multiple releases.
- Independently and collaboratively problem solves with cross-functional team members.
Jacob Swift
UX Architect · Managed Malvin at Salesforce · 2018
Malvin was part of a consulting team at General Assembly to propose a UI design for my company's iPhone and Apple Watch UI. He got the team into action by reaching into his network and having users ready for UI research — before I even met with the team! Malvin is technical and a good communicator — a reliable, go-getter, substantive addition to any team that gets to work with him.

Malvin provided me helpful insights on how to make an internet-of-things product more closely tied to social media in order to promote awareness and more frequent use of the product.

Have a hard product
problem? Let's talk.
Whether you're hiring a senior designer, need a contract partner to ship a release, or want a second pair of eyes on a flow that isn't converting — I'd like to hear about it. Fintech and crypto are home turf, but the real specialty is making complicated things feel simple. Send a note, a Figma link, or a wild idea.
