Cover image for Bulky card holders and cash
Bulky card holders and cash often get in the way on the training fields. Merging active sports with modern digital assets usually means fighting confusing blockchain setups. Golfer Wallet solves this by connecting decentralized finance directly with the game. • Live balances: the platform displays alternative crypto coins alongside real-time market values. • Asset galleries: digital art collections stay organized inside a clean visual showcase. • Code scanning: built-in tools read merchant graphics for rapid on-site transfers. • Direct mapping: integrated navigation pinpoints crypto-friendly country clubs and participating courses instantly. Sports venues attract younger audiences while players unlock concrete discounts during training. Personal asset auditing remains simple, allowing fans to enjoy modern checkout methods right on the green.

The Blockchain Virus: How It Detects and Heals Itself 🦠 Imagine if every piece of data could protect itself — like a digital virus that spreads, checks its copies, and deletes any infection automatically. That’s exactly how blockchain works. In this video, you’ll see how each block copies itself across thousands of computers, how the network detects an attack, and how consensus heals the chain without a single human involved.

Imagine chain.link (https://chain.link) oracles as librarians fetching verified data for smart contracts. Now imagine instead of humans, you have five super-intelligent, independent AI librarians arguing over every detail — counting followers, checking engagement, judging authenticity — and only agreeing when the facts match. That’s decentralized AI oracles. No single API can be blocked. No human bias can slip in. Contracts finally understand nuance: “Pay if engagement is real, not bots.” It’s like replacing the courtroom with a jury of machines that never sleep, never lie, and actually read everything.

What if proving who you are didn’t depend on governments, banks, or companies — but on math and your own device? That’s blockchain attestation. It’s a way to prove you’re real, unique, and trustworthy without showing your face or asking permission. Your device, cryptography, and a public blockchain work together to create an identity no one can delete, block, or fake. Think secure voting, censorship-proof access, and digital freedom — all in one system. Attestation on-chain isn’t just tech — it’s the future of identity, trust, and democracy.

Developed an NFT marketplace for AB InBev's beverage brand to help them engage loyal customers through blockchain technology and digital collectibles. I also implemented the provided branding and design with a strong focus on performance, responsiveness and user experience, delivering the platform on a fast timeline. The marketplace enabled users to explore, purchase and manage beverage-themed NFTs while aligning with the client's vision of expanding into the Web3 ecosystem.

Cover image for InstallPay: Buy Now, Pay Later
InstallPay: Buy Now, Pay Later App UI Kit InstallPay is a BNPL app UI kit I designed and released as a standalone product. It covers 50+ screens and 80+ components across onboarding, shopping, card management, orders, payments, notifications, and account settings, all sitting on one design system so a team can ship a working fintech product without starting from zero. Every screen is built around real BNPL behaviour: splitting a purchase into four interest-free payments, tracking total owed against what's due in 30 and 60 days, adding and switching between credit and debit cards, browsing brands, and setting a 4-digit PIN for quick login. Components use variables and auto layout, so colour, type, and spacing update across the whole file in a single pass instead of screen by screen. I made this because most fintech kits stop at pretty screens and fall apart the moment you need a real payment schedule or a card state that isn't the happy path. This one is meant to be picked up and built on. It's available on Figma Community and Lemon Squeezy. #UIDesign #UXDesign #MobileAppDesign #DesignSystems #Figma #Fintech #ProductDesign
