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.

Helping tech companies grow through design
Cover image for Developed an NFT marketplace for
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 Streak wanted a platform where
Streak wanted a platform where fans could connect with local sports players, follow athletes they already care about, and discover new talent early. Fans could also buy NFTs tied to the athletes they support, so backing someone actually meant something. I started by studying the client's existing app and mapping out product requirements before designing anything. From there came research, analysis, and low fidelity wireframes shared with the client to make sure we were aligned. Once that was locked, I moved into high fidelity concepts with prototyping, navigation, and micro interactions. The visual direction is dark and moody with fluorescent accents, built on Graphik with a black and white base palette so the athlete photography carries all the energy. I designed the marketing website and the mobile app together, covering athlete profiles, fan community feeds, live streaming, and exclusive access to collectibles. #ProductDesign #UIUX #Web3 #NFT #MobileAppDesign #WebDesign #SportsTech #DarkUI

Cover image for Dunmor is a real
Dunmor is a real estate lending platform serving investors who need financing fast. They came to us for a website design that could carry the brand and convert at the same time. The core problem was product complexity. Dunmor offers four lending products, fix and flip, bridge, construction, and rentals, and each one speaks to a different borrower with different questions. The old site treated them as a flat list. We rebuilt the site around modules so every product gets its own entry point, its own numbers, loan size, leverage, interest rate, and its own path to a quote. We ran interviews, competitor analysis, and research first, then used a moodboard to lock the visual direction with the client early. That saved rounds later. From there it was wireframing, prototyping, and visual design on top of a defined design system. The direction leans dark, electric blue and lime against deep navy. It reads like a fintech product rather than a mortgage broker, which was the point. Real photography keeps it grounded so the tech feel never gets cold. Mobile mattered more than usual. Dunmor's clients are contractors and investors checking loan terms between site visits, so every page works as a vertical scroll with full loan detail available, no desktop login needed. We delivered the website design, the responsive mobile experience, a reusable module library, and a design system the client's team can build on. #WebsiteDesign #UIUXDesign #ResponsiveWebDesign #Fintech #RealEstateTech

Cover image for VMGNT — Talent Management is
VMGNT — Talent Management is a UK talent agency representing models who work with names like Elle, Longchamp and Chloé, and until this project they had no real digital home. Everything lived on Instagram. They wanted a site that could carry that level of talent without competing with it, which is a harder brief than it sounds, because the work is photography and video and the design has to get out of its way. I went with a stark black and white palette and pushed the interface to the edges so imagery fills the screen, with the logo held quietly in the corner. The talent grid lets visitors browse by city and category, and each model gets a full profile with lookbooks, editorial work and social reach. Adding model lookbooks was the change that shifted the site from a directory into something people actually stay on. I designed it responsive from the start, since most people find talent on a phone, and ran contrast research through the colour work so the type stays legible against full bleed photography for anyone with a visual impairment.
