Deep Focus is a fictional macOS app that silences notifications so people can do deep work. The catch is the audience: people who need a productivity app are already tired of apps. Every competitor promises more features, so this page had to promise relief and turn it into a download within seconds.
What I did
I started from the pain, not the product. The second screen lists what a normal day looks like: push notifications, endless pings, 142 unread emails, context switching. I styled those chips like the four benefit chips in the hero, only white instead of frosted, so the visitor reads before and after without a line of explanation.
The hero section design shows no interface on purpose. This product is about absence, and a screenshot would add noise, so a person alone in a field does the proving. The headline “Deep focus. Anywhere.” is a high-contrast serif because every tool in this category speaks in a grotesque, and a serif sounds calm and human.
I kept one action, Download for macOS, with no pricing and no form. The first job of this landing page design is a download, and everything else can wait until after it.
Would you keep the serif for the headline, or switch to a grotesque so it feels more like software?

What if sending money felt a little more like giving a gift?
For Nova, I explored a banking app that brings payments, cards, and a bit of personality together. You can check your balance, browse recent transactions, send or request money, top up, and pay bills.
My favorite part is the digital postcard feature. Before sending a transfer, you can add a little illustrated card—a heart, a birthday greeting, or a playful character. A simple way to make birthday money or a thank-you feel more personal.
I carried that same 3D character into onboarding, pairing it with bold red gradients and large, clear payment details. There’s room for play, while the recipient and amount stay easy to check.
Would you add a postcard to a transfer? I’d love to know what occasion you’d use it for.

Casemate: making malware analysis feel calm instead of scary
Cybersecurity websites usually look the same: black background, green code, a hooded guy. I wanted to try the opposite for Casemate, a concept for a malware analysis tool.
The idea is simple: the product keeps a suspicious file in a sealed chamber and watches what it does. So I put a bug frozen in amber in the middle of a canyon. It’s dangerous and under control at the same time, and you get it without reading a word.
Then I made sure the page still works for a security lead who wants facts. The stats sit right next to the headline: threats isolated, latency, endpoints covered.
The hardest part was keeping it warm without losing trust. I stayed with one terracotta colour, wide capitals and mono labels, so it reads like a serious tool and not a poster.
I’m taking on new projects for SaaS and tech teams. If you have a product that’s hard to explain in one glance, send me a message.
What do you think, would you trust a security product with a canyon on the homepage?

Alibi: Know before you ship.
Every designer knows this moment: two versions on the screen, a deadline, and a team that can't agree. Usually the loudest opinion wins. I wanted a place where you can just ask people instead.
So I built Alibi, a social network for quick design studies. You post a question, people answer in a couple of taps, and in a few hours/days you get a clear verdict. Not feedback from a client who has seen your file twenty times :) but a fresh take from people who see it for the first time.
What you can test:
• Compare: which of 2-4 versions works better
• First click: where people click first, shown as a heatmap
• First impression: your design is shown for 5 seconds, then one question
• Feedback: a quick 1-5 score
Across product design, graphic design, copy, motion and product ideas.
Why I'd scroll it myself
I spend way too much time scrolling Threads anyway. With Alibi that time actually turns into something: I see how other designers think, I get ideas, and my two taps help someone ship a better version.
Automation - what happens on its own:
• You set a secret success rule that only you see, like "A wins with at least 60%"
• The study closes itself at its answer target or deadline and counts everything automatically: shares, heatmaps, averages
• You get a verdict, Confirmed or Not confirmed, and everyone who answered gets notified
• Ran out of time? Extend by 7 days, keep it as is, or close it early
• Base44 Superagent lives inside the app. Describe what you want to find out in plain words, drop in your images, and it fills in the whole study: category, type, question, answers and the success rule. Ask for changes in chat, then publish. Works on the phone too!)
• Prefer doing it yourself? The step-by-step flow has AI suggest the category and tell you why.
How it's made
Wireframes in Figma first, then the whole app was built in Base44 together with Superagent, in one chat and on the canvas, and polished screen by screen.
A few things I cared about along the way:
• A calm monochrome look in Geist with no shouting caps, so the work being tested stays in focus
• The phone isn't a shrunk desktop: a glass tab bar, a header that hides on scroll, Superagent drafts as cards in the chat
• Motion stays light.
A small dream
Big brands already hang out in comments and reply to memes. Imagine them asking people about a new icon or a small update right in a feed like this 🙂
Try it: https://alibi-app.base44.app

We created the Arrow Markets brand from zero and designed the entire Web3 trading platform including Lite and Pro modes, competition flows and advanced derivatives mechanics. The UX turns complex options logic into clear, actionable steps, while the visual identity gives Arrow a confident technical presence across all surfaces. The result is a platform that feels deep enough for experienced users yet approachable for those new to crypto derivatives.

Car interfaces keep gaining features, but experience gets lost in complexity. With River, we stripped that back: only surface what the driver needs, when they need it.
We wanted the HMI to belong to the car, not sit on top. So we designed both as one system: car, interior, cluster, main display, app.
Rive was key to bringing the whole system to life. We used joysticks and blend states to animate the cluster gauges, solos to play back a pre-rendered Blender navigation scene on the central display, and state machine inputs to bring the whole prototype to life.
We then built a companion app and plugged it into a manufacturer's API to test against real vehicle data. The app works like a key: gives you access and gets out of the way. Just the right function at the right moment.
One ecosystem where every screen earns its place.
