Digital Product Design & Prototyping

Prototyping, design systems and engaging experiences for web, mobile and XR.

Cross-platform design for a 360° product experience for cultural heritage sites.

No-nonsense design that "just works" — that's my philosophy. Design that’s simple, functional, accessible, performant and pleasing to the eye.

New projects start with an analysis phase of a few days. That is often followed by some market and user research, inspiration board creation, and then the actual Figma design work itself. The deliverable always includes a Figma project laying out the UX/UI design, and can also include a prototype, a design system and a user testing report.

Just like an architectural blueprint, my design work sets the creative direction for the project. This means that stakeholders know exactly what will be built, and software engineers know exactly what needs to be built. Essentially, it demystifies the project and creates clarity and a product vision.

Damir is a *true* UX designer: when he works on something, from the tiniest little feature change to the biggest all-new project, his goal is to solve a problem for the user. Not only does he have a great sense of style and balance - he is also able to perfectly combine aesthetics with user needs. And to combine both with business requirements and goals.

If a picture is worth a thousand words, then a prototype is worth a thousand requirement specification documents. Prototypes are the birth of an idea into a tangible form and they are invaluable.

The logic behind a prototype I created for machine learning app.

Prototypes take me from a few days, to a few weeks to create. Building the full product often takes many months. We can start validating product ideas with about 1/10th of the time and budget by first building and testing a prototype. Does the potential audience "get it"? Would they know how to use it? Does this idea hold water, or do we need to go back to the drawing board? If we need to change course, we want to find out now. Not months from now. And, that's why prototypes are invaluable.

I use Figma for prototype creation. It's my all-in-one design, prototyping, and dev handover tool.

Take some of my prototypes for a test drive:

Testing Prototypes

I validate our idea by testing the prototype with potential users.

If the prototype tests well, we'll move to the development phase with confidence. If not, we'll change direction, and try again. Most times I hit the mark pretty close on the first go, and after some quick fine-tuning the development can start.

User testing report

I'll summarise all the insights gained from the user testing, and on most projects I'll send an email or chat message highlighting what I've learned and my recommendations for the next steps.

Different user research reports from quick status update messages to in-depth multi-page reports. Small projects need fast turnaround, and quick and short dot points for next steps. Big projects sometimes require a more thorough testing strategy and analysis.

Unless specifically requested, I don't prepare the long and boring user testing reports that are common in the industry. Most stakeholders don't care for long academic reports. Instead they just want the key insights in a short and snappy way, so we can continue work. And that's what I deliver.

Design system creation

Delivering a bunch of static Photoshop mockups is so 2010. Frameworks like Material Design, Carbon and Bootstrap have paved the way for design systems. In a nutshell, design systems make for scalable design. Scalable design makes for scalable products, and scalable products make for scalable and financially successful businesses.

Customised Material Design components.

For fast-turnaround projects I regularly utilise Material Design as a foundation for new design systems. Material design is incredibly flexible, comes with dozens of UI components ready to go, and with tools like Material-UI React library it makes dev handover easy on React codebases. And if you do it right, as I do, the end result doesn't end up looking like a typical Google UI. As I said, it's flexible and can be customised to any brand or creative direction.

I helped create the Orpheus UI library which utilises Storybook and Material-UI to quickly set up a design system for an archive product in the humanities.

Even for larger projects I default to starting with the material design approach because it's a fast, tried and proven method. But for some projects, like iOS apps where Material Design isn't applicable or some projects where uniqueness is key, I'll start with a completely blank canvas.

Designing for web

I've designed responsive, performant, SEO-friendly and accessible websites for Envato,, the New South Wales government, Harvard University professors, and many startups.

Designing the web experience for the NSW Climate Data Portal.

I both design and develop web UIs. On some projects I lead the design effort, and hand over design deliverables to devs. On other projects I go all the way and code up the UI using HTML/CSS/jQuery. More on my web dev skills.

Dark UI design is a niche specialty of mine. This isn't yet a mainstream expectation, but more and more web sites and apps are adding support.

Designing for the web requires more than just an eye for design. One must think about the limitations of web technologies, and create a universal experience for an ever-growing list of browsers and devices. Simplicity is a designer's best friend when designing for web.

Designing for mobile

I use the same prototyping process that I describe above to create high-fidelity, engaging experiences for iOS and Android. My design philosophy is heavily influenced by Apple and their motto "it just works". I'm a big fan of simplicity and I'll often reference great apps like the App Store app, Twitter, Slack, Telegram, Spotify, and others, during my app design process.

I aim to create a balance between creating bespoke components and utilising native components, and further balancing the differences between iOS and Android. But what always matters most is that the app produces the desired outcome — that users love it, that it's easy-to-use, and that it keeps users engaged.

Designing for XR

AR and VR have become mainstream thanks to technology like ARKit and Oculus Go. I have lead the design efforts on a dozen different XR projects for Harvard University professors and archaeologists.

Augmented Reality

Great AR apps feel like magic. Most late-generation smart phones support AR, so it's far more accessible than VR, and it encourages the user to experience the world around them instead of being a couch potato.

Some of the many AR projects in the humanities and archaeology space that I've lead design efforts on.

I lead the initial kick-off on these projects, painting a picture of what's possible for clients, and helping my dev team by creating a prototype which clearly illustrates how the app is to be built.

Testing an early build of an AR app for Zhejiang University Museum of Art and Archaeology. Museum visitors see artwork magically come to life on their phone.

What I loved most about these AR projects were the "wows" and the astonished reactions we'd get from clients and users.

Virtual and Mixed Reality

VR is as innovative and immersive as it gets. I have previously written about my experiences with the state of VR design. The state of VR design is still in a messy, early stage. It's easy to make bad design mistakes if not careful, and a poor experience in VR means literally making your users nauseous. A good designer will know how to avoid that by taking into consideration a vast number of spatial design and ergonomics factors when designing for VR.

I helped improve the user experience of education apps for Harvard University. Here we have a mixed reality experience where students are given a tour of the Giza plateau guided by a professor of Egyptian studies.

Mixed reality is a lighter way of experiencing virtual spaces. It's less immersive, but also less dizzying, safer, and one can still see and interact with people and the environment around them. Therefore it's well suited for classroom learning and museum group tour experiences.

While XR is more complex than digital design for 2D user interfaces, my traditional design process still applies. Like on every project, I become familiar with the requirements, run collaborative workshops as needed, visualise the end goal, design an engaging prototype that I test on potential users, and deliver detailed mockups that guide the development team during the build.

360° Tours for the Web

The most accessible way to experience virtual spaces is on a good old web browser — whether on phone or laptop. In terms of global reach the web is still the gold standard. Not as big of a wow-factor as AR or VR, but more comfortable (meaning longer sessions) — and more accessible to people with disabilities.
