I'm Dejan Tomazin, an independent product designer with 15+ years of experience building SaaS, enterprise, and AI products. Today, I combine product strategy, UX, and AI-powered development to turn ideas into testable prototypes in days, helping teams validate ideas, reduce risk, and build with confidence.
Product Designer — Slovenia
Platforms across enterprise SaaS, AI, and product ops. Most of this work sits behind NDAs, so what's public stays high level — the full case studies are a conversation away.
A large-scale work management ecosystem — projects, resources, budgets, approvals, and forecasting — used daily by teams who plan and deliver operational work.
What I owned
An AI platform where product teams create research-backed personas and interview them through conversational AI — turning static research into something you can actually talk to.
What I owned
One place for product teams to run development from discovery through delivery, instead of scattering decisions across a dozen tools.
What I owned
Design systems that keep multiple products and teams consistent — tokens, components, documentation, and the adoption work that makes a system actually stick.
What I owned
On an intro call I'll take you through the work in detail — the problem, the constraints, the decisions, and what shipped.
Focused engagements with one senior designer. No account managers, no handoffs, no junior team doing the actual work.
One senior designer who owns the whole thread — from the first strategy conversation to the shipped interface. No handoffs between strategists, researchers, and designers. Just me, accountable for the outcome.
Best for: Teams that need senior design ownership without building a design org.
From idea to a working prototype in days. I design and build interactive prototypes in code — real flows with real interactions you can put in front of users, stakeholders, or investors.
Best for: Founders and product teams that want proof before committing a roadmap.
Also happy to help with Product discovery · UX research · Design systems · Design audits · Product strategy.
Not sure which fits? Let's figure it out on a callCurrently focused on
Hi, I'm Dejan. I've spent 15+ years designing software, and the last few figuring out how AI actually fits into a designer's day. For me it's not a gimmick — it's how I get to good answers faster and spend more of my time on the parts that matter.
I'm the kind of designer who writes the brief, maps the flow, builds the prototype, and stays in it until it ships. When you hire me, you get one person who closes the gaps between product, design, and engineering — instead of a handoff chain.
Most of my work has been in complex SaaS, enterprise tools, AI products, and design systems — places where the details carry real weight. I judge my work by what changed for the people using it, not by how the file looked in Figma.
On the future of design
“The strongest designers are comfortable stepping into unfamiliar areas, learning fast, and helping wherever the team needs them. In AI-driven teams, the biggest impact comes from people who can connect design, product thinking, systems, and execution together.”
Not rigid, but repeatable — the rhythm I bring to most engagements, tightened up by AI at every step and adjusted to fit how your team works.
We start with your users and your data. I talk to customers, dig into what's actually happening, and find where the real opportunity is.
Frame the right problem and agree on what success looks like before designing anything.
Design and prototype, often in code, using AI to get from idea to something testable in hours.
Put it in front of real people, in the real product where I can. Learn, then adjust.
Stay close to engineering through launch. I don't hand off and walk away.
Watch the metric we set out to move, and keep improving from there.
