Senior Product Designer

Aleksandar Žeželj

Senior Product Designer with 12 years of solving complex problems with polished, neat, data-backed solutions and deliverables — balancing what the business needs against what the person using it actually wants.

Solid history of complementary work with other experience designers, developers, stakeholders and business leaders. Comfortable leading cross-functional teams, and comfortable going to bat for the user in a boardroom — most of the work is deciding what to leave out.

Based: Banja Luka, Bosnia & Herzegovina
Languages: Serbian (native), English, Spanish (understanding)
Status: Open to a new role

Product design experience

12+ years, discovery to delivery

A finding counts when it survives seven checks.

Interviews, prototype tests and behavioural signals, synthesised into assumptions, risks and the next thing worth learning.

Fig. 01 Touch a check

Complex requirements in, one clear path out.

User flows, information architecture and interactive prototypes across e-commerce, subscription management, admin tools, social platforms and 3D configuration.

Fig. 02 Walk the flow

Every pixel of a button is a decision. This one is yours — press it.

Responsive interfaces, design systems, reusable components and brand identities, from early concept to working product.

Fig. 03

Users, the business and engineering pull three ways. The work is keeping them on one heading.

Led UX/UI from discovery through delivery. Proposed clearer UX/UI responsibilities and recurring peer reviews to raise the whole team's design work.

Principles

Ten rules I work by

The harder a decision is to undo, the stronger the evidence.
Commitment
Fig. 01
Validation is a threshold, not a promise of certainty.
Validation
Fig. 02
The decision sets the bar.
The bar
Fig. 03
Start with the biggest unknown, not the next stage.
Risk
Fig. 04
Look for what repeats, what holds, and what doesn’t fit.
Pattern
Fig. 05
Quantity matters less than what reduces uncertainty.
Signal
Fig. 06
Decision-ready means known enough, not certain.
Threshold
Fig. 07
Trust it. Read it. Decide. Locate the risk.
The square
Fig. 08
Every piece of evidence has a home: desirable, viable, feasible.
Value

Evidence gives the next move a name.

AI practice

How I work with it

AI in the loop, judgement on top.

Fig. 01

A bad question asked faster is still a bad question.

The model: Nothing yet.
Me: The problem, the user, the constraint, and the bar it has to clear.

Fig. 02

It widens the field. I set the limits.

The model: Directions, references, copy variants, the edge cases I would miss.
Me: The limits, so the options are worth comparing.

Fig. 03

It argues back. It doesn’t get a vote.

The model: Counter-arguments, when I ask for them.
Me: Cuts nine of ten, and checks what is left against the evidence.

Fig. 04

It does the typing. I read every version.

The model: Prototypes, front-end, specs. This site was built that way.
Me: Reviews every version and sends back what isn’t right.

Fig. 05

What ships, and what happens after, is mine.

The model: —
Me: The outcome, and the next decision it leads to.
