Open to opportunities

I turn complex enterprise problems into systems that actually work

I work on complex B2B platforms where the obvious solution usually isn’t. Most of my time goes into figuring out messy workflows, designing for multiple user roles, and making powerful tools feel simple enough that people actually use them.

Precision, collaboration, and a lot of spreadsheets

I'm Jelena, a Senior Product Designer based in Zagreb, Croatia. For the past 7+ years I've been designing B2B tools and consumer apps in sports tech, security, document management, and SaaS. Some were startups figuring things out, others were bigger companies with established products.

I always start by talking to the people who'll actually use the thing. I care about the craft (type, spacing, interaction quality), but I care more about whether the product actually solves the problem it's supposed to solve.

I'm open to new opportunities right now. If you want the full work history, it's on my LinkedIn.

What I can do for you

Most of the work I do falls into one of three categories, depending on where you are with your product.

Ship a new product from zero

  • User and problem discovery
  • Information architecture and user flows
  • Wireframes, UI, and prototypes
  • Usability testing and iteration
  • Developer handoff and launch support

Fix a product that is not working

  • Usability testing of the existing product
  • User interviews to surface mental models
  • Flow and interaction redesign
  • Mobile-first or responsive rework
  • Before / after validation with users
Example case study Document Scanning SDK

Scale design across your team

  • Design system audit and extension
  • Research practice setup and templates
  • Workshop facilitation with product and engineering

Selected projects

Enterprise CMS dashboard with channel-based navigation
Web platform Sports media Multi-channel CMS

Enterprise CMS Platform

Redesigned a multi-channel CMS used by 12 professional sports clubs. The old system was organized by content type, but creators think in teams. I flipped that around.

Document Scanning SDK interface
Mobile SDK Usability testing iOS & Android

Document Scanning SDK

This SDK had a 70% failure rate. I ran two rounds of usability testing with 10 participants to find out why, then redesigned the scanning flow so it actually worked.

Responsive reservation app interface
Responsive web Travel & booking Mobile-first

Responsive Reservation App

The booking flow demanded exact dates, but people planning camping trips are flexible. Most searches returned zero results. I redesigned it around how people actually plan trips.

Security guard management system dashboard
Web + Android Field operations Offline-first

Security Guard Management System

Guards walk tours in basements and garages with no signal. Managers need to know tours are happening. I designed a web dashboard for managers and an offline-first Android app for guards.

AR mobile app for room scanning
iOS & Android AR & visualisation White-label

AR Mobile App

See how wallpaper looks on your wall before buying it. The AR tech worked, but nobody could figure out the scanning. I redesigned the onboarding from scratch.

Meditation and spirituality app
iOS & Android Wellness Solo design

Meditation & Spirituality App

People were googling prayers instead of opening the app they'd already downloaded. I interviewed 13 users and designed something simpler around their daily routines.
