DESIGN EXPERTISE
What I Bring to the Screen
End-to-End
Product Design
From discovery and user flows to wireframes, prototyping, and high-fidelity UI, I own the full design process and collaborate closely with product and engineering to ship experiences that actually work.
User Research &
Usability Testing
I use research to inform design decisions, not just validate them. That means talking to users early, testing assumptions, and iterating quickly, so the final product reflects real needs, not guesswork.
Design Systems &
Guidelines
I build and contribute to design systems that keep products consistent and teams moving fast - reusable components, clear documentation, and scalable patterns that hold up as products grow.

From Those I’ve Worked With
From Those I’ve Worked With
"As a Product manager, I worked closely with Trešnja on the GRNDHOUSE project, where she consistently demonstrated a high level of professionalism and reliability as a product designer. She was always punctual and highly responsible, delivering quality work on time and often ahead of schedule.
Trešnja has a strong ability to quickly understand complex product and business requirements and translate them into clear, well-structured design solutions. (…)"
“I truly enjoyed working with Trešnja for over a year on multiple projects and initiatives. She is incredibly fast and efficient, yet always takes the time to explain her design thinking and the reasoning behind every decision. She is highly professional with clients and truly collaborative with members of the development team. As a Product Manager, I found Trešnja to be a true partner, and I strongly recommend working with her!”

“Trešnja is a great designer, a hard worker, and an all around pleasure to work with. She knows how to communicate her ideas well to both the client, and the development team, and is always looking for the best solution for everyone. I highly recommend working with her!”
"Trešnja was a highly dedicated and responsible designer with a strong eye for detail and a genuine commitment to quality. Her work could always be trusted, whether it came to deadlines, complex tasks, or team support. She was always willing to help and contribute positively to the team environment. Working with her was a real pleasure, and I highly recommend her to anyone seeking a reliable and passionate designer."
"Working with Jelena has been an excellent professional experience. Her structured guidance and clear expertise significantly contributed to the development of my skills. With her consistent support and practical insights, I was able to secure my first role in the field shortly after our collaboration. I appreciate her professionalism and look forward to the possibility of working together again."

"Trešnja consistently delivers strong work by questioning assumptions and understanding context before diving into design. She's technically sharp with UX principles and applies them pragmatically. Her interfaces work well because she thinks through actual user needs, not just aesthetics (though her interfaces and illustrations are genuinely beautiful!).
She's also reliable: quick to respond, fast to iterate, and doesn't need hand-holding. What sets her apart is that she pushes back when something doesn't make sense and offers better alternatives instead of just executing requests."

USABILITY MINDSET
How I Got Here
Interior Design
Spatial Thinking
Studying interior design taught me that space guides people, not just fills it. I carry that same instinct into digital interfaces - thinking about flow, hierarchy, and what the eye finds first.
Literature & Language
Words Shape Experience Too
A background in literature made me obsessive about clarity. A well-labeled button, a helpful error message, a logical flow - these aren't afterthoughts in my process. They're part of the design.
Customer Support
I've Been on the Other Side
Years in customer support showed me what it feels like when a product fails its users. It made me a more empathetic designer, one who thinks beyond the happy path.

Graphic Design
Design First, Pretty Second
Coming from graphic design means I think about aesthetics with intention: typography, color, composition. Not to make things pretty, but to make them work harder for the people using them.
