UI/UX

Design-first builds

01About

Builder with a designer's eye.

I am a Computer Science graduate from the Technical University of Cluj-Napoca who cares about the full experience: how a product looks, how it behaves, how fast people understand it, and how confidently a team can keep improving it.

01

Interface systems

I turn rough ideas into clean flows, reusable UI patterns, and responsive screens that feel intentional.

02

React delivery

I build with modern React and Next.js, keeping components readable, accessible, and easy to evolve.

03

AI and data fluency

My recent work bridges frontend thinking with Data & AI training, automation, and product-oriented workflows.

I create interfaces that work clearly, move smoothly, and leave enough personality for people to remember them.

02Skills

The toolkit behind the polish.

My strongest lane is the intersection: frontend that respects design, design that understands implementation, and AI/data work that can become a real feature instead of a demo.
