Introduction

Hi, I'm Petar Trifunovic.Full-Stack Developer &UI/UX Designer

Fifteen years of building for the web, from small sites to full production systems.

I build web applications from start to finish, from the database and API design to the interface people actually use. I care just as much about how something works underneath as about how it looks on the surface.

Building Scalable Digital Solutions

From concept and architecture to development, testing, and delivery

AtlassianTools and Techniques

I work across the whole stack. On the server that means data models, REST APIs and the authentication around them; on the front end, the interface those APIs feed. Recent work includes an HR platform with interactive org charts and Excel and PDF reporting, and a studio site with a custom rich-text editor backed by its own publishing API.

I also own what happens after the code is written. That means end-to-end tests before a release, an API hardened against the usual abuse, and the production servers themselves: provisioning, reverse proxy, automated backups and the deploy that ties them together.

Web Design - UI/UX

Designing intuitive, modern, and engaging digital experiences

AdobeMaster at Adobe

I focus on creating visually refined and user-centered digital experiences that combine aesthetics, usability, and functionality. My goal is to design interfaces that are intuitive, accessible, and easy to navigate while helping users interact with content in a clear and meaningful way.

Beyond visual design, I transform UI/UX concepts and wireframes into fully functional, responsive interfaces. By bridging design and development, I ensure consistency across the entire user experience while delivering modern, high-quality web solutions optimized for performance and usability.

Most projects split those three across two or three companies, and the loss happens at the seams. Here is what gets lost, and what you are left holding at the end.
