What I'm looking for

I'm looking to build full-stack, eCommerce, and 3D web products, contributing hands-on across Rails, React, Three.js, product design, and backend architecture.

I'm co-founding Taman Technologies, where I'm building an AI-native urban lighting design platform. I develop its 3D web application with React, Three.js, Blender, and Python lighting-optimization workflows, while contributing to product design and business analysis.

At Ingemark, I progressed from student developer to Mid-Level Developer, Team Lead, and Senior Consultant & Engineer. I've led projects from concept to completion and now provide senior Rails consulting focused on Spree eCommerce and backend architecture.

My work includes Croatia's leading online retail platform, Konzum.hr; Pharmeria.hr, a digital healthcare solution connecting pharmacies and users; RoomOrders; and ZorroTunes. I hold an MSc in Computer Science from FER, University of Zagreb.
