At SHAPE 404 d.o.o., I develop Python backends for client websites using Django, Wagtail, and Django REST Framework. I built inveraep.com from scratch, including access controls and private document storage for confidential data.

For poliklinika-aviva.hr, I integrated two external services for appointment requests and bookings, and rebuilt the booking flow patients use daily. I also built dukat.hr and two Adria Dental Group sites from scratch.

At Innovez d.o.o., I built and ran Python data pipelines for commodity trading, feeding PostgreSQL, Snowflake, and MS SQL with current market data. I also developed FastAPI services used by traders and analysts, and replaced manual deployments with chained Jenkins pipelines.

Earlier, I worked on a Windows application for automotive data processing at AVL-AST, optimized PostgreSQL queries at Intis, and contributed to backend and database integration for navigation solutions at Mireo. My computer science studies included AI and machine learning, and I built a prototype exploring news sentiment to forecast commodity price direction.
