Nikola Zjacic

Software Engineer

Fueled by building stuff, fresh sneakers, and chasing goals, on and off the pitch. Based in Italy

Passionate about building things

I'm a Software Engineer based in Cervignano del Friuli, Italy working at Tinexta Cyber in Trieste. I specialize in building full-stack systems — from resilient Java microservices and Python data pipelines to interactive React frontends and mobile apps.

I care about clean, maintainable code and fast feedback loops. I actively use AI tooling, like Claude Code and OpenCode to accelerate the development process without cutting corners on quality.

When I'm not coding, I'm exploring new technologies, reading novels, or traveling to new countries.
