Josipović.

I build full-stack systems for companies that can't afford things to break — e-commerce platforms, custom CMS, and the APIs that hold enterprise operations together.

01 About

Software engineer with 2.5+ years building full-stack web applications for enterprise clients — companies with 100+ employees where downtime and bad data aren't an option.

My work spans the full stack: from database architecture and query optimization to the front-end interactions users actually touch. I've integrated payment gateways, WHMCS billing systems, domain/WHOIS APIs, and built custom CMS platforms from scratch.
