About

I’m Goran Sikimic, a Technical Lead and Senior Full-Stack Engineer based in Split, Croatia, with 8+ years of experience delivering production-grade web, backend, and mobile systems. I enjoy turning complex product requirements into reliable software, staying hands-on from architecture and implementation through deployment and production support.

In recent roles, I’ve led end-to-end delivery across teams, designing production applications with Java/Spring Boot, React/Next.js, PostgreSQL, Docker, and OAuth/OIDC (including Keycloak). I also build AI-enabled workflows that connect LLM capabilities with business context and integrate with tools like email/CRM/calendars, messaging, and external APIs—always with a strong focus on CI/CD, security, and real-world troubleshooting.
