Senior🎓
Top SchoolMario Kralj is a versatile programmer with 10+ years building full-stack and DevOps solutions across Python, JavaScript/Node.js, AWS and GCP, currently applying his skills at Júní in Reykjavik. He has led backend architecture and cloud administration for data-heavy platforms at Klappir and operated as a DevOps engineer at Controlant, blending hands-on coding with infrastructure and reliability work. His background spans web, multimedia and post-production engineering—over a decade of creating web platforms, Flash/Unity experiences and thousands of video projects—giving him a rare mix of systems engineering and creative tooling expertise. Comfortable across Linux/macOS, databases (MySQL/Postgres) and front-end frameworks, he often bridges product and operations to ship pragmatic solutions. A pragmatic tinkerer with a hacker's sense of humor (Github bio: rm -rf /*), he brings deep practical experience in turning complex requirements into reliable, maintainable systems.
