Freelance ConsultantMihael Janđel
Enterprise Solutions Architect
Transforming complex business requirements into scalable, high-performance software systems with 20+ years of experience.
After more than two decades in the trenches of enterprise software development—leading critical implementations for telecommunications and government sectors—I founded Mihakod. My journey from senior roles in global corporations like IBM & Kyndryl to independent consultancy allows me to bridge the gap between corporate stability and freelance agility. I don't just write code; I architect systems that are built to last.
