Rockstar🎓
Top SchoolNikola Zivkovic is a founder and CTO with nine years of hands-on experience turning complex systems into simple, scalable products, currently leading post-acquisition technology transitions at Corsearch after steering Sentryc from startup to multi-million ARR. He focuses on making more with less—driving clarity, automation, and efficiency to cut manual work and improve margins while preserving product-market fit. As founder of Rubix Code and co-founder/CTO of fixAICode he blends AI-first architecture, human-in-the-loop workflows, and rigorous trust/security practices to ship reliable, cost-efficient systems. A published author of two practical machine learning books and frequent speaker on AI and engineering leadership, he pairs technical depth (from SCADA to production NLP) with a founder’s product instincts and measurable operational impact. Based in Berlin, he brings a rare combo of M&A integration experience, engineering culture-building, and a track record of turning ambiguous goals into shippable roadmaps.
