Top SchoolJack Trefon is a seasoned engineering leader and founder with nearly three decades of software experience and a decade-plus in senior leadership, currently running Trefon Digital Consulting from Dubai to help organizations accelerate growth through pragmatic technology strategy. He has repeatedly built and scaled engineering organizations—applying Spotify-inspired team topologies and breaking monoliths into event-driven microservices for hyper-scale systems across fintech, logistics, and exchange platforms. Hands-on across the stack, Jack blends architecture, DevOps/SecOps, and product-driven delivery with people-first coaching, talent development, and organizational design. He pairs technical depth (React, Python, Java, .NET, Azure, microservices) with an entrepreneurial mindset proven by multiple leadership roles and his own media/consulting ventures. Recent MBA and DBA studies sharpen his business-first approach to tech decisions, making him comfortable translating C-suite strategy into executable engineering roadmaps.
