Roman Kozak

Software Engineer with over a decade of experience building high-performance, data-intensive applications across fintech, cloud optimization, and real-time streaming platforms. My expertise spans React, TypeScript, Node.js, and a wide range of modern JavaScript frameworks. I’ve led engineering efforts at companies like nOps.io, Phenix Real Time Solutions, Northern Trust, and N-iX, delivering scalable frontend systems and optimizing applications that handle massive real-time datasets. I’ve architected and built design systems for both fast-growing startups and large enterprises, focusing on reusability, accessibility, performance, and long-term scalability. These systems reduced development costs, improved UI consistency, and enabled teams to ship features significantly faster. As a judge, I draw on deep experience in system design, performance engineering, and practical problem-solving. I look for clarity of thought, strong architecture, clean execution, and the ability to turn an idea into something robust and production-ready. I participate in judging to support emerging engineers, share proven industry practices, and help creators build software that is both innovative and technically sound.
