Hi, I’m Nicolas Duc, a Full Stack Engineer with 8 years of experience building scalable web platforms, multiplayer systems, and cloud-native applications across enterprise software, iGaming, and digital commerce. I specialize in Unity-driven multiplayer gameplay, microservices, REST APIs, and real-time backends that power engaging player experiences. I enjoy collaborating with cross-functional teams to ship features that boost performance and player satisfaction, and I thrive in Agile environments. My background spans startups and large enterprises, with hands-on work across backend services, cloud infrastructure (AWS, Redis caching, Docker/Kubernetes), and front-end interfaces. I’m passionate about delivering robust architectures, optimizing latency during high-traffic events, and mentoring teammates to raise code quality and delivery velocity. In my spare time I enjoy exploring new game development patterns and improving live platform capabilities through iterative development.
