I’m Rafael Zuniga, a Senior Game & Software Engineer with a track record of turning ambitious ideas into fully developed, scalable products. Over the past 8+ years, I’ve built scalable game architectures, market-ready multiplayer games, cloud-integrated applications, and Web3-enabled experiences—bridging the gap between game development and high-performance software engineering.
I specialize in designing and executing complex systems, whether it’s real-time multiplayer networking, scalable backend infrastructure to UI/UX-driven interactive experiences. I thrive in fast-paced, high-stakes environments, leading lean teams to ship high-quality software efficiently.
With a deep understanding of cross-platform development, AI-powered tools, and cloud-based solutions, I focus on building modular, maintainable architectures that allow products to evolve and scale. Whether launching a new product, optimizing live operations, or integrating cutting-edge technologies, I bring a detail-oriented, solution-driven approach—where performance, usability, and visual polish work in harmony.
