Hello, I’m Mark Stephen Fernandes, a Senior Unity Developer with 8 years of experience building multiplayer, mobile, and cross-platform games using Unity and C#. I specialize in gameplay systems, UI/UX, multiplayer integration, cloud-connected applications, and performance optimization across mobile, PC, console, and WebGL. I bring 12 years of overall software development experience, including enterprise and backend-integrated systems.
I also leverage AI-assisted development (Anthropic Claude and GitHub Copilot) for rapid prototyping, debugging, and accelerated feature delivery. I thrive in collaborative, Agile environments and have contributed to cloud-gaming prototypes and streaming-platform integrations while coordinating with designers, artists, and backend engineers to deliver polished, scalable experiences.
