About Me
Sphesihle Mlanzi
I am an AI Full-Stack Developer based in Johannesburg, South Africa, focused on building intelligent, scalable web and mobile applications using modern technologies and AI-assisted development workflows.
With a background in graphic design and 3D artistry, I bring a strong eye for user experience and visual clarity into software engineering. This creative foundation combined with hands-on full-stack development, allows me to design and ship production-ready systems that are both technically robust and user-centric. I leverage technologies such as Next.js, TypeScript, modern frontend frameworks, and AI APIs to build end-to-end solutions from clean responsive interfaces to scalable backend logic and AI-powered features. I have collaborated on real-world projects including CareerDash and BrainBox AI, gaining practical experience across the full development lifecycle, including development, testing, and deployment.
My approach emphasizes clean code, scalable architecture, performance, and practical AI integration. I am highly adaptable, continuously learning, and driven by building impactful digital products that solve real-world problems.
