Turning ideas into websites and apps
Hey, I'm Rotondwa — a Web & App Developer building clear, useful experiences for businesses and everyday users.
I'm a Web & App Developer based in South Africa, building websites and cross-platform mobile applications. From the first idea to deployment, I focus on clear interfaces and practical digital experiences.
When I'm not writing code, I'm studying UI/UX patterns, exploring new frameworks, or mentoring other developers in the South African tech community.
Mobile-First
I build apps for iOS & Android that feel native, fast and delightful.
Cross-Platform
Flutter & React Native let me ship to both platforms from a single codebase.
Clean Code
I write maintainable, well-structured code with clear documentation.
Performance
Optimising startup time, frame rates, and bundle size is part of my process.
