I'm a Mobile App Developer crafting high-performance. Specializing in React Native and cross-platform development, I turn concepts into polished, scalable mobile experiences that users love.
Turning ideas into apps people use
Hey, I'm Rotondwa — an App Developer passionate about crafting mobile experiences that are intuitive, performant, and genuinely useful.
I'm a passionate App Developer based in South Africa, specialising in building polished, high-performance mobile applications for iOS and Android. From concept to deployment, I turn ideas into intuitive digital products that make a real impact.
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.

App Developer
Freelance
App developer building and shipping personal projects while taking on focused freelance work.
- ▸Building 2 personal mobile apps in active development
- ▸Shipping with Flutter and React Native using Firebase and Supabase
- ▸Driving projects end-to-end from concept to release-ready builds
- ▸Implemented PWM motor drive with H-bridge control, ADC-mapped joystick input, interrupt-driven timing, and a deterministic state machine for autonomous routines with manual override
Robotics Programmer
Robotics Build
Programmed robot motion control with autonomous and manual driving modes for a successful build demo.
- ▸Implemented PWM motor drive via H-bridge control for precise speed and direction
- ▸Mapped joystick input through ADC sampling and input scaling for smooth manual control
- ▸Built a timer/interrupt-driven state machine for autonomous movement sequences
Robotics Design
Prototype Build
Designed a robot concept from app-based modeling through 3D-printed prototype preparation.
- ▸Created the robot design in a mobile design app and refined the model for build readiness
- ▸Prepared the model for fabrication in Creality for 3D printing
- ▸Produced a printable prototype to validate fit and form
