ABOUT ME
A builder mindset, from software to physical technology.
I work across software development, mobile applications, web systems, APIs, automation, data and technology projects. I enjoy taking an idea from a rough concept to something people can actually use.
My work also extends beyond the screen. I explore ESP32/IoT projects, smart-home ideas, LED installations, solar technology and practical DIY systems.
Rangelinks SA Technology brings these interests together through technology solutions, software, data, devices and digital products.
