Hi, I’m Chawintee (Tob).
I’m a duct installer in Australia with a mechatronic engineering degree from Thailand, looking for my next role as an HVAC technician.
About me
I graduated in mechatronic engineering in Thailand, and I love both HVAC and electrical work. I’m installing ductwork in Australia now, and my next goal is a role as an HVAC technician, where I can grow my hands-on skills in air conditioning and electrical systems.
My engineering background helps me understand how a system is designed, how it is built, and how it should run, including the electrical and control side. I work safely, keep the site clean, and enjoy learning every new skill.
