An experienced software developer with a passion for tinkering

About

I’m a experienced software developer with a diverse background, particularly in healthcare, where I spent the first 11 years of my career. My passion for technology started early — I’ve always been a bit of a 'nerd,' fascinated by all things related to computers. I got my first PC at the age of seven, and although I wasn’t doing anything particularly useful back then, I remember stumbling upon Visual Basic 3.0 and experimenting with it, sparking a curiosity that never faded.

My real interest in programming took off during my teenage years, spurred on by friends who were also into coding. At the time, I was more focused on hardware, building various devices like WLAN antennas and serial port gadgets. I learned a lot through trial and error, even sacrificing a few old motherboards along the way. It wasn’t long before I started writing drivers and software for the devices I built, merging my interests in hardware and software.

Since then, I’ve continuously explored the intersection of hardware and software, and my enthusiasm for even the smallest electronic or computing challenge remains strong. Today, I work as a full-stack developer and consultant. Even now, I find myself tinkering with devices early on Saturday mornings before my wife and kids wake up—proving that my passion for technology is as alive as ever.
