Rafael S.

Vetted D3.js developer in Brazil (UTC-3)

I am a medical doctor and software engineer, passionate about developing and honing my skills in Sydney. I graduated from medical school in Brazil eight years ago and began my career in healthcare immediately afterward. My fascination with computers and systems dates back to 1995, when I started teaching myself how to navigate and utilize the emerging technologies of that time, eventually sparking my interest in creating digital solutions. Working deeply within hospitals, I observed firsthand how many inefficiencies in healthcare could be solved with technology, simplifying complex tasks and saving valuable time. Returning to Brazil during the COVID-19 pandemic due to Australia's border closures, I seized the opportunity to apply the knowledge I'd gained from international experience to advance technology in local companies. I was soon hired by a company developing a platform to address a pressing issue among medical professionals, allowing me to blend my medical insights with my engineering expertise to create impactful solutions.
