PROFILE
My career started with Java and NodeJS. Over the past few years, recognizing the importance of cloud technologies, I have focused on developing Cloud Native applications with a DevOps and Lean mindset. Passionate about coding, I have recently broadened my skills to include Go. I believe that when a team comes together, the collective output exceeds the sum of individual efforts, making teamwork a case where 2+2 truly equals 5.
