Information About Me
When the covid-19 pandemic started, with more time at home, I
decided to go back to studying Java so I could make a career
transition (from support to programming). I took several online
courses and in April 2021 I participated in a selection process
and was one of those selected. It was my first job as a Java
programmer. Since then I've been studying and I've changed jobs a
few times, always working as a back-end and even full-stack
programmer.
In total, I have been working as a programmer for 2 years, mainly
using Java and Spring Framework technologies.
I am always looking for more knowledge, whether studying or facing
new challenges.
