You shoot me down, but I get up
I'm bulletproof, nothing to lose
Fire away, fire away"
Following the message of the song "Titanium" by Sia, determination, bravery, and resilience have driven me to overcome any challenge in my path.
I am a curious, creative, self-taught, and restless person. I am characterized by moving forward fearlessly towards my goals, taking advantage of every opportunity that arises, and I have a firm belief that every day brings something new to learn.
Throughout my career, I have collaborated on various projects that have contributed to my personal growth, improving my communication and self-leadership skills.
