About

Since 2022, I started learning about Data Science as I was passionate creating solutions combining my passion for maths and computers. Eventually, I pursued a degree in data science and I enrolled in a Data Science bootcamp, which gave me the theoretical foundations of Data science. Meanwhile, I interned at a Digital Marketing small company, and worked for a company that assisted in social initiatives. Now I am seeking new challenges and opportunities to grow as a Data Scientist.
