Freelancer profile translated to English.

Description

I am a Data Analyst and developer with experience in data analysis and web application development. I specialize in transforming data into useful information for decision-making and in creating digital tools that help optimize processes and improve business efficiency.

I work with technologies such as Python, SQL, and Microsoft Power BI for analysis, automation, and data visualization. Additionally, I develop applications and websites using HTML, CSS, JavaScript, and C#, creating solutions that combine data analysis with functional web interfaces.

I currently work as a Data Analyst within a Security team, where I participate in information analysis and insight generation to support decision-making.

In my free time, I continue to develop personal projects related to data analysis, automation, and web development, which allows me to keep learning and improving my technical skills.

I am currently looking to start working freelance, collaborating on data analysis projects, developing automated tools, and creating web applications or websites.
