Hey! Welcome to my digital portfolio.

Here you can find some projects I’ve developed over the years, as well as a bit about my skills and my academic and professional journeys.

About Me

Who am I?

Hello, my name is João Víctor. I’m interested in research and innovation! I have experience in quantitative and qualitative research, navigating across different fields of knowledge, such as Exact Sciences (Physics, Chemistry, and Mathematics), Programming, Education (and Special Education), and User Experience.

I’m always studying and learning new things, such as my recent Cloud Digital Leader certification (Google), and I strive to stay updated in the areas where I have greater expertise, such as research and development, diversity and inclusion, digital accessibility, assistive technologies, and user experience research, as well as data analysis and science.

Recently, I’ve been focusing on enhancing my skills in research, cloud computing, and data science using SQL (PostgreSQL), BI (Microsoft Power BI), R, and Python – emphasizing data visualization, statistical analysis, machine learning (ML), and artificial intelligence (AI).

Feel free to contact me.
