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.
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.

I was a scholarship holder in the teaching and research project titled "Introduction to programming lab for elementary school students".
In this project, I was able to teach programming and robotics to students in the final years of elementary school in public schools.
The main activities developed were: instructional resource selection, planning the class schedule, teaching "visual programming" languages (Code.org and Scratch) and programming with Arduino.
I was able to develop teamwork, didactic, and presentation skills.
I was a scholarship holder in the teaching and research project titled "Planning differentiated activities on information processing in public schools".
In this project, I was able to delve into how the field of information processing was taught in public schools and, from there, prepare materials and discussions to be brought into the classroom for students in the final years of elementary school and high school.
I was able to develop research skills, teamwork, report development, teaching materials preparation, didactics, and presentation skills.
My degrees and certifications

I improved my knowledge in Programming, Digital logic, Eletronics e Object-oriented Programming.
I developed several codes in the C Language for language study purposes.
Some of my code are at this Github repository.
During my undergraduate studies, I had my first contact with the areas of research, computing and accessibility. I was also able to develop my teaching skills, presentation skills and report writing over the years.
Throughout the course, I participated in scholarships, volunteer work and teaching internships in various subjects, such as programming and robotics, including for students in special education.
I participated in several study and research groups, represented undergraduate students, developed academic research and interned in schools that follow the bilingual model for the deaf (Libras | Portuguese).
I developed my skills in various programming languages and in the areas of gamification and accessibility in games.
Over the last years, I have completed numerous courses and certifications, from User Experience to Statistical Programming.
Some of my main certifications are
- Data Analyst Associate (SQL), at DataCamp
- Some certifications (R, Python, SQL, Power BI e Cloud), at DataCamp
