    Hi! I'm Pedro, an Argentine-Italian professional based in Brazil since 2018. After seven years of working in the advertising and social media field, I decided to migrate to the technology area. I did a six-month bootcamp where I learned the basics of Front-end and Back-end development, using JavaScript. Following that experience, I decided to specialize in the QA area. I started doing a Testing Manual course and, since then, I've been acquiring knowledge in this field in a self-taught way. Right now, I'm looking for opportunities as a QA Analyst, while contributing to the open-source academy UPEX, a reference in the Spanish-speaking testing community. With them, I gained experience in a real work environment, using tools like Jira and Xray and processes like BDD, with Gherkin. Also, I've just finished a Cypress bootcamp, where I was able to develop a full project for E2E and API testing, using JavaScript, Node.js, Page Object Model, Custom Commands, Cucumber, PostgreSQL, Gherkin, Allure Reports, and clean architecture. Besides that, I'm currently learning automation with Selenium and Python, BDD, SQL, and API Testing (with Postman). Regarding soft skills, I consider myself an organized and meticulous person, and I like being part of projects that aim to deliver quality products and services. I'm interested in sports —football, especially—, politics, history, geography, and education. Also, I developed a project as a volunteer in a school in Salvador, Brazil, where I created a workshop for teenagers focused on social inclusion.

    I've been working with web development since 2016, having experience mainly with HTML, CSS, Javascript and Bootstrap or using Wordpress. I'm also a Graphic Design technician, having specialized lately in interface design based on UI/UX principles. For me it's important to have clear communication between professional and client, in order to get the better results. I am one of the inventors of a patent filed with INPI (Brazil) in 2020. And I have participated in continuous innovation projects since 2017, in areas such as education, government, product engineering and civil construction, where I was able to act as a developer of MVPs and coordinator of 16 interns from France and the United States, and using agile methodologies, such as Kanban, to manage them. I'm easy to learn and always look for more efficient ways to solve problems, based on creativity.
