    Hello! I am a computer engineer working with mobile development, specializing in Android UI development. I worked on mobile projects, such as health, finances, e-commerce, and well-being. With the diversity of the projects I worked in, I implemented several types of screen and UI components, such as: - Sign up and login; - Lists; - Product details; - Search with filters; - Scanners (QR Code and Barcode); - Product checkouts; - Video; - Notifications; - Forms; - and many others. I specialized in UI development because I enjoy studying and thinking about UX, but I'm also comfortable with working with everything in the Android environment. I was part of the development team of the Medite.se app, a meditation app that was awarded the Hidden Gem Award in the Google Play Store, in 2017, as one of the best apps released in that year. My work experience in different companies allowed me to participate in the whole development cycle, from the requirements definitions, through development, testing, deployment to Google Play Store, and maintenance so I can assist you in every step. I have a passion for excellence, and I am always looking to develop pixel-perfect UI. I am constantly studying and practicing to improve my knowledge and skills in pursuit of mastery. I look forward to working with you!

    I am creative, curious, analytical, and often considered a "Problem-Solver" at work. Having ease at learning new applications and programming languages by myself, I love to dive deeper into new concepts and tools of Software Development. I have a bachelor's degree in Computer Science. I have been working on the solution of scalable microservices on Java Spring Framework, in order to deliver new features used on multiple Client applications. Check below my main experiences: • Design and development of scalable microservices integrated with RESTful HTTP APIs and Messaging Brokers (Kafka and IBM MQ), based on Hexagonal/Clean Architecture. • Creating and deploying CI/CD solutions on OpenShift with Jenkins and AWS. • Projects implemented with Java Spring Framework, using Spring Boot with dependency management through Maven and code versioning by Git. • Automated testing practices using Testing Pyramid (Unit, Integration, and Component tests automation) to have a maintainable test suite. • Problem prospecting and solving using Observability tools such as Amazon CloudWatch, Splunk, and Grafana. • Experience at DevOps culture and Scrum Methodology working with synergic squads to design and build high-end applications and use of the project management platforms JIRA and Confluence. As I have a great interest and love for video games, I have been studying Game Programming in my spare time, mainly C++ programming and Unreal Engine development.
