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!

Welcome! I'm Felipe, a game programmer from Brazil, currently living in Brasília. I have more than 9 years of game programming experience, developing mobile, desktop and web games for various platforms. I usually use Unity for mobile and desktop game development and Phaser for HTM5 games, but I'm totally open to use other engines/frameworks that you may think it's more suitable for your project. I have a Bachelor of Science (B.Sc.) in Electrical Engineering from the University of Brasília, UnB which helped me to develop strong math and physics skills that I can use on games to make them look even cooler and solve complex challenges. I'm still always studying and learning new stuff to improve my games' quality and to continue to deliver amazing projects. All these years working as a game programmer, I have worked both full and part time developing games of several genres and platforms for many clients from different countries. To see some of my work, please visit my personal website. I'm interested in working on both big and small projects. Let's build great games together!
