Working in front of a computer was the last thing I wanted when I was in school. "Probably too boring", I thought. And then for some reason, I wrote my first "Hello World", following some mainstream tutorials. After that, I couldn't stop it anymore. The feeling of gaining knowledge after surpassing an at-first impossible challenge just overwhelmed me at no-return levels. Currently working as a software engineer with the following mindset: - Customer-focused decision-making - Determined to improve projects with software design principles and patterns - Working on interpersonal skills is way more valuable than on coding skills - Teamwork rocks. My technical proficiency include: Ruby on Rails Javascript HTML & CSS/SASS Minitest & Capybara Git PostgreSQL MySQL AWS

Production Engineer by degree, developer by heart. I discovered my passion for programming while in university and my aptitude for it led me to became a C-language tutor. After taking classes in the field and doing studies on my own, I decided to attend a Fullstack Web Development bootcamp using Ruby on Rails and officially change my career. My years as an engineer allowed me to have a high capability of tackling complex problems, something that I genuinely love. I was once assigned to build a compiler for a C-like language using Assembly and got it perfectly working in less then one month. The project got praised for its effectiveness and it taught me to really think of efficiency when I write my code. Most recently, I have also built and launched 2 exciting projects using Ruby on Rails and front-end technology. You are invited to visit them on my Website. I value quality and transparency in my work and I am looking forwards my next challenge as a developer. After having several experiences abroad, I’m extremely comfortable working in different environments.

Software Engineer | Data Scientist | Industrial Engineer | Researching Neural Networks and Complex Systems Hello! My name is Afonso and I have been working with VBA and Excel/Data scripts since 2016, as I used to work with demand forecasting for production lines. I have a company called 1950 Colab (which is also a coworking space in Belém/PA) and I work as a consultant for it. In 2020, I specialized with a Ruby on Rails Bootcamp and now I am pursuing an MBA in Data Science at USP using the R language and a Doctorate in Neural Networks in Mackenzie University. I really enjoy development architectures and I am engaged in back-end solutions. My main degrees are a Bachelor's in Industrial Engineering, another in Civil Engineering, and I have a Master's in Materials Engineering from Mackenzie SP (soon I hope to add the MBA from Esalq to my resume and the doctorate). I have worked with ISO/Procem management and processes for a long time, as well as agile projects, using the Scrum, Kanban, and Shape Up frameworks. I have been a manager of both large and small squads, and a course coordinator at a university from 2018 to 2021: this gave me a lot of experience with people and leadership. Nice to meet you!
