Hire freelance Ruby on Rails developers in Brazil

Production Engineer by degree, developer by heart. My passion for programming started when I was still in university, where I became a C-language tutor. In 2022 I decided to officially start my career as a developer, attending a Full-stack Web Dev bootcamp. One of the accomplishments I take pride in is building a compiler in Assembly for a simplified C-like language. The project got praised for its effectiveness, and learning such low level languages has deepened my focus on efficiency when I code. For the past 1.5 years I have been working on a robust RoR application as a back-end engineer, gaining experience in some key areas like: - API integration - Test-Driven Development (TDD) - Debugging - Database manipulation and query efficiency - Building and maintaining background jobs I pride myself on having meticulous and analytical thinking. I don't just enjoy solving problems; I strive to analyze all the potential consequences for application functionality and the end user experience, ensuring I come up with the best possible solutions.

I've been building and maintaining Ruby on Rails applications of all kinds and sizes since 2013, always trying to apply the best practices and community conventions. I'm studying more about AI and ways to improve my work/systems with it. I created a model for my current company to predict delivery times in our platform with 84% of accuracy. I have experience working in projects from conception to release and can work at any level of the stack. I'm that nerd guy always looking at some APM tool and trying to get the best out of the language/framework. I have experience with legacy projects and enjoy solving performance related issues. Technologies I can work with: Javascript, Python, Relational and Non-relational databases, ElasticSearch, APM tools, all major cloud providers.

As a seasoned software engineer with a strong background in Ruby, Rails, and JavaScript, I have a proven track record of delivering high-performance solutions. With experience in building blazing-fast storefronts and improving memory and CPU efficiency, I excel in creating scalable and resilient systems.
