Hire senior freelance Ruby on Rails developers in Brazil

Hi! My journey in software started during university, I have a bachelor's degree in Software Engineering and that’s where I had my first contact with Ruby, back when Rails was on version 3, during that time I co-founded a junior enterprise with some classmates. The idea was to apply our learnings building small systems for local businesses, using Rails, PostgreSQL, Heroku, and RSpec. And from there I never stopped learning, for the past 8 years I've worked in so many different projects for big companies like GoDaddy (U.S.A.) and Trainline (EU) and I'm sure I'll have many other challenges to overcome.

I’m a passionate Ruby on Rails developer with 4+ years of experience building and maintaining robust back-end systems, including working extensively with legacy applications. Over the years, I’ve worked with various versions of Rails, adapting to evolving best practices and technologies. While my expertise lies in back-end development, I’m also skilled in modern front-end technologies. I actively work with Vue.js, leveraging its reactivity and flexibility to create dynamic user interfaces, and I’ve integrated Hotwire to deliver fast, seamless experiences without over-relying on JavaScript. I’m always striving to improve my craft and learn new tools that make development faster, cleaner, and more enjoyable. I bring dedication, attention to detail, and a collaborative spirit to every project. I’m excited to take on new challenges and prove how I can contribute to building exceptional software.

My journey as a developer has been nothing short of a thrilling adventure, filled with continuous growth and learning. It all began back in 2010 when I took my first steps into the world of programming. The very first programming language that I got my hands on was PHP. I remember the excitement of writing my first "Hello World" program and the sense of accomplishment that followed. It was in those early days that I realized the potential of turning lines of code into functional applications. As the years rolled on, I delved deeper into the world of web development. Around the mid-2010s, I found myself venturing into the realm of JavaScript and Node.js. It was a significant shift from PHP, and it opened up a whole new world of possibilities. Building real-time applications and server-side scripting with Node.js was a whole new ballgame, and it pushed me to refine my coding skills. However, the most significant turning point in my journey occurred towards the end of 2018 when I embarked on a new adventure by diving into the Ruby programming language and the Ruby on Rails framework. Ruby's elegant and concise syntax immediately appealed to me, and Rails' convention-over-configuration approach simplified the development process in a way that I hadn't experienced before. Working with Ruby and Rails allowed me to develop web applications rapidly and efficiently, and I quickly fell in love with the framework's emphasis on developer happiness. Over the years, I've continued to grow as a developer, honing my skills in various programming languages and frameworks. Each language and technology I've encountered has contributed to my knowledge and experience, making me a more versatile and well-rounded developer. Looking back at my journey, it's clear that my passion for coding has driven me to explore new horizons and embrace the ever-evolving landscape of software development. I'm excited to see where the future of technology will take me and the new languages and frameworks I'll have the opportunity to learn and master.

I have 10+ years of experience as a Software Engineer working primarily as Full-Stack with Ruby on Rails and different JS frameworks like Stimulus, Angular and Vue. I've been working full-time for international startups for the past 5 years mainly with Ruby on Rails in the backend and also been working as a free-lancer on my free time when a good opportunity arises. I consider myself very humble and a team player where I am always trying to help my teammates with some mentorship and thought-full code reviews and working as a Product minded engineer that is aware of the bigger picture behind a product and not only on delivering task after task.
