Hire junior freelance Ruby on Rails developers in United States

My journey as a developer started when I was selected to build internal software for my college to track exchange students. With little more than curiosity and determination, I dove into Ruby on Rails—and I haven’t looked back since. Since then, I’ve worked on meaningful, real-world Rails applications like CancerCare, where I helped modernize a legacy codebase for a national nonprofit. I improved performance, redesigned the UI, fixed long-standing bugs, and restored core features like Elasticsearch—all while learning how to work within the constraints of an active production system that people rely on daily. What makes me unique is that I’m not just focused on writing code—I care about why the product exists, who it's serving, and how to build something that lasts. I'm passionate about clear communication, thoughtful refactoring, and learning new tools that help me do better work. For example, I’ve recently built my own project, Shoe Sensei, which uses Rails, Hotwire, Stimulus, and a full testing suite to provide a fast, dynamic user experience. I approach development with curiosity and care. I like understanding how things work under the hood and making small, meaningful improvements that add up over time.

I began learning Ruby on Rails in 2018 but truly started to understand it during COVID-19. Learned to switch the code from ERB to haml for templating, server-side rendering with Hotwire/Stimulus. Analyze the code for accessibility issues and remediate as needed. Integrated HTML5 video playback, Stripe payments integration, Sendgrid email relay services, Google Cloud SDK, Heroku deployment, among others.

As a Ruby on Rails Engineer with a sharp eye for optimization and scalability, I’ve always had a knack for breaking down complex problems and building elegant solutions that work for both the user and the system. My journey started in college when I found myself fascinated by the logic behind web applications. Once I built my first simple site using Ruby, I was hooked—it felt like creating something from nothing and was both challenging and exciting. Since then, I’ve honed my craft, focusing on scaling applications, optimizing database performance, and implementing robust, user-friendly APIs. One of my recent milestones was leading a team to overhaul a legacy Rails application that was becoming increasingly difficult to maintain. We implemented a well-structured CI/CD pipeline, reduced technical debt by refactoring old code, and created automated tests that improved the deployment speed and reliability. The project ended up reducing operational downtime by 30% and was a game-changer for the team and the company. It's moments like these that show the true impact of thoughtful development. What sets me apart is my unique blend of deep technical skills and the ability to look at the bigger picture.
