Hire freelance Ruby on Rails developers in United States

As an accomplished senior Full Stack developer with 9 years of mastery in Ruby on Rails and Single Page Application (SPA) development using React, Vue.

My strength is working with the non-technical. If you're here, you probably know what you want or need, but maybe you don't know how to best accomplish it. I can help with that. Do you need someone who understands projects might have many stakeholders and need to be ready to pass along or pick up and pivot? I'm here for that. I'm currently open for project-based work. If you need something done, and need someone who can do it with as much or as little help as possible, let's talk. My stats: I'm a senior dev (10 years in Rails, 20 in web dev) who's been through dialup (14,400 even), Flash and ColdFusion, DHTML, I remember when JavaScript was invented, and I provision servers for fun. I'm a Rails dev who aligns closely with the Rails ethos on most things. Importmaps and Hotwire and Turbo and Stimulus are great fun. Familiar with teamwork (read: merge conflicts) and maintaining healthy relationships (read: no ego, just aiming for the best code). If none of that means anything to you, then all I'm bragging about is that I know how to start from nothing and build an entire infrastructure. I can work with a team or by myself equally well. If you know exactly what you want: shoot me a list. If you're a bit lost: let me help. If nothing else, I'm thrilled that I might get to talk shop with new people. Tell me about your project!

I'm a full stack (plus devops, plus data eng) developer with a penchant for human interaction. In the past, I've thrived in "solutions" roles, I've gotten a solid start on management skills, and I've helped launch many a startup. I love mentoring junior devs and helping a company have an excellent technical and social culture. You might also like my full Ruby Conf talk from a few years ago (it's a good simple intro!) - https://www.youtube.com/watch?v=dXCvQCOZs78 I can help you bring your idea from zero to launch - literally every step - from ideation and product to traffic analysis and hosting, and of course what we're all here for: ruby code :)

I am an accomplished Head of Engineering with over 9 years of experience driving innovation and leading high-performing engineering teams. Throughout my career, I have consistently built and scaled engineering organizations, delivered complex software solutions, and driven significant business impact.   My "developer origin story" is grounded in hands-on software development. I honed my skills in Ruby on Rails early on, and I'm particularly proud of my commitment to quality, like when I took untested production apps to 95% code coverage. This foundation as a developer deeply informs my leadership approach, giving me a strong understanding of the challenges and opportunities my teams face. A recent highlight includes my time as CTO at Sonatafy, where I developed AI screening to improve hiring and recruiting efficiency.   Building and scaling teams is a passion of mine, demonstrated by my experiences at Spring Health and Freshly, where I rapidly expanded engineering teams while maintaining a focus on delivery and quality. I excel at connecting technology with business strategy, and I have a proven track record of driving key business metrics and reducing costs through innovative solutions. For example, I owned the engineering of an internal EHR at Spring Health, which decreased expenditures in the tens of millions annually.   My unique skills lie in the blend of my technical expertise, strategic thinking, and leadership capabilities. I'm adept at system architecture, project management, and IT strategy, with a focus on fostering collaboration and enhancing operational efficiency. I believe in investing in people, and I am committed to mentoring, training, and guiding teams, even through complex transitions like the billion-dollar acquisition I navigated at Freshly.

I'm Matt Lins, and I have an extensive 18-year background in web development, specializing in Ruby on Rails. I've applied my craft to build scalable E-commerce, Healthcare, Proptech, and iGaming sites. Along the way, I've led engineering teams to achieve company exits, and in doing so, I've learned that the most sustainable code and tech solutions emerge from the pursuit of simplicity. I advocate for simplicity in development - a belief deeply rooted in the principles of Gall's Law, which I see as essential for creating solutions that focus more on business value than technical complexity.

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.

Hi, I'm Mike. Over my career, I've worked at a variety of companies of different sizes and problem domains. I've seen a lot of what works and what doesn't, so I think I can provide insight on processes and approaches to common problems teams run into. I do my best work when given a goal. I like to focus on the product first and the rest can always be improved upon later. I'm big on testing and I use TDD often. TDD helps me move quickly. As the first hire at a fintech startup: * Built and launched the initial version of the product. * Interviewed candidates for both technical and behavioral assessments. * Recognized as employee of the month in Feb '23 for embracing ownership. I came up with a way to reduce the company's risk. * Recognized as employee of the month in Jun '23 for embracing simplicity. I helped launch a large feature in a short amount by working closely with product to reduce the scope. * Built, maintained, and improved the core product that has led to a Series A.

I am a Ruby on Rails Expert with 10+ years working independently to help companies of all sizes. I work with small but profitable SaaS companies that don’t have a dev team. I manage their entire tech stack—everything from infrastructure to product strategy to building their Rails app—so they can grow without worrying about the technical side of things. I have worked on and upgraded all major Rails versions. I am not only a developer, I am your business partner and advisor with a deep understanding of what it takes to deliver mission critical software. I have DevOps experience administering production systems on AWS and other platforms. I understand software quality and can help you with process improvement.
