Hire mid-level freelance Ruby on Rails developers in United States

Hi! I'm Liz 👋🏼 I'm about as full-stack 🥞 as they come. I started as a QA and automation engineer and now I'm a senior full-stack engineer focusing on Rails and React. Early on as a QA I worked on projects from writing SQL scripts to check data, to automation engineering, to React Native applications, and even helping implement Kafka instances and a team transition to Kubernetes. Then I moved on to development, mostly focusing on Rails / React stacks. I also am very comfortable working in Python. Now I've been a full stack developer for a few years, always carrying my QA mindset with me. I love exploring the ins and outs of a problem, and figuring out where I can pick it apart and expose weaknesses. I'm really great at building relationships with stakeholders, establishing trust and cooperation so that we can all move forward with a project in a very pragmatic way. Pairing with coworkers is always very enjoyable for me. I like the collaboration, but I really value the mentorship the most. Teaching juniors git has become a mainstay for me, as well as coaching them to maintain a calm mindset while debugging, encouraging them to move through issues in a systematic way. And of course I always fit in robust testing, showing folks how to create test suites and pipeline automation that will improve their workflow. Let's talk about how I can contribute to your team and stack 🙌🏻

I’m a senior developer and product strategist with 10+ years building custom software, mostly with Ruby on Rails. I turn complex problems into fast, scalable solutions—and I always build with the end user (and the business) in mind. I got into dev through entrepreneurship—building tools to run my own businesses. That mindset never left. I think like a founder, move fast, and care deeply about results. Lately, I’ve been focused on integrating AI into products: • Automating workflows with tools like OpenAI, Make.com, and LangChain • Building AI-powered features that enhance user experience and drive growth • Helping SaaS teams use AI to scale smarter without adding headcount I’ve led everything from zero-to-one builds to product turnarounds, working closely with founders and small teams. I thrive in fast-moving environments where priorities shift and speed matters. When I’m not building software, I’m in the mountains snowboarding, hiking, or chasing the next great view. Let’s connect if you need someone who can think strategically, code fast, and actually ship.

I'm a full-stack software engineer with 4+ years of experience, including 3+ years building and maintaining a scalable, multi-tenant SaaS application. I currently lead all engineering efforts at a startup — architecting systems, writing code, managing infrastructure, and owning deployments. I also collaborate closely with our small team on product planning, helping shape features and priorities from a technical perspective. I specialize in Ruby on Rails, Hotwire, PostgreSQL, and JavaScript, with a focus on clean code, high test coverage, and thoughtful, maintainable design. I’m also passionate about learning and enjoy collaborating with engineers who share a commitment to building high-quality software using best practices.

As a highly skilled Full Stack React and Ruby on Rails developer with extensive experience in a wide range of related technologies, including TypeScript, Next.js, Nest.js, Graphql Apollo, Redux, and more, I have built a strong foundation in coding through online platforms such as Freecodecamp, Codecademy, and Edx. Over the past 6 years, I have honed my skills and gained valuable experience building high-quality web applications for clients. I have a proven track record of delivering complex projects on time and within budget, consistently meeting or exceeding client expectations. I have increased test coverage up to 90%, resulting in fewer bugs and faster bug detection and resolution. Additionally, I have managed teams of developers and collaborated with stakeholders to ensure project success, building productive relationships with clients that have led to repeat business and referrals. In addition to my technical skills, I am committed to continuous learning and professional development. I have completed courses and earned certifications in related technologies, including AWS, Docker, and DevOps. I am always seeking out new challenges and opportunities to expand my knowledge and skill set.

I’m Alex Smith — a senior full-stack software engineer with over 9 years of experience building fast, elegant, and resilient systems. I began my career on Wall Street, where I developed a deep understanding of performance, precision, and high-stakes infrastructure. Since then, I’ve brought that same rigor to startups and fintech companies, designing scalable backend architectures, crafting intuitive user interfaces, and leading cross-functional teams through complex technical challenges. Whether it’s shipping high-impact features, optimizing performance, or diving deep into system observability, I bring a pragmatic, detail-oriented approach to everything I build. Beyond code, I’m a hands-on problem solver who enjoys tackling real-world challenges — from modifying cars in my garage to chasing par on the greens. I’m always exploring new tools and technologies, and I thrive in environments where curiosity meets execution.

Hello, I'm Jonathan. I like solving problems—often with code. I'm a full-stack engineer with 7+ years of experience building scalable web applications, primarily with Ruby on Rails. I thrive in environments where I can own high-visibility projects, collaborate across functions, and move fluidly between strategy and execution. I'm also very comfortable in asynchronous workflows and product-driven teams. I've built integrations with external APIs, including payment processors and Visa, and I've led projects from idea to launch. Mentorship is part of my rhythm—whether through pair programming or thoughtful code reviews. Lately, I’ve been working on a personal project: an AI-powered productivity app designed to help users set goals, track tasks, and build momentum. I care about clean architecture, thoughtful collaboration, and building tools people actually enjoy using.

Hello, I’m a software developer based in Brooklyn, NY. I moved into software after a long career in digital marketing. Ruby was the “new hotness” when I started, and ten years later it’s still one of my top choices. Recently I’ve been diving into pure functional programming with Scala 2 and front-end libraries like Effect. Rails remains my happy place -I love the autonomy and speed it gives small teams. I prefer hands-on IC work, but I’m happy to help plan and organize when needed. Colleagues and managers often describe me as someone who “gets sh*t done” - a badge I wear proudly! I’d love to hear what you’re working on. Feel free to reach out!

I am a career-changer that has always found ways to use my coding skills to enhance my value. I am seeking to transition into software development full time. As a career "pivot," I have a strong and reliable work history. I have been the director of a non-profit subsidiary, managed the development of a Salesforce platform for a program providing college education to incarcerated and formerly incarcerated students (700+ students in six locations), launched a temporary supportive housing program for formerly incarcerated college students working towards completion of their degrees, and previously worked as a paralegal at law firms defending doctors and hospitals in healthcare litigation. All of this built upon a degree in business with a concentration in mathematics. As a developer, I attended a coding boot camp focused on Ruby, Rails, and JavaScript. I have a portfolio of student projects to show for it, but most of my recent coding has focused around open source contributions to projects like Dry-rb and Hanami, including a major refactor of the Hanami Router library. I am insatiably curious and love to learn. I am an excellent communicator, with experience writing documentation, delivering talks, and teaching seminars. I believe that learning, teaching, and collaboration are the three founts of productivity and innovation. I would love to speak with you about how I can contribute to your project and team!
