Hire medio 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 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.

💭 Do you have an idea that makes sense in theory, but you haven't gotten it beyond that point? An existing team that could use some direction? Perhaps a product that you've gotten to market, but you're finding it harder to add more and more customized features and keep it performing the way it should? 👋 For a little over a decade now, I've been building clean, maintainable, applications for everything from cyber security, high traffic (millions of transactions per day), credit products, custom learning platforms, to custom storefronts. 🤖 I take a pragmatic approach to development, I'll hear you out, ask some pointed questions along the way, give targeted feedback, and rinse and repeat until we've got a clear vision for your product. You'll be able to give feedback on quick builds that are put together in days / weeks rather than months. This process is called prototyping. 🏆 Prototypes are great, but they won't take into account all the nuances needed for a product to start serving customers, so from there we'll have a conversation about what your "must haves" are in order to get a product in front of customers. Anything that you'd like but isn't a "must" will be outside the scope. This step is where we build an MVP (minimum viable product). The goal here is to get your product to market as fast as possible. Paying customers are the best source of feedback you can get, but we need an MVP to get them in the system. From there we work on the features that you and your customers want most. I'll always give you straight talk on what options you have for various features, and steer you toward the most practical technology choices to handle the functionality you want, while also working within your budget. Core Services build a prototype or MVP jump into an existing application and work through a hard to build feature, or difficult bug improve the performance of your existing application improve your authentication layer (add popular authentication providers and protocols) improve your application security (evaluate and fix security holes, work through security questionnaires your clients send you) begin accepting payments in your application make your application mobile friendly (either using responsive / progressive design techniques or with a full fledged mobile app) give feedback on and improve your existing design Have an existing product? I specialize in performance enhancements to a product that feels a bit sluggish, as well as ensuring you can handle an expected jump in traffic pragmatic AI architecture. If you're not sure where to get started, I've already built out several multi-agent AI driven tool sets that go beyond having a context driven interaction with customers, and instead allow customers to handle complex tasks through text messaging and voice. Rails upgrades team augmentation

TLDR- I know Rails, let’s build together. I understand that the most important part of any project is getting it in front of users. I am the ultimate buy one get one free; a true full stack developer with years of experience working with Rails and React. Let’s leverage my skill set to get your idea from in your head to on the web. Skills Great knowledge of Ruby. Experienced Next/React user. Sidekiq expert. Domain Modeling. CSS (SCSS, StyleComponents, Tailwind, Bootstrap, Whatever is clever). API’s and Integrations are my jam. I am very familiar with the JavaScript ecosystem including modern React and the current rise of hypermedia on, over, or around the wire. From LiveView in Phoenix, to Hotwire and HTMX, I’ve hosted projects in each. Legacy Code I have experience working with large media organizations that managed many forms of media from digital to printed magazine. Magazine systems are archaic, and very brittle. I refactored America’s Test Kitchen’s subscription service, allowing for greater resilience and capture. I am currently working for an enterprise grade e-commerce platform. We leverage Rails (Sidekiq) and process ~100M jobs a day.

I continuously strive for code quality and maintainability, while always balancing the business outcomes. I'm very comfortable with: - MiniTest & Rspec - Haml 🤗 - Hotwire - Stimulus - Turbo - Bootstrap - TailwindCSS & Tailwind UI - View Component - Caching - Queuing - Mentoring - AWS - PostgreSQL I believe in the monolith. <3

From the moment I wrote my first lines of code, I was drawn to the power of solving real-world problems through technology. Over the past 9+ years, I’ve honed my expertise in Ruby on Rails, Node.js, Python, Go, and React, building scalable, high-performance applications across FinTech, SaaS, and Healthcare industries. My passion lies in crafting robust backend systems, secure APIs, and seamless front-end experiences, all while optimizing for performance and maintainability. One of my proudest achievements was leading the migration of a monolithic Rails application to a microservices-based architecture using Go, Node.js, and GraphQL. By carefully refactoring services, implementing event-driven patterns with Kafka, and optimizing database queries, we cut response times by 60% and improved system reliability. This experience reinforced my belief that understanding the trade-offs of different technologies is key to building resilient applications. Beyond writing code, I thrive on mentoring engineers, leading technical discussions, and driving best practices in CI/CD, cloud-native development (AWS, Kubernetes, Terraform), and DevOps automation. I love tackling complex authentication challenges (OAuth, JWT, SAML) and designing secure, scalable APIs that empower businesses to move faster. At my core, I’m an engineer who bridges the gap between backend, frontend, and infrastructure—someone who doesn’t just build software but also optimizes it, secures it, and scales it. Whether it's refactoring legacy Rails applications, designing real-time systems with WebSockets, or deploying Go-based microservices, I bring a holistic, problem-solving mindset to every project.

Hello! I am a Rails and frontend developer who has worked at a variety of small companies and startups in various industries. This means I am a versatile problem solver who focuses on getting to the core of business problems before implementing solutions. In addition, I love working with people and am an engaged and helpful teammate. Recently, I have been working for a client on upgrading older Rails versions, implementing enhanced security mechanisms using devise and MFA, and of course building out features (e.g. billing). I have some strong AWS knowledge as well. I look forward to working with you!
