Hire senior Ruby on Rails developers in United States

12 years of experience building and launching successful B2B SaaS products with Ruby on Rails. I'm a passionate engineering and product leader. I fell in love with the Hotwire stack early and run a popular blog filled with tutorials on how to use Stimulus, Turbo, and friends to build modern Ruby on Rails applications. My expertise is in helping early-stage companies figure out what to build and how to structure their teams and products for growth, and I can rapidly ship plenty of Rails code for you in the process. I have experience working on production applications from Rails 3 to Rails 8 and deep knowledge of Bullet Train and Jumpstart Pro applications. I strongly advocate for a full-stack Rails experience whenever possible.

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. If you’re interested in working together or just want to talk shop, feel free to reach out.

I am currently a full time full stack engineer and team lead for one of the largest Out-Of-Home advertising companies in the country. I am a graduate of Flatiron School in NYC (2016).

My name is Jason Fleetwood-Boldt. My specialization is in automated testing. With codebases tested using automated testing, the engineers write the tests as part of writing the code itself. Automated testing enables solid agile practices like iteration and refactoring with confidence. This is an essential distinction from no-test waterfall development. With untested software and waterfall practices, the developers are constantly afraid of improving any existing code (paying down code debt) because it might break existing functionality. With automated tested development, both QA (quality assurance) and Product Acceptance are still essential. However, the test suite dramatically reduces the need for regression testing. We know that we have covered existing functionality by the tests we already wrote. For more information, please see my dev shop: Helios Dev Shop.

I've been hooked to Ruby and Rails ever since attending a Pragmatic Studio training in 2008. Recently discovering new joy in writing Rails apps that generate HTML on the server as opposed to JSON sent to a client javascript app. Love helping other developers find their way along the never ending journey of software development.

A passionate software engineer with the growth mindset of an entrepreneur. I have experience building web applications with well-known frameworks, including Ruby on Rails. I've been lucky enough to build integrations with many third-party API's including: Stripe, Zendesk, Facebook, Airbnb, Expedia, MailChimp, PayPal, Twilio, Segment, Twitter, Booking.com, Securities and Exchange Commission, and more. I have a high bias for action and like to move quickly and iterate. I'm a patient communicator and introvert. I'm a hacker at heart and like finding creative ways to push business to the next level.

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!
