Hire principal / staff freelance Ruby on Rails developers in United States

My most recent adventure in Rails involved building a real-time visualization feature, powered by Rails 7 and Hotwire technology, for a remarkable number of concurrent consumers. That project proved the productivity and low maintenance burden of applications built with Rails 7, AnyCable, Turbo, Tailwind, and Stimulus. I have experience in all areas of full-stack application development. I have used Terraform to create Kubernetes clusters in the Google Cloud Platform, built data pipelines with Kafka and PostgreSQL, and, of course, created and maintained production Rails-based applications from Rails 2 to 7. I currently build web-based applications with NestJS (Node) and React via Typescript. I am particularly proud at how quickly I am able to adapt to different paradigms and techniques. Take a look at my Github, I also have experience in Elixir and the Phoenix framework. I’m learning Swift; all to say that I’m always eager to improve my craft through any type of project.

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.

Rails architect with UX fluency, blending 20+ years of technical mastery with design thinking. Specializing in microservices, AI, and data platforms, I build developer-first solutions that scale.

I’m a product-minded developer who builds with the business’s needs front of mind. Ruby on Rails is my tool of choice because it’s the fastest way to turn ideas into impact. Its opinionated structure enables consistent delivery and makes it easier to scale teams without reinventing the wheel. Over the past decade, I’ve led and contributed to projects that not only ship but drive significant business impact In one internal platform modernization project, leadership projected needing 16 full time employees after the rebuild. Four years later, the same team of four was still using the software productively saving the company 12 full time employees. I also look beyond the technical tasks to spot leveraged opportunities. On a recent project, I identified a low-priority feature that, if built more robustly upfront, could unlock internal productivity. That decision now saves every employee 30 minutes a day, which results in thousands of hours a year saved. I thrive when building internal platforms, business efficiency, and moving fast to get the business impact as quickly as possible.

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.

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'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.

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.
