Hire c-level Ruby on Rails developers in United States

Seasoned code wrangler with over a decade in Ruby on Rails and a past life as a social worker and policy researcher. I've got a knack for translating geek speak for humans and wrangling stakeholder needs into delighted users and maintainable code. Looking to land in a place where code meets impact. Full stack developer that has spent over a decade in the Ruby/Rails ecosystem. I lean ops to backend, but I can get in there and wrangle JS components and CSS if need be. I often wear at least a little bit of a product manager hat, have been a team lead on large projects, and I even try to remember to write documentation and technical briefs. I'm longwinded in slack, shy in person, didactic and friendly in code reviews, and occasionally down a rabbithole. Loves: Wrangling weird bugs and annoying APIs, refactoring, clear code (for the humans) and good tests (for the robots), figuring out the best places to deliver maximum impact and shipping quickly, teaching myself new things, compassionate communication and collaboration with multiple stockholders, making weird things happen in the CI pipeline Special superpowers: T-shaped generalist that still geeks out on learning new things, sniffing out something that isn't a problem yet but definitely will be (and I don't mean premature optimization), care a lot about readable code. Worked as a social worker for a decade, there's more soft skills than people might think in getting software out the door. Not so loves: JS in general, jerks, arrogance, watching junior developers not get the support they need and thinking it is their fault, refreshing staging for an hour wondering why my debugger isn't getting hit. -- Have worked in startups at all stages of their life cycle as both an introverted grumpy solo developer and team leader, helped make product decisions, mentored other developers, deleted prod a few times, etc. I chafe a bit at schedules, but occasionally I'll figure out a big that would have been a big problem in the future at 3am and just fix it. Love fixing those things. I can meeting during normal human hours though. -- Open to short and long term contracts and FTE for the right fit. Prefer chill flat organizations where everyone likes and respects each other and just gets stuff done. I've shipped features faster at those organizations than any that were focused on relentless hustle. -- Tell me why you believe in your tech and I'll tell you about one of my weird side projects like a Led Zeppelin button or a confessional that floats in the air. -- Have PhD level statistics classes buried in my brain somewhere, know my way around python and some data analysis, have built ETL pipelines - if it has to be done, I'll try to figure out a way to get it done. And the longer you hang around this world, you realize the most important programming language is being able to talk to people in kind and useful ways. -- Senior enough to know that sometimes it's the code you don't write that solves the problem ;) Junior enough to still get excited every time I make LEDs blink with magic words.

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've been a software engineer and leader for 18 years, with a focus on Ruby on Rails and full-stack development for the last 13. I’ve lead teams of 30+ as a staff and Principal engineer, and as a people manager. I’m an expert in web, mobile, api, service-oriented and micro-services architectures, data pipelines, AI and voice-enabled applications. In addition to Rails, I’m also an expert in React, React Native and JavaScript. I’ve recently owned projects in Python, Django, Typescript, Swift for IOS, Kotlin for Android, and can pick up any language/ framework with a few weeks practice. I offer hands-on development, team leadership, code reviews, team training and up-leveling, as well as UI/UX design and research, project and product management, strategic planning and roadmapping, and compliance for HIPPA and SOC. I’m available for hourly contact rates, or monthly support plans.

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.

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.

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.

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 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.

Practicing engineer for 30 years. Web Dev for the past 15 with Rails. Also: C, C++, C#, Ruby. linux command-line, Python, database architectures, microservices, team manamagent. I love to help teams in a variety of ways: Pairing/mentoring with junior developers to help them level-up Workshops for teams to increase their classic Computer Science knowledge Working with C-Suite executives on strategic planning, resources allocation, and technical roadmaps I actively teach in the Masters Program for Computer Science at the University of Chicago. I also run Software for Research, a platform for clinical research at academic institutions. I have a long-time hobby in the Learning Sciences and love to help teams "learn how to learn"
