Hire senior Ruby on Rails developers in United States

With 5+ years of Rails experience, I come with a wide range of experiences and love to delve into new projects. I am working on a variety of pure Rails apps, leveraging the power of Hotwire and TailwindCSS on the front end. My personal project is https://anecdot.co, a platform for recording, preserving, and sharing life stories.

Hi, I'm Mike! I've spent the last decade working on Rails at scale--from high-traffic APIs to complex backend systems. Beyond Rails, I've built React frontends within Rails applications, shipped React Native apps, and developed native iOS applications. What I bring to teams: * Code quality at scale - I implement systems (RuboCop, ESLint, automated testing) that keep large codebases maintainable as teams grow * Performance-first mindset - I use observability and metrics to identify bottlenecks before they become problems * Deep debugging skills - Whether it's a memory leak in production or a race condition in tests, I'll dig in until we find the root cause Recent technical interests: Hotwire/Turbo, LLMs, agents, and contributing to open source.

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.

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.

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.
