Hire freelance Ruby on Rails developers in United States

I am a Product Engineer focusing on full-stack applications and highly scalable backend systems. I am interested in everything web and the opportunity to learn new languages/techniques to solve tasks. I have built banks and might build more. I love everything related to money transactions and thrive in environments where failure is not an option. I am super excited about Ruby on Rails, everything that has changed since version 7, and what is coming in version 8.

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 help Products thrive through user-centered design, and the ability to wear multiple hats. Using Ruby on Rails as my foundation, I've built, deployed, and maintained Products that leverage (React, React Native, Electron, and more recently, Hotwire) as a Solo Developer and UX Designer. (Need help migrating some React code to Hotwire? I can help!) With a background in UX design and 10 years of invaluable lessons, I've developed a keen focus on: Shipping features quickly without big designs upfront. Spotting areas of technical debt early. Enhancing and simplifying UI by minimizing its required interactions. Writing tests that focus on what matters. Recent things that i'm proud of: A small frontend input validations library I made called 'stimulus-inline-input-validations' was included in the Hotwire weekly newsletter. My open source contributions to this very site! (RailsDevs) My article (Using Custom Turbo Actions with StimulusJS) was included in the Short Ruby Newsletter

Throughout my engineering career I have been focused on shipping high quality Ruby on Rails web applications for startups, SMBs, and Enterprise clients through deep collaboration with internal and external team members and relevant parties. I have extensive experience with Ruby, Rails, Hotwire/Turbo/Stimulus, JavaScript, React, automated testing, DevOps/Infrastructure, mentorship, and optimizing the developer experience. I am deeply interested in building web applications that deliver high value both from a technical and a business perspective. In addition to complex, well-tested, and high quality RoR development, I have experience implementing CI/CD workflows, DevOps, external integrations, ETL pipelines, and complex feature requests that require robust collaboration with stakeholders. I constantly seek opportunities to mentor engineers and to stretch my own knowledge and expertise.

👋🏻 ㅤI am a Full Stack Developer with 8+ years industry experience building web/mobile applications, also passionate about UX. I specialize in Ruby on Rails and JavaScript Frameworks (React & React Native).

Senior engineer with experience in both greenfield and legacy codebases. I believe that developer happiness and productivity are doubly linked and strive to optimize for both. I've been living the dream with code since I started at 12 years old. Collaborative, no-ego teams are my favorite to foster. Most recently I've been working in the real estate industry on a legacy monolith application with Hotwire and ViewComponents. I've worked successfully with both US and overseas development teams and know how to get the most out of them.

👋 Hello! I create art with various mediums; music, poetry, graphic design, and technology. Ruby on Rails is my go-to web development framework! 💪🏽 I like my Rails mono, Javascript and HTML vanilla, my stylesheets SCSS-y, and my Turbo Hotwired (as soon as I really learn Hotwire). As a self-taught, Full-Stack Developer with a deep understanding of the entire web development process, I love seeing ideas go from concept to products and services. We might be a bad fit if you're looking for a computer scientist. Sorry, mate.

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. Somehow, most days, I still like my IDE. 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 -> 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 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.

Hey there, I'm Michael! I've had titles such as CTO, VP of Engineering, and Lead Senior Engineer before. I have contributed about a dozen PRs too Rails and many more PRs to other gems in the Ruby and Rails ecosystem. Currently, I'm working a contract role as a Lead Software Engineer for a "big-tech" company as well as advising a few startups. I am open to new full-time and part-time opportunities so feel free to message me! I have experience with everything from software architecture, security engineering, database design, query optimization, and Rails performance improvements, as well as plenty of front-end development with everything from jQuery to React to now Turbo and Stimulus. In fact, despite my experience throughout the backend, I find front-end and ultimately "full-stack" product development to be the most fulfilling! Don't hesitate to reach out to see how we might work together.
