Hire principal / staff Ruby on Rails developers in United States

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"

💭 Do you have an idea that makes sense in theory, but you haven't gotten it beyond that point? An existing team that could use some direction? Perhaps a product that you've gotten to market, but you're finding it harder to add more and more customized features and keep it performing the way it should? 👋 For a little over a decade now, I've been building clean, maintainable, applications for everything from cyber security, high traffic (millions of transactions per day), credit products, custom learning platforms, to custom storefronts. 🤖 I take a pragmatic approach to development, I'll hear you out, ask some pointed questions along the way, give targeted feedback, and rinse and repeat until we've got a clear vision for your product. You'll be able to give feedback on quick builds that are put together in days / weeks rather than months. This process is called prototyping. 🏆 Prototypes are great, but they won't take into account all the nuances needed for a product to start serving customers, so from there we'll have a conversation about what your "must haves" are in order to get a product in front of customers. Anything that you'd like but isn't a "must" will be outside the scope. This step is where we build an MVP (minimum viable product). The goal here is to get your product to market as fast as possible. Paying customers are the best source of feedback you can get, but we need an MVP to get them in the system. From there we work on the features that you and your customers want most. I'll always give you straight talk on what options you have for various features, and steer you toward the most practical technology choices to handle the functionality you want, while also working within your budget. Core Services build a prototype or MVP jump into an existing application and work through a hard to build feature, or difficult bug improve the performance of your existing application improve your authentication layer (add popular authentication providers and protocols) improve your application security (evaluate and fix security holes, work through security questionnaires your clients send you) begin accepting payments in your application make your application mobile friendly (either using responsive / progressive design techniques or with a full fledged mobile app) give feedback on and improve your existing design Have an existing product? I specialize in performance enhancements to a product that feels a bit sluggish, as well as ensuring you can handle an expected jump in traffic pragmatic AI architecture. If you're not sure where to get started, I've already built out several multi-agent AI driven tool sets that go beyond having a context driven interaction with customers, and instead allow customers to handle complex tasks through text messaging and voice. Rails upgrades team augmentation

Looking for new clients who are trying to solve real pain points. If your systems aren't organized and efficient, I'd love to help you improve them. I run a small team and whether your project is big or small, we can help. We'll work together to break your project down into manageable pieces. You'll always know where we are in the process and be able to steer the ship as priorities change, through regular check-in meetings to review progress.

In the mid 90s, my mom's HP Pavilion was struck by lightning. Luckily, I accidentally saved a few Dragonball Z websites. Back then, you could view the source code of almost any website and copy everything there to recreate them through your browser. This is what led me to my love for web development. Hi, I'm Chris. I've been in web development professionally for over a decade. Those saved websites opened up a door into a world of problem-solving that I absolutely fell in love with. I've built everything from real-time user tracking to a key inventory management system to an events timeline to countless APIs and integrations, and somewhere in between all of those features, I found a knack for UX and UI.

I'm a Full Stack Software Engineer with 9+ years of professional experience. While most of my experience has been in Ruby on Rails and Javascript, I've also shipped production-level projects in many other languages including Elixir, C#, Java, Python, and more! A few projects that I'm most proud of include: - Built a live feed that streamed 10,000+ Cryptocurrency prices per second to trading algorithms. - Created an open-source Ruby gem to perform technical analysis on stock price data sets. - Improve the performance and response time of monolithic Rails projects by 80%+ using edge caching. While it's not technically a project, I'm also proud of my experience in mentoring junior engineers. Hobbies and interests - Golf - Cars/motorsports - Dogs (I'm a fur father to a 4-year-old, rescued Catahoula mix)

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.

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.

Hello! I’ve been a professional Software Engineer for 10+ years and started working with Rails in 2014. I have a lot of experience working for early stage startups and wearing many hats. Most recently, as the first full-time employee and VP of Engineering, I was instrumental in the growth of a startup to over $10M ARR in 5 years with an engineering team of two. This led to an acquisition where I served as the point of contact for the technical due diligence process. I’m detail-oriented and value pragmatism, communication, and simplicity. I’m currently open to part-time and full-time consulting opportunities. How I can help (a non-inclusive list): Feature development Architecture review & planning Performance monitoring & improvements Technical interviews & evaluation Ruby on Rails & Database performance Code review Code refactoring with recorded Loom videos to show why Please reach out if you’re interested in working together!

I help Rails developers build web-powered iOS and Android apps with Hotwire Native. Hotwire Native enables teams to build high-fidelity hybrid apps by rendering HTML inside of native navigation. It means your team can reuse mobile web views across platforms. Create your views once, in Ruby + HTML, and render them on mobile web and in the iOS app. And when you need even more fine-grained control, you can drop down to native UIKit and Swift UI to build fully native views. This flexibility lets you produce large apps with small teams. Achieve baseline HTML coverage for free. Upgrade to native views as needed. Here's how I can help: Bridge the gap between your Rails app and iOS by implementing the necessary Ruby and Swift + Kotlin code. Level up your team's Hotwire Native + Hotwire skills with pair programming and workshops. Offer advisory guidance on best practices in the hybrid space from my 5+ years building Hotwire Native apps. I'm also the solo-founder of RailsDevs, the site you're using right now.

TLDR- I know Rails, let’s build together. I understand that the most important part of any project is getting it in front of users. I am the ultimate buy one get one free; a true full stack developer with years of experience working with Rails and React. Let’s leverage my skill set to get your idea from in your head to on the web. Skills Great knowledge of Ruby. Experienced Next/React user. Sidekiq expert. Domain Modeling. CSS (SCSS, StyleComponents, Tailwind, Bootstrap, Whatever is clever). API’s and Integrations are my jam. I am very familiar with the JavaScript ecosystem including modern React and the current rise of hypermedia on, over, or around the wire. From LiveView in Phoenix, to Hotwire and HTMX, I’ve hosted projects in each. Legacy Code I have experience working with large media organizations that managed many forms of media from digital to printed magazine. Magazine systems are archaic, and very brittle. I refactored America’s Test Kitchen’s subscription service, allowing for greater resilience and capture. I am currently working for an enterprise grade e-commerce platform. We leverage Rails (Sidekiq) and process ~100M jobs a day.
