Hire senior Ruby on Rails developers

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.

Ruby on Rails. 5+ Years. Built and scaled web solutions with Ruby on Rails for a startup (team of 3). Tackled senior-level tasks: optimized legacy code, designed APIs under tight deadlines. Expanded into cloud infrastructure: deployed servers on AWS, Google Cloud, Digital Ocean, and Heroku. Fluent in English & Portuguese, conversational Spanish. As a Ruby on Rails developer with five years of experience, I thrive on turning ideas into seamless, user-focused web solutions. My journey kicked off with a curiosity about what powers the digital world—a spark that’s since grown into a deep passion for crafting reliable, impactful software. At a startup, I worked with a tight-knit team of three, diving into senior-level challenges head-on. From optimizing tangled legacy codebases to designing scalable APIs under tight deadlines, those high-stakes tasks sharpened my ability to adapt, innovate, and deliver, no matter the complexity. I’m more than a coder—I’m a problem solver who brings enthusiasm and precision to the table. A recent milestone I’m proud of? Expanding into cloud infrastructure. I’ve been spinning up servers on AWS, Google Cloud, Digital Ocean, and Heroku, pushing my skills beyond app development into architecting robust, high-performance environments. This rare mix of full-stack expertise and DevOps know-how lets me offer end-to-end solutions that stand out in today’s fast-paced tech landscape. What makes me unique? I pair a rock-solid Ruby on Rails foundation with an insatiable drive to learn and a talent for connecting the dots. Fluent in English and Portuguese, with conversational Spanish, I’m built to collaborate across diverse teams and cultures. I’m eager to join innovative companies where I can blend my skills with cutting-edge projects, grow alongside brilliant peers, and tackle challenges others might miss. Whether it’s unraveling backend puzzles or deploying cloud-native systems, I’m the developer who gets it done—and then pushes it further.

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)

Senior software developer with over 22 years of experience building mobile and web apps, with over 12 years building on Rails. To me Rails is more than just a software framework, it's also a development philosophy. The Rails principles like convention over configuration, separation of concerns, keeping it simple, and don't repeat yourself, help create cleaner and more scaleable projects. I'm big advocate for self documenting code, not reinventing the wheel, keeping things consistent, and designing with constraints, always striving for writing very readable and maintainable code. I also like to follow best practises including using trusted gems like Devise for authentication and Cancancan for authorization, and as well as new frameworks like Stimulus, Hotwire and StimulusReflex.

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.
