Hire principal / staff Ruby on Rails developers

Developer origin story I've always had a love for this craft. I was introduced to computers through my dad (works at Google). I went on throughout High School and college building robots, then teaching others how to build and program robots, and building my own self hosted networks and distro-hopping linux flavors Passions I believe that an expert developer is a unique asset to a company as they can drastically change its course. I like working with startups, and I have 15 years of tips, tricks, techniques, strategies from a technical perspective as well as an business/operational perspective. How I can help you I am a Rails and PostgreSQL expert. That means that I am very familiar doing things the rails way. There are things that you can only learn from being in a career for so fifteen years. I call it hidden knowledge. At some point you develop a sixth sense for when and how deep to test, which refactors are necessary, a set of practices for handling ActiveRecord associations. Unique skills that make me awesome I've written custom PostgreSQL extensions You'll notice with me that I am very quick on the keyboard, and between the well placed lame jokes, combined surgically precise problem solving, I have consistently told me that I am a pleasure to work with. Core Skills Ruby/Ruby on Rails ❤️ PostgreSQL ❤️ API ❤️ Turbo/HotWire ViewComponent TailwindCSS RSpec GoodJob/Sidekiq ActiveRecord/Sequel Documentation/Training Javascript Business Intelligence Analytics Mentoring Startups I built and sold directmailer.io, a direct mailer marketing platform that provides modern marketing conveniences to a legacy channel.

I was hired to build the core infrastructure for floridahomesteadcheck.com, a property tax analysis tool that guarantees the lowest property taxes for Florida residents. You! You have an idea worth building

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.

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.

I work as a Fractional CTO, Ruby on Rails Developer, and Data Engineer. As a Fractional CTO, I practice immersive leadership—I engage with every layer of the business. I work alongside developers, directly contributing code to the project. I work with founders to create accurate timelines and accelerate time to market, and with vendors to ensure that the business and technology strategies are aligned. As a Ruby on Rails Developer, I focus on scaling legacy Rails applications and optimizing PostgreSQL databases. I especially enjoy working with modern Rails and developed httpscout.io, a website uptime monitoring service, using Rails 7. As a Data Engineer, I work with Python and the "PyData" stack, particularly focusing on e-commerce time series data. I prefer leveraging existing technology and using open-source solutions wherever possible. My approach is iterative, and I work closely with stakeholders to ensure we build precisely what’s necessary to drive key business objectives. I am always open to engaging in interesting projects.

I'm a seasoned Ruby on Rails developer with a track record of scaling web applications to over 1 million users. I have 7+ years of experience in Rails. I have worked with products of various scales from building MVP to scaling applications in the growth stage.
