Hire Ruby on Rails developers

I am a career-changer that has always found ways to use my coding skills to enhance my value. I am seeking to transition into software development full time. As a career "pivot," I have a strong and reliable work history. I have been the director of a non-profit subsidiary, managed the development of a Salesforce platform for a program providing college education to incarcerated and formerly incarcerated students (700+ students in six locations), launched a temporary supportive housing program for formerly incarcerated college students working towards completion of their degrees, and previously worked as a paralegal at law firms defending doctors and hospitals in healthcare litigation. All of this built upon a degree in business with a concentration in mathematics. As a developer, I attended a coding boot camp focused on Ruby, Rails, and JavaScript. I have a portfolio of student projects to show for it, but most of my recent coding has focused around open source contributions to projects like Dry-rb and Hanami, including a major refactor of the Hanami Router library. I am insatiably curious and love to learn. I am an excellent communicator, with experience writing documentation, delivering talks, and teaching seminars. I believe that learning, teaching, and collaboration are the three founts of productivity and innovation. I would love to speak with you about how I can contribute to your project and team!

Rails architect with UX fluency, blending 20+ years of technical mastery with design thinking. Specializing in microservices, AI, and data platforms, I build developer-first solutions that scale.

I'm a Software Craftsman with 20+ years of experience building from web applications, to ETL, BI, data mining solutions and even some desktop applications. I prefer to work on the web but away from the browser. I enjoy refactoring and optimization workloads and I love to explore new technologies. I have a clear preference towards Ruby but I can work in any technology - throw me some Javascript, Java, C#, Clojure and I'll pull on all my experience to do an outstanding job.

Who am I? I am Tom Dallimore, a developer from the UK. I currently work as a freelance Rails & React Developer, my 2 favourite frameworks that I thoroughly enjoy using (so far!). Additionally, in my spare time, I am managing a Gen AI platform I launched late last year called Fetch Hive(fetchhive.com) and a typeform alternative form builder called JotJab(jotjab.com). But before we go any further, let’s get to my story and why I think we are a great fit for each other. My story Let’s get started. I am a 35 year old developer who has been developing all kinds of applications and software for the past 17 years. When I started software development (when I was about 16 years old) I learned the basics of HTML, CSS and a little bit of Javascript. After that I moved onto PHP and C# for a small time but then stumbled upon Rails. I became intrigued, since when did writing code become so fun and fast? At the time I was working at Dyson as a C# developer, but in the evenings and mornings I was building my own little applications - a lot of fun. I eventually settled on creating an ecommerce app (yeah, I didn’t know at the time how much work that would be), which eventually grew into Trado - an open source e-commerce application. Fast forward a year or so and I was offered a job to work at an agency in Beijing. It was a contract based job which was primarily on upgrading, managing and debugging Rails applications, certainly an interesting experience. From there I decided I wanted to dive back into the world of freelance. I helped several companies launch apps using a mixture of React and Rails, including an online store for PPE supplies, a charity donation web + mobile app and an app for the Shopify Partners ecosystem. Why me? I love to experiment and build tools which help people’s everyday lives be more productive and fun! I would say the most rewarding part of being a developer is seeing apps I helped create become a rewarding tool for the user. I’m not just a developer Over the years I’ve worked on projects with teams and on my own. The latter meant I needed to take up other responsibilities to ensure the delivery of a product. These included tasks such as, server management, UX/Product design, graphic design (my father ran a graphic design agency) and from time to time marketing/branding. Guess you could call it a swiss army knife of skills! Side projects As I previously mentioned, since a young age I’ve always enjoyed tinkering with stuff in my free time. The most recent project is Fetch Hive. I've been working with a few companies in the past couple of years which want to utilize AI in the business, but quickly became tired of the constant back and forth between developers and project managers. Building prompts, agents and integrating data sources like Google, Website Scraping and Exa just became slow and cumbersome as it was all in the code. So I built a complete Gen AI platform, an all in-one workspace for engineers, product managers, and non-tech teams to explore LLM tools. It runs using Rails, Rust, React, TailwindCSS, Shadcn and Vite, all hosted on Hetzner and Cloudflare using the amazing Dokku engine (seriously, the best open source PaaS out there!). Another project I also built last year is JotJab. At the time I was using Typeform to create forms for communicating with audiences on the web, but I couldn’t stomach their high pricing. So I built an alternative product which is accessible to businesses of all sizes without breaking the bank. Staying in touch • I keep updated with the OSS community on Github • I follow a lot on Twitter and actively share daily • I follow a few YouTubers. • And I dabble in Reddit, from time to time. Soft skills I like to talk, throw ideas around, and have long conversations about certain topics. I love to experiment with “outside the box” ideas. I do have opinions, I like to discuss and have a conversation about my opinions, but I also love to change and adapt my opinions based on new information. After hours • I’m always keen to learn new technologies, currently experimenting with Go and Flutter • I have a passion for photography and videographer, mostly when taking trips into the countryside • I do enjoy watching a good series now and again, like Shogun There is a lot more I would like to talk about, but I hope I’ve already convinced you enough to start a conversation. I look forward to hearing from you.

What Makes Me Different: What distinguishes me as an engineer is my unique journey through financial systems architecture combined with a relentless focus on observability and quality. While most developers build features, I build confidence - creating systems where you not only know when something breaks, but why it broke and how to fix it. My engineering approach was forged in the high-stakes environment of processing $100M+ daily financial transactions, where 99.999% uptime wasn't a goal but a requirement. This experience taught me that truly resilient systems aren't just well-architected; they're well-observed, well-tested, and well-documented. I've transformed chaotic codebases into comprehensible systems by establishing monitoring standards, comprehensive test suites, and clear documentation that empowers entire engineering teams. Where I truly excel is bridging the gap between complex technical implementations and business value. While many engineers can build impressive systems, I create sustainable architectures that solve real business problems. At a major top 4 US Financial corporation, I didn't just modernize a Rails platform; I enabled new financial products that directly increased revenue while reducing fraud by 35%. This business-focused mindset means I approach engineering challenges not just asking "how do we build this?" but "why are we building this and how will it create value?" My passion for mentorship has led me to develop a framework for growing junior engineers that has consistently helped them advance to senior roles in half the typical time. By creating structured growth plans combined with hands-on pairing sessions focused on system design principles, I've helped eight engineers dramatically accelerate their careers. I believe that building great engineers is as important as building great software - both are essential for long-term success. What truly sets me apart is my ability to transform complexity into clarity. Whether it's untangling a legacy codebase, explaining technical constraints to product teams, or documenting intricate system interactions, I excel at making the complicated understandable. This talent for simplification doesn't just make me a better engineer; it makes everyone around me more effective.

Hi, I have 3 years and 10 months of experience working with Ruby on Rails, PostgreSQL, and Postman. I have hands-on experience deploying applications across staging, UAT, and production environments. I'm available to join immediately and thrive in roles that offer new challenges and opportunities to collaborate with others. I'm flexible with both remote and on-site work environments.

With 10+ years of Ruby on Rails expertise, I don’t just build applications—I engineer scalable, maintainable systems that solve real business problems. My journey began as a curious developer tinkering with Rails, and over the years, I’ve evolved into a problem-solver who bridges technical complexity with business value. One of my proudest achievements was optimizing multi-tenant database migrations by 75%, introducing rigorous security checks, automated code analysis, and comprehensive test coverage—ensuring reliability at scale. I’ve also turbocharged report generation by refining ActiveRecord queries and leveraging PostgreSQL optimizations, slashing load times while maintaining data integrity. Beyond coding, I thrive on efficiency and reusability. When integrating third-party APIs, I don’t just glue them together—I built my own Ruby gem to encapsulate logic, making future integrations faster and cleaner. Staying ahead of the curve is second nature: I run a weekly tech newsletter to keep my team (and myself) updated on Rails, Hotwire, and PostgreSQL advancements, ensuring we’re always leveraging the best tools. What truly sets me apart is my blend of deep technical skill and strategic thinking. I don’t just write code—I architect solutions that are secure, performant, and maintainable, while mentoring teams to raise the bar collectively. If you need a developer who ships high-quality software and elevates those around them, let’s talk. 🚀
