Hire Ruby on Rails developers

With solid experience in Ruby on Rails, I specialize in building scalable web applications, ensuring high-performance backend systems, and optimizing SQL databases for efficiency. Proficient in TypeScript and React, I craft dynamic, maintainable frontend components while integrating robust backend services. My development approach is anchored in Test-Driven Development (TDD), fostering reliable and efficient codebases. Passionate about clean architecture and automation, I continuously explore emerging technologies to enhance development workflows.

I'm Matt Lins, and I have an extensive 18-year background in web development, specializing in Ruby on Rails. I've applied my craft to build scalable E-commerce, Healthcare, Proptech, and iGaming sites. Along the way, I've led engineering teams to achieve company exits, and in doing so, I've learned that the most sustainable code and tech solutions emerge from the pursuit of simplicity. I advocate for simplicity in development - a belief deeply rooted in the principles of Gall's Law, which I see as essential for creating solutions that focus more on business value than technical complexity.

Who am I? I am Tom Dallimore, a developer originally from the UK but now living in SEA. 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 business 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.

My journey as a developer started when I was selected to build internal software for my college to track exchange students. With little more than curiosity and determination, I dove into Ruby on Rails—and I haven’t looked back since. Since then, I’ve worked on meaningful, real-world Rails applications like CancerCare, where I helped modernize a legacy codebase for a national nonprofit. I improved performance, redesigned the UI, fixed long-standing bugs, and restored core features like Elasticsearch—all while learning how to work within the constraints of an active production system that people rely on daily. What makes me unique is that I’m not just focused on writing code—I care about why the product exists, who it's serving, and how to build something that lasts. I'm passionate about clear communication, thoughtful refactoring, and learning new tools that help me do better work. For example, I’ve recently built my own project, Shoe Sensei, which uses Rails, Hotwire, Stimulus, and a full testing suite to provide a fast, dynamic user experience. I approach development with curiosity and care. I like understanding how things work under the hood and making small, meaningful improvements that add up over time.

Hi, I'm Mike. Over my career, I've worked at a variety of companies of different sizes and problem domains. I've seen a lot of what works and what doesn't, so I think I can provide insight on processes and approaches to common problems teams run into. I do my best work when given a goal. I like to focus on the product first and the rest can always be improved upon later. I'm big on testing and I use TDD often. TDD helps me move quickly. As the first hire at a fintech startup: * Built and launched the initial version of the product. * Interviewed candidates for both technical and behavioral assessments. * Recognized as employee of the month in Feb '23 for embracing ownership. I came up with a way to reduce the company's risk. * Recognized as employee of the month in Jun '23 for embracing simplicity. I helped launch a large feature in a short amount by working closely with product to reduce the scope. * Built, maintained, and improved the core product that has led to a Series A.
