Hire Ruby on Rails developers

Results-driven Ruby on Rails developer with 7+ years of experience architecting and implementing scalable web applications. Expert in full-stack development across multiple frameworks and databases. Proven track record of optimizing application performance, implementing microservices architecture, and leading technical teams. Skilled in Agile methodologies, test-driven development, and cloud deployment strategies.

8+ Years of experience | Ruby on Rails specialist | Passionate about testing I've studied electronic engineering, specialty in computer science and sub specialty in physics. I am a self-taught full stack developer. I've learned to code on QBasic when I was a kid, at the end of the 90's, and I've been working in software development since 2014, most of the time working in Ruby on Rails, the sum adds 8+ years of experience in RoR. Since the first time I've started working with Rails I've worked following a TDD approach. My experience tells me that's the best way to avoid bugs. I've used RSpec all along my journey. My latest discovery is the best way to enrich my vocabulary in any programming language is by reading other people's code. That's the reason why I'm hunting issues in github, I've made several contributions to many different open source projects. My last PR is a fix for RSpec::Support::Differ class: I've found a bug when you compare two different hash objects and the expected value contains an "anything" fuzzy matcher, it adds noise to the output of the differ. My PR fixes that issue: https://github.com/rspec/rspec-support/pull/599 I have noticed the web is always consuming more and more memory ram. That's the reason why I've focused my efforts on my previous jobs to optimize slow web pages and optimize as much SQL as I can. I helped my last client to reduce in half the memory ram consumption measured on his Heroku metrics. These optimizations helped him to save money on Heroku. I am learning Rust and I have built many tools like rg_explorer to help me find what I need in big projects. I want to become proficient in Rust because I have hope in the future WASM may become something common in webapps, because I think that may be a good candidate to reduce the amount of memory ram consumed by web browsers. I am a versatile software engineer because I've used many programming languages in the past: Python, Rust, Node.js (including React.js and Vue.js). I have found many of the activities mentioned above are really boring for many people. It's odd that I enjoy doing them so much. That's why I think I like to do boring stuff...

Hi …. I’m Charlie. I am a Fractional CTO and Senior Ruby on Rails Engineer with 10+ years experience of building and scaling companies. I am equally comfortable discussing high-level strategic leadership or low-level technical problems. I have worked in, started and led multiple companies. Likewise, I have created, developed and maintained multiple web platforms. I recently led a major technological transformation at a group of companies, which is responsible for administering approximately 750 pension schemes. With £250M+ of assets under administration, 1,000+ clients and 30+ members of staff, it was always going to be a big challenge. When you also consider that almost everything was being done via email and phone calls, with 30+ disparate systems being used behind the scenes, the challenge went to a whole new level of complexity. I have written a number of articles about my experience and the key lessons learned.

I'm Aditya Jain, a backend engineer with over 7 years of experience, primarily building scalable, secure applications in Ruby on Rails. My journey began in electrical engineering, but I quickly pivoted into software development when I realized how much I enjoyed solving logical problems and bringing ideas to life through code. Rails, with its elegance and convention-over-configuration philosophy, instantly clicked with me—and I never looked back. One of my recent milestones was leading the architecture revamp of a high-traffic Rails-based payments system, optimizing performance under load and ensuring PCI compliance. This not only improved p95 latency by 45% but also reinforced my belief that solid engineering is about thoughtful design, not just writing code that works. What sets me apart is my ability to blend technical depth with business understanding. I don’t just deliver features—I ask why they matter, who they impact, and how we can deliver them better. I’ve led small teams, handled enterprise client integrations, and even driven analytics efforts using tools like ClickHouse. I also enjoy mentoring junior developers and fostering a clean, test-driven development culture. I’m passionate about creating systems that are not only efficient but also maintainable. Whether it's simplifying complex APIs, optimizing background jobs, or managing stakeholder expectations, I thrive in roles where I can be both a builder and a problem-solver.

Hi! I’m a full-stack developer who loves turning ideas into real, working products. I focus on writing clean, scalable code and enjoy solving complex backend logic. With over 2 years of hands-on experience, I’ve built and maintained full end-to-end systems handling lakhs of users and large volumes of data. Always curious, always learning—especially around system design, performance, and clean architecture. I started with Ruby on Rails for its simplicity and speed—and stayed for the powerful conventions. I’ve shipped production apps that power critical features used by millions, tackled tough refactors, optimized slow queries, and integrated real-time features using Redis and WebSocket.

I am currently a full time full stack engineer and team lead for one of the largest Out-Of-Home advertising companies in the country. I am a graduate of Flatiron School in NYC (2016).

My name is Jason Fleetwood-Boldt. My specialization is in automated testing. With codebases tested using automated testing, the engineers write the tests as part of writing the code itself. Automated testing enables solid agile practices like iteration and refactoring with confidence. This is an essential distinction from no-test waterfall development. With untested software and waterfall practices, the developers are constantly afraid of improving any existing code (paying down code debt) because it might break existing functionality. With automated tested development, both QA (quality assurance) and Product Acceptance are still essential. However, the test suite dramatically reduces the need for regression testing. We know that we have covered existing functionality by the tests we already wrote. For more information, please see my dev shop: Helios Dev Shop.
