招聘 senior Ruby on Rails 开发者

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.

I am a software engineer with over two decades of expertise. Originating from France, I've been contributing to the tech scene in Japan since 2006. Fluent in French, English, and Japanese, adept at working both back-end and front-end development. Specialized in diverse technologies, including Ruby on Rails (since 2014), Golang, GraphQL. I have worked for businesses or organizations of all sizes. Notable roles include work as a freelancer for Red Bull Japan, Google APAC, Tokyo Art Beat. Eager to bring technical expertise, creativity, and dedication to new challenges and projects. I have been working remotely for more than 10 years.

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.

I am an independent developer and OSCP-certified penetration tester with more than a decade of experience with Rails. I can help you with anything security related: auditing, penetration testing, implementing security related features, incident response, etc. I also have extensive experience in performance optimization of Rails applications. If you want to lower your hosting costs and looking for someone to make your application's performance better, I am a good candidate to help you with that. I can also navigate my way around in legacy code, during my career I've worked with many applications that had a lot of technical debt, I can help to handle them.

I've been hooked to Ruby and Rails ever since attending a Pragmatic Studio training in 2008. Recently discovering new joy in writing Rails apps that generate HTML on the server as opposed to JSON sent to a client javascript app. Love helping other developers find their way along the never ending journey of software development.

I'm Veteran Full-Stack Ruby on Rails Developer with ReactJS expertise. Proficient in Hotwire, Turbo, Stimulus, JavaScript, AWS, Github, Heroku, and various other technologies. Skilled in self-management for independent projects and a collaborative team player. I have worked in different domains like healthcare, legal, security, construction, social media and others. I'm passionate about coding, especially in Ruby with the magic of Rails making things smooth sailing. I've built plenty of projects, and now I'm excited about combining Ruby on Rails with AI. I'm skilled with Git, RSpec, and handling databases. I also know my way around frontend tech like ReactJS and AngularJS, as well as integrating APIs. I've led small developer teams back home, using tools like GitHub, GitLab, Notion and Linear. I'm fluent in Gujarati, English, and Hindi, making communication a breeze. As a remote developer, I'm here to turn your ideas into reality. Whether it's working solo or coordinating a team, count me in to get the job done. I can provide a wide range of services that are designed to attract attention and cater to the most searched for needs. Here are some examples of the services I offer. -> Web application development -> Font-end UI/UX development -> Back-end REST APIs development -> Application deployments on cloud -> Version upgrades -> Technical lead for teams -> Application maintenance or support -> Technical consultation -> Project management -> Problem solving -> Small project to large (feature, enhancement, bug, issues)

I'm a full-stack developer passionate about building scalable, secure web applications that solve real-world problems. With a strong foundation in Python/Django and Ruby on Rails, I've delivered high-impact systems for government, logistics, and healthcare—most recently developing a secure logistics platform for Kenya’s Ministry of Defense. I’ve modernized legacy infrastructures using React, Node.js, and AWS, and contributed to AI research at Scale AI by refining code generated by large language models. I care deeply about clean code, performance, and delivering solutions that drive efficiency and growth. Let’s build something that matters.
