The reverse job board for Rails developers

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.

Did a internship, but im looking to become a good ruby on rails developer. Like to work with javascript frameworks and with rails.

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).

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 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.

Hello, I'm Jonathan. I like solving problems—often with code. I'm a full-stack engineer with 7+ years of experience building scalable web applications, primarily with Ruby on Rails. I thrive in environments where I can own high-visibility projects, collaborate across functions, and move fluidly between strategy and execution. I'm also very comfortable in asynchronous workflows and product-driven teams. I've built integrations with external APIs, including payment processors and Visa, and I've led projects from idea to launch. Mentorship is part of my rhythm—whether through pair programming or thoughtful code reviews. Lately, I’ve been working on a personal project: an AI-powered productivity app designed to help users set goals, track tasks, and build momentum. I care about clean architecture, thoughtful collaboration, and building tools people actually enjoy using.
