The reverse job board for Rails developers

Hi, I’m Rahul – a backend developer with a strong foundation in Ruby on Rails and a growing expertise in Node.js. I specialize in building and optimizing LMS platforms, working with complex domains like courses, learning paths, event sessions, assessments, and analytics. With a strong focus on performance optimization, I’ve worked closely with developers and CSM teams to solve real-world product challenges efficiently. Currently, I’m expanding my skill set by diving into Node.js and modern JavaScript tooling. I’ve worked with npm and global package management, and I’m actively exploring parallel processing and scalability solutions for high-performance applications. My passion for learning doesn’t stop there—I’m also deeply invested in data structures, algorithms, and object-oriented design, constantly solving LeetCode problems to sharpen my problem-solving skills. Beyond web development, I’m interested in system design and have been working on a news aggregator project to improve my ability to architect scalable applications. Looking ahead, I’m exploring low-level programming languages to stay ahead in the ever-evolving tech landscape. I thrive on challenges, love optimizing systems for speed and efficiency, and am always eager to learn and grow. Whether it’s scaling backend systems, solving algorithmic problems, or transitioning into new technologies, I’m excited about building impactful solutions. Let’s connect and create something amazing!

Two decades in the tech industry, I’ve been on a journey filled with hands-on innovation, leadership, and a commitment to making technology work for people. As the CTO of Loyal, I lead a global team focused on growing apps with subscriptions and our ad tech platform. At Loyal, I bring together 20 years of experience to drive success. My background in AdTech, honed at Veoh Networks and the Verve Group, alongside my skills in mobile and web development, allows me to lead our global team effectively.

I believe my experience in a multitude of Ruby on Rails roles has made me an extremely adaptable developer who can hit the ground running, pickup new codebases quickly, and reduce drag while onboarding. My experience in these roles have given me exposure to different areas of development, like writing unit tests, building RESTful APIs, WCAG accessibility compliance, and more.This experience will allow me to bring valuable skills and knowledge from the outside to help any new company build out solutions. Finally, I am extremely passionate about my career, my skills in development, and learning new technologies and methodologies that will help me learn more and become a more skilled and valuable developer as time goes on, and that motivation will help me succeed in any new role that I will occupy. Overall, I am a very self determined team player who is passionate about delivering high quality code, growing his skills, and delivering effective solutions for all types of problems.

Highlights: 10+ years of experience as freelancer in FinTech,Healtcare and HR applications Proficient in Ruby on Rails on the backend, and lots of other tech on the frontend. Specialized in optimizing, legacy code, database performance. Experience as DevOps well. Full background: As a nineties kid, I was already tinkering/dabbling around making games and invoicing software on our first pc at home. In university, while doing my engineering and mathematics degrees, I was scripting and using a lot of different technologies on complex physics problems. In 2012, I discovered Ruby/Ruby on Rails and a lot of things just clicked/felt right. I've specifically looked for RoR startups, joined an early stage FinTech startup that exploded and has had a successful exit. From then on, I turned it into my career and never looked back. I worked in FinTech, Healthcare, HR applications, picking up different domains and iterating upon complex calculations on the way. I've architected several green field/new applications from the ground up, all of them are still in use today. Amongst them are some high traffic enrollment systems in sports and leisure. I've worked with all Rails versions, even facilitating a migration from a huge (400 models plus) legacy rails 2 application to modern standards. Along the way, I've seen some very interesting PostgresQL optimization problems. You can't go so long and not pick up some DevOps as a side quest, so worked with terraform, chef, Ansible, Kubernetes and all kinds of provisioning/hosting/deployment tools and pipelines. I've used most modern frontend frameworks (React/Redux, Vue, Angular, Ember) on different projects but for smaller applications I tend to prefer to keep it simple using Hotwire. Always open for a chat to see what I can do for you!

Hi, I am a Software Engineer with 6+ years of experience in the tech industry. Highly skilled in Ruby on Rails, Node.js, JavaScript and React.

From the moment I wrote my first lines of code, I was drawn to the power of solving real-world problems through technology. Over the past 9+ years, I’ve honed my expertise in Ruby on Rails, Node.js, Python, Go, and React, building scalable, high-performance applications across FinTech, SaaS, and Healthcare industries. My passion lies in crafting robust backend systems, secure APIs, and seamless front-end experiences, all while optimizing for performance and maintainability. One of my proudest achievements was leading the migration of a monolithic Rails application to a microservices-based architecture using Go, Node.js, and GraphQL. By carefully refactoring services, implementing event-driven patterns with Kafka, and optimizing database queries, we cut response times by 60% and improved system reliability. This experience reinforced my belief that understanding the trade-offs of different technologies is key to building resilient applications. Beyond writing code, I thrive on mentoring engineers, leading technical discussions, and driving best practices in CI/CD, cloud-native development (AWS, Kubernetes, Terraform), and DevOps automation. I love tackling complex authentication challenges (OAuth, JWT, SAML) and designing secure, scalable APIs that empower businesses to move faster. At my core, I’m an engineer who bridges the gap between backend, frontend, and infrastructure—someone who doesn’t just build software but also optimizes it, secures it, and scales it. Whether it's refactoring legacy Rails applications, designing real-time systems with WebSockets, or deploying Go-based microservices, I bring a holistic, problem-solving mindset to every project.

Hi, I'm Mitch! I've been a Rails developer since 2012. Throughout my career, I've brought my unique perspective and skills to each project I've worked on. I love delving into legacy code, finding elusive bugs, upgrading systems, and documenting codebases. I take pride in my ability to leave a project better than I found it and in a place that can be easily picked up by another developer. I have been self-employed for 5 years and work well both independently and on a team. Being self employed has broadened my skillet more than I could have imagined, since I'm constantly being thrown into new and unfamiliar situations. Throw me into yours next!

My journey into software development started with a deep curiosity about how systems scale and handle complex workflows. Over the last 4 years, I’ve specialized in Ruby on Rails, PostgreSQL, and system optimization, working on high-impact financial platforms. At Vartana, I led the complete revamp of the servicing system, transitioning from invoices to account statements, improving financial tracking, and optimizing execution times by 67%. I also played a key role in migrating our entire system to Kubernetes, reducing deployment time by 83% while ensuring zero downtime. Beyond writing efficient and maintainable code, I excel at troubleshooting critical issues, optimizing SQL queries, and enhancing system performance. One of my proudest achievements was reducing page load times by 90% (20s → 2s), significantly improving the user experience. I’m passionate about scalability, DevOps, and financial systems—I love architecting solutions that not only work but scale seamlessly. Whether it's optimizing background jobs, improving API performance, or automating workflows, I thrive on making systems faster, more efficient, and easier to maintain. When others see a bottleneck, I see an opportunity to optimize. My unique skill set lies in blending backend development with DevOps, ensuring that applications run smoothly while remaining scalable and cost-effective. I’m always eager to collaborate with teams that value clean code, performance, and reliability. I’m open to remote opportunities where I can contribute my expertise in Rails, Postgres, and system architecture. Let’s build something great together!
