Hire senior Ruby on Rails developers

Hi! I'm a passionate Rails dev with over 7 years of experience in delivering web and mobile applications. My approach is product-oriented — I focus on getting features out quickly and efficiently, prioritizing delivering real value over obsessing about code perfection. I understand how to align technical solutions with business goals. I’m skilled in both backend and frontend development, allowing me to tackle any challenge that comes my way. Over the past two years, I have primarily focused on Shopify apps. I built two new apps and provided support for two existing ones. I’ve also served as a team lead and was a Ruby mentor on the Hexlet platform, where I taught students Rails

Software engineer & DevOps with 15+ years of experience in applications development and infrastructures management. I offer a wide range of services from Ruby on Rails projects consulting and development to the deployment of cloud infrastructure on Amazon Web Services.

Hi, I'm Wolfgang, senior software engineer and software architect. I specialize in backend and full-stack development. With over 20 years of experience utilizing a broad range of technologies, I have a proven track record of building and designing robust, scalable solutions for businesses of all sizes, from small startups to large enterprises. With an exceptional ability to visualize and understand the interactions within large systems, I'm skilled in designing scalable and maintainable software architectures. For more details please see my website and feel free to contact me if you have any questions or just want to get in touch.

I’ve always been fascinated by the intersection of creativity and technology. My coding journey began when I discovered how a few lines of code could transform an idea into a fully functioning application. From that point on, I was hooked: I poured countless hours into experimenting with everything from Ruby on Rails to more modern JavaScript frameworks. Over the years, I’ve refined my skills and found my passion in building clean, maintainable systems that put user experience first. One of my proudest earliest accomplishments involved leading a small team to develop a custom internal tool that automated a tedious data-entry process. Seeing the hours of manual work drop to just a few minutes was incredibly rewarding—it reminded me why I love being a developer in the first place. I’m constantly seeking new ways to grow: whether that’s diving into emerging technologies, improving my testing strategies, or exploring new coding paradigms, I believe there’s always more to learn. Above all, I thrive on solving tricky problems in ways that others might not have considered. I love collaborating with designers, project managers, and fellow developers to turn concepts into polished products. I bring a unique blend of empathy, curiosity, leadership and technical expertise that helps me bridge communication gaps and ensure every project is set up for success. Helping teams build something truly meaningful is what drives me—and I’m excited for what comes next.

Software Engineer with 10 years of experience in developing & managing web applications, web scripting, database designing. Seeking a position where I would be able to use the knowledge gained in the software development cycle and technical aptitude.

I have almost a decade of experience in web development and possess advanced software engineering skills. I’ve built and maintained apps about education, mental wellness, legal assistance, video streaming, and payment processes. I had many roles, including a Tech lead, teacher, mentor, speaker, Full Stack, and Backend engineer. Furthermore, I am an active member of the tech community. I organize events at Ruby Peru, speak at various local and international events, and serve as a Women TechMakers ambassador and #IAmRemarkable facilitator to encourage women's participation in technology. My previous employees were Shopify, CloudForecast, Able, Platzi, and devAcademy. I am also a strong collaborator and team player, and I enjoy working with others to solve complex problems. I am comfortable working in an Agile development environment and have experience in both front-end and back-end development. In addition to my technical skills, I am a quick learner and am always eager to expand my knowledge and skill set. That helps me to switch technology easily. I've worked with Ruby on Rails (Ruby), Django (Python), React & React Native (JavaScript and TypeScript), Electron, and Vue. However, my top priority is being a parent. I enjoy spending time with my child and being there for their growth and development.

A little about myself: I've been working commercially in software for just shy of two decades. The majority of that time I've been working as a full-stack Ruby/Rails Product Engineer, and involved in local community projects like RailsGirls and even organising a couple of Australian RubyConfs of my own. More recently I've found a passion for leading technology teams both at very large scales (at places like Qantas), and much smaller scales in my current role as Head of Engineering at an Australian RegTech startup - and everything in between. I'm a great solo operator, but love working in pairs, teams, or leading larger groups. I would consider myself a 'true' full-stack engineer: I love every part of the stack from CSS through to infrastructure, and have a passion for good visual design and building great user experiences What I'm looking for right now the is opportunity to have a lot of operational and tactical delivery impact. I would consider leadership roles for the right organisation, but would probably be better suited to a short term contract with a focus on output. What I'm looking for long term is a supportive, ambitious (but with realistic goals) company, full of great people trying to build something cool. I'd love the opportunity to have influence at a more strategic level within an organisation, alongside a supportive team. And if I'm being transparent I've struggled thus far to find the right 'fit' in this regard: either too little influence; or too much scope (and not enough support) in the role.

Ruby Developer

I’m a Rails developer with over 12 years of experience in software development, including 10+ years working hands-on with Ruby on Rails. Along the way, I’ve built all kinds of applications—automation tools, ERPs, inventory management systems, insurtech platforms, social media apps, and even AI-integrated solutions. I’ve always focused on creating large-scale, high-performance apps that can handle thousands of concurrent records without breaking a sweat. I’ve worked with both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases, making sure they’re set up for speed and scalability. On the backend, I’m well-versed in Sidekiq and RabbitMQ for background processing, and on the frontend, I use tools like Hotwire, Turbo, and Stimulus to make apps fast and interactive. When it comes to deployment, I’ve got plenty of experience with Google Cloud, AWS, and Fly.io, which lets me build infrastructure that’s as reliable as it is scalable. What makes me stand out? I code fast. Really fast. I’m great at taking an idea from zero to a fully functioning app in just days, without cutting corners on quality. Having worked in Asia and Europe, I’ve learned how to adapt to different clients and challenges, which helps me deliver exactly what’s needed, every time. Recently, I co-founded my own software consulting firm, where I get to use my skills and experience to help businesses grow and succeed. Outside of coding, I’m passionate about dogs, I love solving crosswords, and I’m a bit of a political nerd. These hobbies keep my mind sharp and my creativity flowing, which is probably why I enjoy tackling complex coding challenges. I know Ruby and Rails inside out, and I thrive on turning big ideas into reality—quickly and efficiently. If you need someone who can hit the ground running and deliver results, I’m your developer.
