Hire senior freelance Ruby on Rails developers

I like to design & build web products for clients. I also like to drink coffee, admire architecture, and look for practical & affordable ways to make things. I'm always looking to collaborate with good people who also want to build nice things.

As an accomplished senior Full Stack developer with 9 years of mastery in Ruby on Rails and Single Page Application (SPA) development using React, Vue.

Hi, I'm Wolfgang, senior software engineer and software architect. Everything's too complicated and you feel like nobody understands what's going on in your systems anymore? New features take long to implement and always introduce unforeseen new issues? With an exceptional ability to visualize and understand the interactions within large systems, I'm skilled in fixing and improving existing systems as well as designing scalable and maintainable new software architectures. I specialize in backend and full-stack development and have over 20 years of experience utilizing a broad range of technologies. I work with businesses of all sizes, from small startups to large enterprises and help them build and maintain robust, scalable solutions. 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.

My strength is working with the non-technical. If you're here, you probably know what you want or need, but maybe you don't know how to best accomplish it. I can help with that. Do you need someone who understands projects might have many stakeholders and need to be ready to pass along or pick up and pivot? I'm here for that. I'm currently open for project-based work. If you need something done, and need someone who can do it with as much or as little help as possible, let's talk. My stats: I'm a senior dev (10 years in Rails, 20 in web dev) who's been through dialup (14,400 even), Flash and ColdFusion, DHTML, I remember when JavaScript was invented, and I provision servers for fun. I'm a Rails dev who aligns closely with the Rails ethos on most things. Importmaps and Hotwire and Turbo and Stimulus are great fun. Familiar with teamwork (read: merge conflicts) and maintaining healthy relationships (read: no ego, just aiming for the best code). If none of that means anything to you, then all I'm bragging about is that I know how to start from nothing and build an entire infrastructure. I can work with a team or by myself equally well. If you know exactly what you want: shoot me a list. If you're a bit lost: let me help. If nothing else, I'm thrilled that I might get to talk shop with new people. Tell me about your project!

I became a full-time developer 20+ ago and have worked with a wide variety of languages and frameworks and held many roles. I started using Ruby and Rails in 2005 and it's by far my preferred toolkit. I enjoy working with legacy code bases and upgrading and improving them. I've spent a great deal of time on such tasks. My first project was a publishing solution for a major US shipping magazine called Pacific Shipper using AppleScript as the glue. It had everything: a GUI, import and export modules, networking, database interaction and Web publishing via ColdFusion. It was a wizard-driven conversion tool for porting a digital print file to a Web site. Along the way I got to experience most challenges facing a young and inexperienced developer, including how to interact with end users and product owners, bug fixes, deployment and versioning and more. The classic learn-as-you-go scenario. Since then, I went into ASP, Java (J2EE, JSP), build and deploy tooling, Struts and finally landing on Ruby and Rails in 2006. This has been by far my preferred toolkit since then. I have a passing acquaintance with iOS and Android development as well though would need a refresher. Having worked almost exclusively on the backend of things, with the arrival of Rails 8 I have happily re-entered the frontend domain and find it very rewarding. I consider myself a life-long learner and have over the years picked up useful soft skills, having worked in many diverse situations. I've lived and worked in many geographic location as well and am native in English, Swedish and German, fluent in French. In the past I have contributed to most phases of product development, from concept and wire framing to server setup. I've spent a significant amount of time in e-commerce and content management systems. I enjoy seeing a project from a high level perspective, rather than starting at a database schema level: outside in rather than inside out. I consider myself a pragmatist and will not by default try to build everything myself if a reasonable alternative exists. By the same token, I'm in favour of carefully curating and vetting libraries to include in a project. I prefer to move with a purpose and shipping often rather than sitting on a feature until it's "perfect". I have no bias against working with legacy code, in fact I enjoy it! Spelunking is a a great way to learn and understand.

With over 15 years in software engineering, my primary expertise lies in Ruby on Rails, a framework that has been my trusted companion for over a decade. I also possess strong skills in various other programming languages, including Python, Node.js, JavaScript, and Java. My passion for technology goes beyond conventional web development. I'm well-versed in mobile app development, having worked with Android, Flutter, and even creating interactive HTML5 games with Phaser. My diverse skill set allows me to tackle a wide range of software projects. What sets me apart is my commitment to clean, maintainable, and highly readable code. Ruby on Rails, in particular, has been my tool of choice, as it not only enhances my productivity but also ensures codebase elegance. In the ever-evolving world of web development, staying agile and adaptable is essential. As a Full Stack Engineer, I thrive in both front-end and back-end domains. My experience extends to crafting responsive web designs, using tools like Bootstrap, HTML5, and CSS3. I am proficient in popular front-end frameworks, such as React, Vue, Ember.js, and Lightning. My hands-on experience in deploying applications to production environments is extensive, with expertise in platforms like Amazon AWS and Heroku. I have a proven track record of delivering robust, scalable, and secure solutions that meet the needs of modern businesses. If you're looking for a seasoned Full Stack Engineer with a deep understanding of Ruby on Rails and a versatile skill set in web and mobile development, I'd love to connect and explore how we can collaborate on your next project or venture.

I am a software engineer, programming mentor, and tech intrapreneur. I specialize in building elegant and functional web solutions, primarily using Ruby on Rails. With over ten years of experience, I've developed a diverse portfolio of web applications and services using Ruby, JavaScript, Node.js, and more. My expertise extends to integrating web services, scaling applications, and managing infrastructure and security across numerous projects. Beyond my professional work, I mentor students and professionals looking to develop their Ruby and JavaScript skills. Sharing knowledge and helping others achieve their goals has become a rewarding extension of my career. I approach technology not as an end goal but as a means to solve meaningful problems. This perspective is reinforced by my practice of Parkour, whose philosophy of overcoming obstacles and adapting to challenges influences how I approach both programming and life.

I'm a full stack (plus devops, plus data eng) developer with a penchant for human interaction. In the past, I've thrived in "solutions" roles, I've gotten a solid start on management skills, and I've helped launch many a startup. I love mentoring junior devs and helping a company have an excellent technical and social culture.
