Hire Ruby on Rails developers

Hi, I'm Mike. Over my career, I've worked at a variety of companies of different sizes and problem domains. I've seen a lot of what works and what doesn't, so I think I can provide insight on processes and approaches to common problems teams run into. I do my best work when given a goal. I like to focus on the product first and the rest can always be improved upon later. I'm big on testing and I use TDD often. TDD helps me move quickly. As the first hire at a fintech startup: * Built and launched the initial version of the product. * Interviewed candidates for both technical and behavioral assessments. * Recognized as employee of the month in Feb '23 for embracing ownership. I came up with a way to reduce the company's risk. * Recognized as employee of the month in Jun '23 for embracing simplicity. I helped launch a large feature in a short amount by working closely with product to reduce the scope. * Built, maintained, and improved the core product that has led to a Series A.

Young Greek based in Brussels, open to relocation for the right opportunity. With a background in Electrical and Computer Engineering, I further honed my skills by completing an intensive six-month coding boot camp, focusing on full-stack web development. These days, I stay committed to learning by taking online courses, exploring technical materials, and occasionally working on freelance projects. Additionally, I actively work on enhancing my boot-camp's final project, refining its features, optimizing its performance, and deepening my understanding of AI integrations and web development best practices. During this project, I developed an AI-assisted board game companion in the form of a web app and our team’s project proudly earned 2nd place in our cohort. Some key features of this project were: ChatGPT API Integration – for dynamic content creation Stable Diffusion (Self-Hosted) – quick and responsive AI art generation on demand ActionCable & Sidekiq – for real-time data exchange and background job processing 🚀 I'm looking for a Junior Developer role where I can contribute, learn, and grow—let's connect! Tech Stack & Expertise ✅ Ruby on Rails ✅ HTML, CSS, Bootstrap ✅ JavaScript (AJAX, Stimulus) ✅ WebSockets ✅ Sidekiq ✅ SQL & PostgreSQL

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.

Hey there! I'm an experienced software developer with a strong background in Ruby on Rails, Hotwire (including Turbo, Stimulus, and Turbo Native), Jumpstart Pro, APIs, Postgres, Tailwind. I'm really passionate about crafting high-quality, efficient, and user-friendly applications. Recently, I completed a contract with inkwire.co, where we developed cross-platform applications using Turbo Native. We optimized high-traffic pages, reducing load times by ~80%, we improved database performance through query optimization, task offloading, caching, and refactoring model associations. I also collaborated with collide.app on a contract basis, where we developed a cross-platform application using Ruby on Rails and Turbo Native (Jumpstart Pro). We implemented intuitive UI/UX designs using Tailwind CSS, ensuring a seamless and visually appealing user experience. Prior to these contract roles, I worked with oblsk.com, where we contributed to remarkable projects like plt4m.com. We solved user stories end to end, conducting testing (Mini & Capy), and implementing responsive CSS (Tailwind). Another notable project was haymakersforhope.org, where we integrated a Strapi API for a headless CMS and designed a responsive interface using Tailwind too. In my spare time, I'm dedicated to giving back to the community through organizations like Ruby for Good. I've actively participated in their CASA project, assisting with both small and large issue resolution. Collaborating with like-minded individuals to make a positive impact is truly fulfilling. I consider myself on being resilient, resourceful, and emotionally intelligent. I possess strong communication skills and always strive to deliver on time. 🇺🇸 English - Professional 🇲🇽 Spanish - Native CASA project: https://github.com/rubyforgood/casa/commits/main/?author=dominiclizarraga Personal blog: https://github.com/dominiclizarraga Resume: https://standardresume.co/r/YcQ-LtWoMGJlQFJz4IvH5

What makes me unique as a developer is the blend of purpose, adaptability, and real-world impact that drives my work. I didn’t get into software development simply to build cool apps — I started coding to solve problems that matter to people. From streamlining administrative systems for local government in Zimbabwe to creating an online marketplace that helps small businesses sell car parts more effectively, my projects are always rooted in tangible value and usability. One of my recent accomplishments is developing a digital change-of-use permit system for Harare City Council using Ruby on Rails. What makes this special isn’t just the tech stack — it’s the fact that I took a bureaucratic, paper-heavy process and transformed it into something efficient, trackable, and accessible. It’s a small but meaningful contribution toward digital transformation in a context where it's needed most. I’m passionate about building platforms that empower communities, particularly in underserved markets. Whether it’s launching PartsToGo, a growing car parts marketplace in Zimbabwe, or conceptualizing platforms like TendersZimbabwe, I love taking on the kind of challenges where impact matters more than hype. I bring not only the technical skills — full-stack development, systems thinking, clean and maintainable code — but also a strong sense of empathy and purpose to every line I write. I thrive where others may hesitate: limited resources, unclear paths, and bold ideas. My strength lies in turning vision into product, especially when the goal is to make life easier, more efficient, and more just for real people.

I am a seasoned Ruby on Rails Engineer who has been using Ruby 2.2.10 and Rails since 5.0.1. I have a proven track record of building and launching successful products including 2 public Shopify Apps. I am always aware of the performance of the applications and how I can improve them. I am highly motivated to contribute, learn, and grow within the industry. My passion for new products and technologies drives me to collaborate effectively with diverse teams and deliver exceptional results.

After bootstrapping and exiting a successful Rails SaaS as both principal engineer and CTO, I decided to focus back on my passion for engineering and architecture. I joined a remote-only startup building a new product with the goal of using the traditional Rails paradigms along with tried and tested technology to quickly get a comprehensive product to market. That "keep it simple" approach got the product into the hands of some of the most recognizable brands in the world. Feature development turned into performance and growth engineering, again, using the same mentality of finding the simplest most effective approach. I am an excellent generalist with experience in most traditional Rails stacks from backend to frontend and able to easily adapt to new technologies (but only where warranted!) I enjoy the challenge of a fast paced startup world of executing on ideas and providing solutions for customers problems with quick deployment and iterative improvements.
