Hire junior freelance Ruby on Rails developers

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 had the pleasure of working 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

Hi, I'm Mwala and I love building for the web. I have been writing rails programs since 2022 and I have been hooked to this framework ever since. Rails really brings out the creative in me what people online call the developer brain. The framework's full-stack experience is one I have really enjoyed especially when you integrate Hotwire 🔥. I used django before and had a good experience with it won't lie. I have also done so work with Gin with go-lang and React just for the frontend(that what it should be used for). I have done some game development in the past and computer vision work, it was an exciting time. Game dev is something I might go back. Okay, I don't spend all my time on development, I try my best to stay in shape, football (soccer) being my go to sport. I really like watching and playing the sport. I think If I wasn't a developer I would have been playing football professional 😎. I have gotten into the habit of watching the UFC and motorsports, F1 to be specific and tennis, man I wish I knew how good this game was.

Hi there! I am an experienced Ruby on Rails developer. I am an immediate joiner. I love new challenges and meeting new people. I am comfortable with both remote and onsite with relocation assistance.

I'm a self-taught Rails developer and creator of Membership System Pro, a Ruby on Rails gym management software, designed for nimble businesses. I initially built it as a labour of love for my partner’s fitness business. A Pilates studio owner had a positive experience with the software as a visitor to my partner’s studio. She reached out to me to implement it for her own business and soon became my second (and first paying!) client. Selling services to a second client required me to draw on my broader business experience from my first career as a consultant. I communicated openly with the client to assess requirements and provided a formal contract to document specification, charges and delivery. On the technical side, I particularly enjoyed implementing a bespoke solution for a tricky membership policy the client had, where certain members had priority booking rights over certain classes. Membership System Pro will remain a side project that I am keen to improve and expand use of, however, now, I'm eager to join a small, passionate team working on something interesting—where I can contribute, learn, and grow alongside other developers.
