Rails + Hotwire 🏗️

Recently updated

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 I developed cross-platform applications using Turbo Native. I optimized high-traffic pages, reducing load times by an impressive 80%. Additionally, I improved database performance through query optimization, task offloading, caching, and refactoring model associations. 📈 I also collaborated with digitalwildcatters.com on a contract basis, where we developed a cross-platform application using Ruby on Rails and Turbo Native (Jumpstart Pro). I 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 I contributed to remarkable projects like plt4m.com. I solved user stories by creating models, writing ORM queries (Sequel), conducting testing (Mini & Capy), and implementing responsive CSS. Another notable project was haymakersforhope.org, where I integrated a Strapi API for a headless CMS and designed a responsive interface using Tailwind. 🏆 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
