Hi, with 7+ years of experience as a Ruby on Rails and full stack developer, I excel in building dynamic and scalable web applications. My expertise spans across a range of JavaScript frameworks, including ReactJS, NextJS, NodeJS, NuxtJS, and VueJS. I combine my strong backend skills with modern frontend technologies to deliver seamless, high-performance solutions My journey started with a keen interest in technology and quickly evolved into working on complex projects. Recently, I led a team to build a scalable microservices-based application, which enhanced both user experience and performance. I’m also exploring serverless technologies, like AWS Lambda, to improve application efficiency. What makes me stand out is my ability to handle both frontend and backend development, solve tough problems, and create user-friendly solutions. My diverse skills and hands-on experience make me a strong addition to any development team. Let’s build something great together!

I wish I would have been exposed to programming much earlier in life. The first programming book I read was "Learn Ruby the Hard Way" by Zed Shaw. That, coupled with an interest in graphic design seemed like a gateway into a very enjoyable career where I could be logical and creative! Shortly after, I joined a bootcamp in 2016. I've worked with quite a few frameworks and libraries since 2016. Here's what I've learned: - Ruby is super fun, Rails is not dead, convention-over-configuration is my preference whenever possible. - JavaScript is cool but the front-end world can be exhausting; too much reinventing the wheel and forgetting about web fundamentals. - I enjoy CSS a lot. - Hotwire and Stimulus are a very cool approach to efficiently providing a user with a SPA-like experience - I'm proficient in React but like to keep it simple, sustainable, composable. I strive to find the appropriate balance of simplicity and complexity in order to: - meet the project needs - be considerate of fellow developers who will need to read, understand, work with the code I write - enable Junior devs to step into the codebase and understand/mimic/extend the codebase. Unique Traits: - Trilingual (English, Spanish, French) - Education background (I can mentor Junior devs) Positive Traits: - Passionate about good quality - Tenacious Personal focus: - I've been focused on diving deeper into the Rails ecosystem and my aim is to find a role with a company using Rails + Hotwire, or Rails + React. NOTE: The link "Website" link in my bio is Github. I'm currently redoing some portfolio projects.

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, Minitest, Capybara, Postgres, Tailwind, and jQuery. 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

TLDR- I know Rails, let’s build together. I understand that the most important part of any project is getting it in front of users. I am the ultimate buy one get one free; a true full stack developer with years of experience working with Rails and React. Let’s leverage my skill set to get your idea from in your head to on the web. Skills Great knowledge of Ruby. Experienced Next/React user. Sidekiq expert. Domain Modeling. CSS (SCSS, StyleComponents, Tailwind, Bootstrap, Whatever is clever). API’s and Integrations are my jam. I am very familiar with the JavaScript ecosystem including modern React and the current rise of hypermedia on, over, or around the wire. From LiveView in Phoenix, to Hotwire and HTMX, I’ve hosted projects in each. Legacy Code I have experience working with large media organizations that managed many forms of media from digital to printed magazine. Magazine systems are archaic, and very brittle. I refactored America’s Test Kitchen’s subscription service, allowing for greater resilience and capture. I am currently working for an enterprise grade e-commerce platform. We leverage Rails (Sidekiq) and process ~billion jobs a day.
