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 am an excellent Ruby on Rails developer with a full-stack proven history and a strong sense of generating business value. I can do everything from frontend to backend to hosting. I'm a good hire.

I am familiar with Ruby on Rails. I have developed web applications such as e-commerce, job boarding, payment gateway systems, project management systems, ai web applications etc., using Ruby on Rails, React, Angular, MySQL, PostgreSQL, SQL Server, HTML, CSS, SCSS, JavaScript, openai api etc. I have worked on both frontend and backend, implementing responsive pages using Active Admin, Foundation, Tailwind CSS, etc., as well as backend APIs and integrating third-party apis. Additionally, I have written test cases in RSpec, Capybara, Jasmine, etc and experience with agile development methodologies.

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.

A developer with a designer's attention to detail. Collaborating with design to create beautiful experiences. Building component and CSS libraries to facilitate modular development and application consistency.

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.

My values are collaboration, empathy, and work ethic. I've been working in Ruby on Rails for 10 years, and have seen a variety of different industries and different products. I focus on delivering quality products on-time and under budget. Reach out to discuss your needs!
