Hire mid-level Ruby on Rails developers in United States

Hi! I'm Liz 👋🏼 I'm about as full-stack 🥞 as they come. I started as a QA and automation engineer and now I'm a senior full-stack engineer focusing on Rails and React. Early on as a QA I worked on projects from writing SQL scripts to check data, to automation engineering, to React Native applications, and even helping implement Kafka instances and a team transition to Kubernetes. Then I moved on to development, mostly focusing on Rails / React stacks. I also am very comfortable working in Python. Now I've been a full stack developer for a few years, always carrying my QA mindset with me. I love exploring the ins and outs of a problem, and figuring out where I can pick it apart and expose weaknesses. I'm really great at building relationships with stakeholders, establishing trust and cooperation so that we can all move forward with a project in a very pragmatic way. Pairing with coworkers is always very enjoyable for me. I like the collaboration, but I really value the mentorship the most. Teaching juniors git has become a mainstay for me, as well as coaching them to maintain a calm mindset while debugging, encouraging them to move through issues in a systematic way. And of course I always fit in robust testing, showing folks how to create test suites and pipeline automation that will improve their workflow. Let's talk about how I can contribute to your team and stack 🙌🏻

I initially went to school for linguistics—studying a variety of different languages, before learning that it is difficult to make a living as a linguist. So reluctantly, I became a developer. Then I discovered something that surprised me—I enjoyed it. What's more, I discovered that my linguistics background gave me a huge leg up and programing was easy to learn. I worked in React and JS for a bit, before switching to Rails and doing that full time. Since starting, I have built and maintained a Rails application from scratch. And I have become a member of the community surrounding Bullet Train. That work has given me a deep understanding of MVC, RESTful architecture, and the Rails Way. I love working in Rails and I also am very comfortable in Bullet Train.
