Hire mid-level freelance Ruby on Rails developers

I’m a backend-focused developer with 2 years of hands-on experience building with Ruby on Rails. My background includes a Master’s degree in Computer Science, and I bring solid fundamentals to the table—data structures, algorithms, and system design. Recently, I’ve been diving deep into Elixir and Phoenix, and I’m excited about the power and concurrency they offer. I enjoy learning how things work under the hood and don’t shy away from low-level details or unfamiliar tech. I’m the kind of developer who reads the docs, checks the source code, and asks why, not just how. While I’m not a frontend or design expert, I can build full-stack features end to end when needed. I’m highly adaptable, pick up new concepts fast, and care about writing clean, maintainable code. I thrive in backend-heavy environments where architecture, performance, and reliability matter.

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’m a senior developer and product strategist with 10+ years building custom software, mostly with Ruby on Rails. I turn complex problems into fast, scalable solutions—and I always build with the end user (and the business) in mind. I got into dev through entrepreneurship—building tools to run my own businesses. That mindset never left. I think like a founder, move fast, and care deeply about results. Lately, I’ve been focused on integrating AI into products: • Automating workflows with tools like OpenAI, Make.com, and LangChain • Building AI-powered features that enhance user experience and drive growth • Helping SaaS teams use AI to scale smarter without adding headcount I’ve led everything from zero-to-one builds to product turnarounds, working closely with founders and small teams. I thrive in fast-moving environments where priorities shift and speed matters. When I’m not building software, I’m in the mountains snowboarding, hiking, or chasing the next great view. Let’s connect if you need someone who can think strategically, code fast, and actually ship.
