Hire medio freelance Ruby on Rails developers in United States

I didn’t start out planning to be a developer—but solving problems though applied technology pulled me in. What began with scripting solutions for tedious workflows turned into building full-scale platforms used by thousands. Today, I’m a full-stack developer and technical founder with a deep understanding of both code and the business logic behind it. I have worked across both public and private sectors, and in industries ranging from Logistics and Aviation, to Retail and Education. My early career experience as a solutions architect reinforced my customer and user concentric approach. What sets me apart isn’t just the code I write—it's my ability to understand what users actually need and deliver scalable, elegant solutions that exceed expectations.

With 5+ years of Rails experience, I come with a wide range of experiences and love to delve into new projects. I am working on a variety of pure Rails apps, leveraging the power of Hotwire and TailwindCSS on the front end. My personal project is https://anecdot.co, a platform for recording, preserving, and sharing life stories.

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.

I’m Alex Smith — a senior full-stack software engineer with over 9 years of experience building fast, elegant, and resilient systems. I began my career on Wall Street, where I developed a deep understanding of performance, precision, and high-stakes infrastructure. Since then, I’ve brought that same rigor to startups and fintech companies, designing scalable backend architectures, crafting intuitive user interfaces, and leading cross-functional teams through complex technical challenges. Whether it’s shipping high-impact features, optimizing performance, or diving deep into system observability, I bring a pragmatic, detail-oriented approach to everything I build. Beyond code, I’m a hands-on problem solver who enjoys tackling real-world challenges — from modifying cars in my garage to chasing par on the greens. I’m always exploring new tools and technologies, and I thrive in environments where curiosity meets execution.
