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 ~100M jobs a day.

My professional career began in 2019 as a Ruby on Rails developer. Since then, I've honed my skills in Ruby on Rails, API integrations, and full-stack development, primarily building e-commerce platforms. The business challenges I encountered in client meetings always pushed me to provide scalable and efficient solutions. One of my proudest accomplishments was working on a large-scale project with 200+ e-commerce clients. My contributions were recognized, and I was promoted to Software Engineer, where I also mentored new team members on the project and Ruby on Rails. I'm passionate about delivering clean, optimized code and always eager to learn new technologies. Recently, I've been diving into API design patterns and exploring AWS services to improve application scalability. My ability to collaborate across teams, adapt to new tools, and consistently deliver high-quality solutions makes me not just a developer, but a problem solver who thrives in fast-paced environments. Apart from coding, I'm also an artist who loves to paint with different mediums. I believe that my artistic skills help enhance my imagination power, creativity, and concentration, which directly contribute to my problem-solving approach in development. I'm excited to bring my technical skills, attention to detail, and passion for building impactful applications to a team that values innovation and customer success.

From the moment I wrote my first lines of code, I was drawn to the power of solving real-world problems through technology. Over the past 9+ years, I’ve honed my expertise in Ruby on Rails, Node.js, Python, Go, and React, building scalable, high-performance applications across FinTech, SaaS, and Healthcare industries. My passion lies in crafting robust backend systems, secure APIs, and seamless front-end experiences, all while optimizing for performance and maintainability. One of my proudest achievements was leading the migration of a monolithic Rails application to a microservices-based architecture using Go, Node.js, and GraphQL. By carefully refactoring services, implementing event-driven patterns with Kafka, and optimizing database queries, we cut response times by 60% and improved system reliability. This experience reinforced my belief that understanding the trade-offs of different technologies is key to building resilient applications. Beyond writing code, I thrive on mentoring engineers, leading technical discussions, and driving best practices in CI/CD, cloud-native development (AWS, Kubernetes, Terraform), and DevOps automation. I love tackling complex authentication challenges (OAuth, JWT, SAML) and designing secure, scalable APIs that empower businesses to move faster. At my core, I’m an engineer who bridges the gap between backend, frontend, and infrastructure—someone who doesn’t just build software but also optimizes it, secures it, and scales it. Whether it's refactoring legacy Rails applications, designing real-time systems with WebSockets, or deploying Go-based microservices, I bring a holistic, problem-solving mindset to every project.

Hello! I am a Rails and frontend developer who has worked at a variety of small companies and startups in various industries. This means I am a versatile problem solver who focuses on getting to the core of business problems before implementing solutions. In addition, I love working with people and am an engaged and helpful teammate. Recently, I have been working for a client on upgrading older Rails versions, implementing enhanced security mechanisms using devise and MFA, and of course building out features (e.g. billing). I have some strong AWS knowledge as well. I look forward to working with you!

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 🙌🏻

Hi, I'm Mitch! I've been a Rails developer since 2012. Throughout my career, I've brought my unique perspective and skills to each project I've worked on. I love delving into legacy code, finding elusive bugs, upgrading systems, and documenting codebases. I take pride in my ability to leave a project better than I found it and in a place that can be easily picked up by another developer. I have been self-employed for 5 years and work well both independently and on a team. Being self employed has broadened my skillet more than I could have imagined, since I'm constantly being thrown into new and unfamiliar situations. Throw me into yours next!
