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 🙌🏻

Building software for over a decade. Mostly with Rails, sometimes without. Interested in working with early stage startups or small tech-enabled businesses.

Software developer with over 4 years professional experience as a Ruby on Rails developer. I have worked with teams in various sectors including healthcare, human resources, co-working space, fintech, and Edtech. I also write technical articles based on Ruby on Rails. My experience working remotely for many years provides me with the requisite skill set to excel in a similar role. I enjoy watching/playing football, hanging out with family and friends.

I am a software engineer, programming mentor, and tech intrapreneur. I specialize in building elegant and functional web solutions, primarily using Ruby on Rails. I've spent the last 10 years helping tech companies make the world a better place. In addition to lead entire projects from conception to shipping, I've demonstrated excellent communication skills. Through years of experience, I've engaged in articulate discussions, both written and verbal, with fellow developers, project collaborators, and stakeholders. My track record includes skillfully presenting complex technical concepts, contributing to detailed technical documentation, and fostering clear communication channels crucial for streamlined collaboration in software development projects. I have also showcased robust leadership skills by overseeing and managing a team of fellow software developers, steering daily operations within the technical domain. My experience extends to offering guidance and support to team members, establishing performance standards, delivering constructive feedback, and adeptly addressing challenges as they emerge. Additionally, I have taken an active role in mentoring junior developers and nurturing aspiring talents within the software development field. Looking forward to hearing from you!

Started off back in 2012 as a junior VOIP admin in a small startup. When I saw the guys coding around decided to give it a shot with Rails for Zombies and boom, instead of doing admin stuff I was coding. I've been doing billing for the past 9 years so eventually became the engineering manager billing.

With more than 10 years of experience in Ruby and Ruby on Rails, I have a track record of delivering high-quality solutions that meet both functional and design requirements. Throughout my career, I have collaborated closely with product managers and UI/UX designers to scope, design, and implement complex projects. I have also worked with both back end and front end technologies, including React with TypeScript. In addition, I have some experience with a variety of other programming languages, including Go, Elixir, C++, Haskell, Python, and Java, as well as developing my own toy programming languages and DSLs. As a passionate learner, I am always looking for opportunities to work with like-minded people and build the best software possible. During my PhD, I worked on the open-source project Bohrium, which allows for automatic parallelization of NumPy and Ruby code written in C++. Additionally, my implementation of a CSP framework for Ruby benchmarked better than the Python implementation at the time. I am comfortable working remotely and believe that effective communication is key to successful collaboration. When I am not at my computer, I enjoy geocaching, playing board games, and cooking. Jokingly, I have made stickers for my own jam brand. I am committed to becoming the best version of myself and would welcome the opportunity to bring my skills and enthusiasm to your team.
