Hi, I'm Mwala and I love building for the web. I have been writing rails programs since 2022 and I have been hooked to this framework ever since. Rails really brings out the creative in me what people online call the developer brain. The framework's full-stack experience is one I have really enjoyed especially when you integrate Hotwire 🔥. I used django before and had a good experience with it won't lie. I have also done so work with Gin with go-lang and React just for the frontend(that what it should be used for). I have done some game development in the past and computer vision work, it was an exciting time. Game dev is something I might go back. Okay, I don't spend all my time on development, I try my best to stay in shape, football (soccer) being my go to sport. I really like watch and playing the sport. I think If I wasn't a developer I would have been playing football professional. I have gotten into the habit of watching the UFC and motorsports, F1 to be specific.

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 really passionate about crafting high-quality, efficient, and user-friendly applications. 💻 Recently, I had the pleasure of working with inkwire.co, where I developed cross-platform applications using Turbo Native. I optimized high-traffic pages, reducing load times by an impressive ~80%. Additionally, I improved database performance through query optimization, task offloading, caching, and refactoring model associations. 📈 I also collaborated with digitalwildcatters.com on a contract basis, where we developed a cross-platform application using Ruby on Rails and Turbo Native (Jumpstart Pro). I implemented intuitive UI/UX designs using Tailwind CSS, ensuring a seamless and visually appealing user experience. 🌈 Prior to these contract roles, I worked with oblsk.com, where I contributed to remarkable projects like plt4m.com. I solved user stories by creating models, writing ORM queries (Sequel), conducting testing (Mini & Capy), and implementing responsive CSS. Another notable project was haymakersforhope.org, where I integrated a Strapi API for a headless CMS and designed a responsive interface using Tailwind. 🏆 In my spare time, I'm dedicated to giving back to the community through organizations like Ruby for Good. I've actively participated in their CASA project, assisting with both small and large issue resolution. Collaborating with like-minded individuals to make a positive impact is truly fulfilling. 🌿 I consider myself on being resilient, resourceful, and emotionally intelligent.
