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, As a ruby on rails developer I know what it takes to build a webapp from the ground up. To verify my experience, please check my github azeemh, and sign up for my free platform, Zedtopia. By seeing my open source code and reference projects you can see how I code in simple contexts. Going to see my work live on the web will better show you what I have built and what I am capable of coding in more complex and fully featured applications. Should we interview and agree to mutual NDA, I can also explain to you how I coded any features of interest and screen share as I walk you thru the source code, line by line. I have 2 apps live in production. Zedtopia is a socioeconomic network with democratic voting and social commerce. At this point, it's a full fledged product beyond mvp, migrated from ruby 2.7.6 & rails 5, to ruby 3.2 and rails 7, with a postgresql db. See https://www.zedtopia.com. Unlimit3d is an MVP 3d printing blockchain app, currently adding printing verification and purchase, with API partners, however users can currently sign up, upload, and share their files. Unlimit3d uses rails 7, ruby 3.2 and postgresql. See https://www.unlimit3d.com. I also helped to code connect.berniesanders.com for the 2015-2016 election cycle, which served over 200k simultaneous logged in users at any given time. Finally my personal website is found at http://www.azeemhussein.com, with my resume available at www.azeemhussein.com/resume. There you can see my designs, some cool interactive software exhibits, whitepapers, and more...
