Lead dev specialising in clean, maintainable code and keeping tech debt low

I'm a full-stack Rails developer with experience building robust, scalable products, whether as a Ruby monolith or with TypeScript/ReactJS frontends. I've been working with Rails for over 10 years (since version 3.x) and have specialised in creating and maintaining codebases that are easy for teams to read, understand, and maintain. Key to those goals are: using standardised code styles (ensuring RuboCop and the team's practices are perfectly aligned) writing well-structured, easy-to-understand and fast tests constructive and collaborative code reviews ensuring documentation, from git histories to READMEs and other materials (online and offline) records useful, meaningful information that can be easily kept up to date and in sync with any code changes I've recently been adding GraphQL to my skill set, which also includes PostgreSQL, ElasticSearch, Redis and other languages (Swift, PHP, JavaScript, and more). On the front end, I have experience with both Rails' native toolset and ReactJS, Next.js, and React Native. I also have experience with platform-native toolsets, such as SwiftUI, to deliver applications that feel intrinsically part of the user’s mobile experience. I've worked on projects of various sizes, from scheduling and booking software for a major tech training company to systems that enable TV distributors to sell thousands of hours of programming worldwide. Ideally, I'm looking to work on products with which I can feel personally invested – an exciting product or tech-for-good project would definitely suit me better than a fintech role.

Web Developer focusing on the Frontend and Rails

An Interdisciplinary Learner I'm Hao Chen, a web developer and historian based in Berlin. My interest in web development began when I attended a digital humanities workshop during my studies. I realized that in order to reach more people, high-quality content needs to be supported by modern technologies. I believe the web is the most powerful and universal medium, so I decided to give web development a try and ended up loving it. Self-taught Frontend I'm particularly drawn to the visual and interactive aspects of websites, so I started self-learning to become a frontend developer. Like everyone else, I started with the basics: HTML, CSS, and Javascript, and then I moved on to a framework: React. Trained Backend with Ruby on Rails After a year of self-learning, I attended the Le Wagon Berlin Web Development bootcamp, where I learned about Ruby and Ruby on Rails. I found these technologies enjoyable because they allow us to build full-stack applications efficiently and effectively. During the bootcamp's final projects week, my product pitch was selected, and I was chosen as the team lead for the final project team. We built a full-stack travel companion app using Ruby on Rails. Current tech stack After finishing Le Wagon Berlin in December 2022, I have been learning and building projects with React and NextJS. I am also gaining a deeper understanding of Rails and how it works with frontend frameworks. My current tech stack includes Tailwind CSS, SASS, React, NextJS, and Ruby on Rails. Skills: • Tailwind CSS • SASS • React • NextJS • Ruby on Rails Other Skills I am a historian through academic training, which has given me research and content-writing skills. Additionally, I have experience working as an assistant for two years, where I developed event management, interpersonal communication, and content editing skills. Skills: • Research • Content writing • Event management • Interpersonal communication • Content editing
