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.
