Hire director / personal freelance Ruby on Rails developers in United Kingdom

Hi …. I’m Charlie. I am a Fractional CTO and Senior Ruby on Rails Engineer with 10+ years experience of building and scaling companies. I am equally comfortable discussing high-level strategic leadership or low-level technical problems. I have worked in, started and led multiple companies. Likewise, I have created, developed and maintained multiple web platforms. I recently led a major technological transformation at a group of companies, which is responsible for administering approximately 750 pension schemes. With £250M+ of assets under administration, 1,000+ clients and 30+ members of staff, it was always going to be a big challenge. When you also consider that almost everything was being done via email and phone calls, with 30+ disparate systems being used behind the scenes, the challenge went to a whole new level of complexity. I have written a number of articles about my experience and the key lessons learned.

I'm a full-stack Rails developer (although recent projects have concentrated on API-only backends with ReactJS front ends managed by different teams). I've been working with Rails for over 10 years (since version 3.x) and have specialised in making code bases 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 both with Rails' native toolset and with ReactJS, Next.js and React Native. I also have experience of platform-native toolsets such as SwiftUI to deliver applications that feel intrinsically like 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 allowing TV distributors to sell thousands of hours of programming all over the world. 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.
