Hi, I'm Danny and I am an experienced Ruby on Rails developer and technical leader. Having worked with some of the best/most well known Ruby/Rails companies (most recently Cookpad for 5+ years), I have an detailed understanding of Ruby/Rails best practice, working at scale and what makes software development teams thrive. I have extensive experience with Ruby, Rails, Stimulus, JS, Tailwind, MySQL, Postgres, Kafka and numerous other technologies. I come with a long history of managing teams and projects, from smaller 8 person teams as EM/Lead Developer to 75 person engineering organisations. I can help you with: Ruby/Rails/JS development Levelling up your current team Developing/implementing your company best practices and documentation Managing your team (1-1's, career development) I am passionate about business and product development and enjoy working with product counterparts to develop roadmaps, conduct user interviews and scope projects. I am a well rounded individual who "gets things done".

I'm a web developer with over two decades of experience. I enjoy using Ruby and associated web development frameworks such as Rails. I'm interested in best-practice behaviour/domain-driven design, having suffered by both the absence of test suites and the diminishing returns of poorly designed/maintained ones. I'm passionate about clear and concise communication in all media. I have run my own freelance web development business since 2005. A career highlight was being Senior Developer for the team behind Comic Relief's 'On the Night' donations platform, which handled millions of pounds of donations in a few hours, via a highly available multi-region Cloudfoundry deployment on AWS.

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 to read, understand and maintain by teams. 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). 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.

I'm a Full Stack Ruby on Rails Developer, living and working in the UK. I've been a Ruby Developer since 2018, working in a range of different roles including startups, non-profits, and global engineering organizations. During these years, all of my positions have been remote, with most at remote-first organizations. I started my web development journey back in 2007, as a hobby, alongside my previous profession as a Mechanical Engineer where I managed £MM engineering projects in the oil and gas industry. I'm currently employed in a full-time Rails position but am open to interesting contract/freelance opportunities with a small/flexible time commitment of ~2 days per week.

Seasoned Rails developer. Currently training devs @ Shopify. Last dev role was Principal Developer where I managed product and led a small team of devs. I've built and delivered digital products (apps, websites, training and services) for worldwide brands and aspiring businesses. I've also built and sold products and agencies and freakin' love SaaS companies.

I’m a self-taught full-stack software engineer and library developer with a background in user experience design and accessibility. I have seven years of experience building and scaling high-performance Rails apps on the backend and frontend. I worked at Shopify for over four years — first on the Privacy Engineering team and then on Ruby and Rails Infrastructure. I also maintain a few open-source Ruby gems, including Phlex, Literal Enums, and Action State. I’m particularly interested in non-single-page-application frontend architecture in Ruby / Rails apps. I designed a framework for building UI components using object-oriented Ruby instead of a templating language and I’m also working on a specialised compiler to improve performance and make it possible to render differential updates.
