Ruby on Rails Software Development, Technical Documentation

I'm a Senior Software Engineer with 4 years of Ruby on Rails experience, equally comfortable writing clean backend code and the documentation that explains it. On the development side, I specialise in building reliable, scalable backend systems using Rails, ActiveRecord, Sidekiq, PostgreSQL, and RSpec. I've grown from intern to Senior Engineer by delivering high-quality solutions and adapting quickly to new challenges. I also bring hands-on experience with technical documentation - API references, onboarding guides, and internal runbooks. My engineering background means I can document systems accurately without needing things explained to me, and I understand what makes documentation genuinely useful for both technical and non-technical audiences. Whether you need a backend developer to build and scale your product, or someone to document it clearly for your users and team - I can do both, and the overlap between the two is where I add the most value.
