I'm a full stack developer with 5 years of production experience — not side projects, actual shipped systems.
I work daily in Ruby on Rails, C# .NET, and Flutter. On the Rails side that means multi-tenant SaaS, POS systems, Sidekiq jobs, and API-heavy backends. On the .NET side, WinForms, WPF, WinUI 3 desktop apps, QuickBooks SDK, hardware integrations.
Right now I work remotely for a Manchester eCommerce company building shipping automation and warehouse tools. Amazon SP-API, Shopify, eBay - I've integrated them all in production.
Clean code. Honest timelines. I actually reply.
