What I'm looking for

I'm looking to take ownership of complex platforms, modernise legacy systems, and turn business needs into practical technical delivery plans. I value autonomy, strong engineering processes, and teams that use AI-assisted workflows responsibly.

I've taken full ownership of Stinkyink's undocumented Rails e-commerce platform as its sole developer, supporting the storefront, internal admin system, and Axis Diplomat warehouse integration.

I led the application upgrade from Rails 5 to Rails 7 and helped move delivery from self-managed Kubernetes to AWS ECS, resolving stability issues and establishing a GitHub Actions-based deployment pipeline. I also rebuilt local development tooling and expanded automated testing with RSpec, Cucumber, and Capybara.

Previously at AirPOS, I built point-of-sale software across payments, mobile, and cloud infrastructure, including integrations with Stripe, PayPal, Zettle, and SumUp. I bring a decade of full-stack experience, technical roadmap ownership, hiring input, and practical AI-assisted development workflows.
