$ whoami_

I'm Rory, a Senior Software Engineer with over years of experience building and maintaining web applications and backend systems.

I work primarily with TypeScript across frontend and backend, with experience in Angular, Node.js, and JavaScript-based platforms. I'm comfortable owning features end-to-end in long-lived, production systems and improving existing codebases under real-world constraints.

Quality Assurance & Testing

Testing Strategy: Implemented multi-tier testing suites, including Cypress component testing, unit tests, and E2E flows to guarantee stability.
CI Integration: Embedded automated testing into deployment pipelines to catch regressions before they reach production.

Interests & Hobbies

I produce music released across major streaming platforms and it's one of my favourite long-term creative outlets. I'm always happy to talk about sound design, signal chains, or the overlap between synthesis and logic.

Electronic Music Production

I experiment with game mechanics and indie development on itch.io. While they won't be winning any awards, the process of managing game states and assets is a great sandbox for technical problem-solving.
