Gregory Shiel | Business Analyst & System Tester

About

I'm a Business Project/Process & System Tester for Siemens Digital Industries Software, working in software quality assurance within a global engineering environment.

My degree in Music, Media and Performance Technology from the University of Limerick gave me a strong foundation in project delivery, technical problem-solving, and cross-functional collaboration. The scope of my work within Siemens focuses on test management, development / definition and testing. My role places a specific focus on audit compliance and detailed accurate documentation from reports through tracking matrixes.

I've built and led teams from the ground up. From founding an events company, presiding over a university society, and managing projects in both commercial and educational settings.
