About

Gregory Shiel

I work as a Business Process/System Tester on the Software Testing/Hypercare Team at Siemens Digital Industries Software (for Interesource Group (Ireland) Ltd.), within a global finance tech engineering environment. I'm studying for a Master's of Science in Computer Science, Artificial Intelligence at the University of Galway (expected 2028).

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 as a student, presiding over a university society, and managing projects in both commercial and educational settings.
