About

Gregory Shiel

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

My Bachelor of Science 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.

Independent - On hold

Local Agentic AI Home Server

Researched Apple's MLX and Meta's Llama to decide how best to run an agent on a headless MacBook Pro. Ran Claude Code as a 24/7 remote-access agent over SSH and Tailscale, running intense agent processes on local machine power while working independently and remotely (e.g. building and maintaining this website). The machine failed in September 2026; repair pending.
