Profile
IT professional with 16 years of experience across cloud infrastructure, DevOps operations, backend development, mobile apps, and AI-driven automation. Currently working as an IT DevOps Support Engineer at National Broadband Ireland. Previously a Cloud Support Engineer II at AWS (CloudFront SME) supporting global enterprise customers.
I’m currently enrolled in a part-time MSc (Negotiated Learning) at University College Dublin (from Sep 2025), and I’m turning each module into published notes + small demos on this site.
I build practical products and tools: a civic-tech parking violation reporting app that processed 440,000+ citizen reports, a RAG-based troubleshooting assistant over my technical knowledge base, and newer prototypes like VideoTranslate (S3 → AWS Batch + Whisper subtitles) and ArgumentLab (YouTube → vector DB → argument exploration).
Verified certifications: Credly profile.
