01 · About

Grounded in identity, access, and hybrid cloud support

I'm an IT professional with a background in Networking and IT Security, with a strong focus on cloud technologies, identity, and cybersecurity. I'm particularly interested in Cloud Support and Identity & Access Management (IAM), and I've built hands-on experience working with Azure, Entra ID, and Intune across both academic and professional environments.

In my current role as a Service Desk Analyst at Aecon Group Inc., I support secure and efficient IT operations within hybrid environments — user provisioning, access controls, MFA, and troubleshooting authentication and synchronization issues across on-prem and cloud systems, while meeting SLA-driven enterprise support requirements.

I've taken a hands-on approach to developing my technical skills, contributing to Azure-based system projects and running a Man-in-the-Middle (MITM) attack simulation to better understand network vulnerabilities and real-world security risks. Beyond the technical side, I bring strong communication and leadership experience through nine-plus years of mentoring youth — which has sharpened my ability to explain complex concepts clearly and support people through high-pressure situations.
