Experienced Microsoft 365 support engineer delivering reliable enterprise collaboration and identity solutions.
United StatesI am a dynamic, results-driven IT professional with extensive experience supporting Microsoft 365, Microsoft Teams, and identity solutions for enterprise customers. I consistently deliver positive outcomes through strong analytical skills, attention to detail, and a commitment to deadlines.
In my current role at Microsoft I provide Tier 3 support for Microsoft Teams and manage critical incidents for S500 enterprise clients, troubleshooting complex collaboration, identity, and compliance scenarios across hybrid and cloud environments. I coordinate with TAC, OEMs, and cross-functional teams to resolve persistent failures and improve service health.
Previously I supported Office 365 workloads and identity systems in fully remote roles, troubleshooting Exchange Online, SharePoint, OneDrive, and Azure AD/Azure AD Connect, and administering environments using PowerShell. I have a background in telecommunications and frontline technical support, giving me strong customer-service instincts and the ability to explain technical issues clearly to non-technical users.
I hold Microsoft certifications (Azure AI Fundamentals; Security, Compliance, and Identity Fundamentals; Microsoft 365 Fundamentals) and have contributed to projects such as Microsoft Intune translation reviews and internal knowledge bases. I am motivated to grow within an innovative IT environment and to continue improving both my technical and language skills.
