Rehan Ahmed

Hello, and thank you for visiting!

I’m Rehan Ahmed, a seasoned Messaging, Security, and Windows Administrator with over 15 years of enterprise experience in systems engineering, cloud infrastructure, and automation.

Currently, I serve as an Enterprise Systems Administrator at JPMorgan Chase, where I lead initiatives involving heritage First Republic Bank M&A integrations, email migrations, and domain cutovers.

My expertise spans Windows Server administration, hybrid Exchange environments (Exchange 2016 and Microsoft 365), PowerShell automation, and secure system design. I specialize in building scalable, reliable architectures that balance performance, resilience, and operational efficiency—especially in complex enterprise ecosystems.

I’m highly proficient with PowerShell, REST APIs, and Microsoft Graph, which I leverage to extend platform capabilities, streamline workflows, and automate repetitive tasks. From designing automation pipelines to mentoring technical teams, I focus on driving consistency, performance, and clarity through robust documentation and process optimization.

Beyond technical expertise, I’m deeply passionate about problem-solving, continuous learning, and empowering others. I believe real leadership comes from curiosity, collaboration, and helping teams thrive—not just holding a title.

If you’re exploring innovative projects in infrastructure, messaging, or systems engineering, or simply want to connect, I’d love to hear from you.
