Rehan Ahmed

Hello, and thank you for visiting!

I’m Rehan Ahmed, a seasoned Messaging and Security Administrator with over 15 years of proven experience supporting enterprise environments. Currently, I work as an Enterprise Systems Administrator at JPMorgan Chase, where I lead efforts on heritage First Republic Bank M&A integrations, email migrations, and domain cutovers.

My expertise lies in managing and optimizing hybrid Exchange environments (Exchange 2016 and Microsoft 365), automating workflows with PowerShell, and building secure, scalable systems. I’ve designed, integrated, and architected solutions that balance reliability, performance, and practical design patterns—especially in fast-paced, high-stakes environments.

I’m highly proficient with PowerShell, REST APIs, and Microsoft Graph, enabling me to extend functionality beyond out-of-the-box tools. From streamlining operations to creating automation pipelines and guiding teams through tool adoption, I focus on efficiency, flexibility, and robust documentation.

Above all, I’m passionate about solving complex challenges and enabling teams to do their best work. I believe real progress comes through continuous learning, collaboration, and a commitment to helping others succeed. To me, leadership isn’t about titles—it’s about showing up, staying curious, and empowering those around you.

If you’re exploring innovative projects in infrastructure, messaging, or systems engineering—or simply want to connect—feel free to reach out.
