Software Engineer

I’m currently a Software Engineer Manager with Microsoft’s C+E Security group. I lead a team of engineers responsible for a new Azure security service that analyzes memory dumps from Azure VMs and Azure services to detect signs of malware compromise. I began my career as a Software Engineer working for Unisys Corporation in 2000, responsible for network protocol driver systems that allowed Unisys mainframe operating systems to leverage Windows environments for networking support. I discovered security while working on a TCP/UDP port filtering feature designed to help protect Unisys servers from DoS attacks, and by 2005 joined Microsoft in a software engineer role to help support Microsoft’s own security monitoring and defense efforts. After a variety of roles developing security services and tools helping Microsoft defenders monitor and protect against attacks, my focus has returned to building security products and services that help customers detect and respond to threats.

I’m eager to learn new skills and technologies, and am excited to find ways my experience might help others. So contributing after-hours to help the GEN team was a natural fit for me. In my spare time I enjoy training for and running in marathons, and spending time with my wife and our dogs. ”

She’s formally presented to numerous organizations including SARC and ORLA and engaged in countless informal conversations.

She holds a BS in Psychology from Portland State University, a BS in Merchandising Management from Oregon State University, and a JD from Willamette University. She is a member of the Oregon State Bar. Currently, Andrea is writing policy guidelines to set aside victims’ criminal convictions.
