Scrum Master at State Farm Mutual Automobile Insurance Company

Andrea Orth

I've worked in IT for over 25 years at the same Fortune 50 company. I started out as a mainframe developer working with COBOL and DB2. Early in my career I worked with the GenevaERS product and came to understand the scalability and efficiency the mainframe provides. During my career, I've had had different roles including Scrum Master and Product Owner. I have served as the Vice Chair of the GenevaERS Technical Steering Committee sponsored by the Linux Foundation's Open Mainframe Project since the project's inception. Among other things, I have acted as Scrum Master, run communications for the project, provide customer input and direction, and provided an independent voice. I was recently appointed the Chair of the project. Hobbies include collecting hobbies and caring for my over 30 pets.

Joe Bostian

I've been an open source and middleware developer for most of my career. I focus on backend and infrastructure development, but have been known to stray into front end interfaces when necessary. IBM Z is my platform of choice, but I also am spending an increasing amount of time working in the cloud. Learning new stuff is what makes all of this fun.
