Introduction

I am a site reliability engineer with a strong background in network engineering and Unix administration. I bring 20 years of industry experience to the table, along with a passion for technology.

My latest work centers on developing processes that address systemic and cultural challenges within organizations to enhance reliability, foster alignment and ensure compliance. I approach technical leadership with a warm affirming communication style, firmly believing that individuals thrive in an atmosphere where their contributions are appreciated, and where mutual respect among peers is upheld.
