Hello, my name is Carl Sebastian Marnewick
I'm a digital forensics specialist
Hi, hope you are having an amazing day! Enjoy reading a bit about me and how my journey started!
About Me
I'm Carl Sebastian Marnewick and I'm a Digital Forensics Investigator and Incident Responder
My love for IT was sparked by my grandmother, she gave computer lessons in the early 2000's where people were still learning how to use basic things such as Word and Excel. This is where I had my first ever experience with technology and where I grew to love it. As the years passed and I got older, my passion grew like a forest fire. I love learning new things and challenging myself. I work well in groups and have had my fair share of being a leader. One of my favorite quotes from Jack Welsch sums it up. “Before you are a leader, success is about growing yourself – when you become a leader, success is about growing others.”
