What I'm looking for

I am looking for a challenging role in a dynamic organization that values innovation and offers opportunities for professional growth.

My journey has been marked by a commitment to excellence in troubleshooting and resolving complex network issues, ensuring that service level agreements are honored and customer satisfaction is achieved. I have successfully designed and implemented network solutions from scratch, demonstrating my ability to lead projects and deliver results.

Throughout my career, I have worked with various firewall platforms including PaloAlto, Fortinet, and Checkpoint, gaining hands-on experience in managing network security operations. My role as an Architect at Carl Zeiss has allowed me to refine my skills in design, configuration, and migration of network systems while collaborating with cross-functional teams to enhance network performance and security. I am passionate about leveraging my expertise to drive innovation and improve organizational efficiency.
