I build secure, automated data center and ISP network infrastructure.
BoliviaWhat I'm looking for
At Cisco Systems, I designed and optimized enterprise data center fabrics using Cisco NDFC, upgraded Nexus Dashboard Orchestrator across five sites, and resolved 7,000+ fault tickets across multi-pod deployments.
I've delivered secure, scalable network architectures for North American and international clients, including ISP core networks, MPLS data center interconnectivity, and banking-network migrations. I also use Ansible, Bash, and Python to automate operations, including work that improved efficiency by 50%.
My work spans NGFW deployments, CVE remediation, DDoS mitigation, routing and switching, and local LLM-based NetOps assistants using Ollama and RAG. I'm open to remote worldwide full-time or B2B contractor opportunities.
