Networking and infrastructure
I like networking because configuration actually matters there. It is one of the clearest places to see how systems behave when the details are right or wrong. Most of my work here has been around routing, switching, access control, Linux networking, and infrastructure tooling.

CCNA Packet Tracer Branch Network Lab
Packet Tracer reconstruction of Jeremy's IT Lab's introductory branch topology, connecting New York and Tokyo segments through routers, firewalls, switches, servers, and an attacker host.
Cisco Packet Tracer / CCNA / Cisco 2911 / Cisco 2960 / ASA 5505
- recreated the two-branch New York and Tokyo network layout from the tutorial diagram
- placed and labeled Cisco 2911 routers, 2960 switches, ASA 5505 firewalls, PCs, servers, and attacker laptop
- used Packet Tracer auto-cabling workflow to assemble the end-to-end WAN path quickly
- built a clean baseline lab for later CCNA configuration and troubleshooting practice

Cloud & DevOps Infrastructure Automation
Infrastructure-as-code project automating secure cloud provisioning, deployment workflows, and observability.
Kubernetes / Terraform / Ansible / AWS / Prometheus / Grafana / Linux
- automated AWS provisioning with least-privilege IAM and VPC isolation
- Kubernetes deployment workflows with rollback-safe releases
- Prometheus/Grafana monitoring and alert visibility
- Git-driven CI/CD automation and server hardening
