Cisco Certified Network Associate (CCNA) CompTIA Network+ Certified Network Engineering & Routing/Switching

Built a 6-stage Cisco Packet Tracer lab series across 3 routers and 4 switches, extending the topology with advanced routing and switching features at each stage.

Segmented traffic into 4 VLANs using 802.1Q trunking and inter-VLAN routing (Router-on-a-Stick), bundling switch uplinks with EtherChannel. Configured single-area and multi-area OSPF alongside EIGRP, verifying neighbor adjacencies, metric calculations, and routing tables via Cisco IOS show commands.

Implemented floating static routes to establish automatic path failover, ensuring traffic seamlessly shifts to a backup path during primary link degradation.

Hardened network infrastructure and device access via SSH v2, AAA/VTY line restrictions, and standard/extended Access Control Lists (ACLs) to enforce inter-VLAN traffic segmentation.

Deployed core network services, including dynamic DHCP pools and Port Address Translation (NAT/PAT), allowing private hosts to automatically receive IP addresses and securely reach outside networks. Cloud Infrastructure & DevOps Automation

Provisioned scalable AWS EC2 instances, custom VPC security groups, and key pairs using Terraform within a WSL2 (Ubuntu) environment, replacing manual console setups with modular, repeatable Infrastructure as Code (IaC). Automated Nginx web server deployment and configuration management using Ansible playbooks, dynamically injecting live server metadata into Jinja2-templated landing pages.

Resolved state drift following a local environment migration by running terraform import against live AWS resources, eliminating duplicate provisioning and preventing double billing.

Maintained end-to-end version control using Git across 59 commits, publishing architectural topologies, configuration scripts, screenshots, and troubleshooting READMEs in a public GitHub repository. Work Experience
