Entry-level Network Engineer resume example

• Performed read-only checks on customer connectivity tickets, comparing TCP/IP symptoms with interface status, routing tables, and DNS answers; attached reproducible tests so the supervising engineer could choose the next diagnostic step.
• Prepared VLAN access-port changes from an approved template, checked the device and port against the inventory, and ran the agreed connectivity checks after a senior engineer applied the change; recorded the result and rollback reference in the ticket.
• Compared BGP peer states and OSPF neighbors before and after a scheduled maintenance window; flagged a missing adjacency to the owner rather than resetting a live session without approval, and verified the recovery evidence with the NOC.
• Wrote a Python report that reads exported interface and IP address records, checks duplicate assignments, and produces a review list; kept credentials and configuration writes out of the script and added fixtures for missing fields.
• Within the assigned scope, compared BGP route advertisements before and after a peering change, checked prefix filters and maximum-prefix limits, and rehearsed withdrawal without affecting unrelated peers.
• Within the assigned scope, owned a BGP network-design validation using isolated routing fixtures, resolved asymmetric paths and completed redundancy tests before the migration review.
• Within the assigned scope, built Python log-analysis checks using REST inventory data, reduced root-cause-analysis preparation from 50 to 20 minutes and published the capacity-management worksheet.

• Assisted a data-center technician with rack and patch-panel documentation; matched cable labels, switch ports, and circuit identifiers during a supervised walk-through and returned discrepancies for owner review.
• Annotated SNMP and syslog alert examples with the affected interface, time, and maintenance context; distinguished a planned shutdown from an unexplained flap and submitted the event timeline for the mentor’s triage review.

• Built a containerlab topology with FRRouting, eBGP between lab autonomous systems, and OSPF inside the test network; drew the address plan and checked expected routes before adding IPv6.
• Injected a wrong prefix filter and an MTU mismatch, then diagnosed each with routing output and tcpdump; kept the failed checks and corrected configuration together so a reviewer could reproduce both the problem and the fix.
• Versioned Python IPv4/IPv6 TCP checks and Ansible configuration previews in Git; ran them against a mock REST API inventory, rejected missing interface IDs, and captured the corrected fixture and passing output for repeatable lab review.
• Owned the recovery rehearsal using an isolated test account, resolved a missing permission prerequisite and completed the restore without changing the working baseline.
