• Resolved an average of 95 Tier 1 and Tier 2 tickets per week with a 76% first-contact resolution rate, reducing escalations to senior engineers by 40% over two quarters, using Jira Service Management.

  Jira Service Management · 95 tickets/week, 76% FCR, 40% fewer escalations

• Provisioned, audited, and deprovisioned user accounts for 520 employees across a single Active Directory domain, cutting orphaned account count from 87 to 0 ahead of an annual security audit.

  Active Directory · 520 users, 87 → 0 orphaned accounts

• Migrated 310 user identities from on-prem LDAP to Okta SSO over 6 weeks with zero authentication outages, coordinating cutover communications through Slack.

  Okta, Slack · 310 users, 6-week migration, 0 auth outages

• Authored 18 runbook articles in the internal knowledge base covering password resets, VPN troubleshooting, and printer provisioning, deflecting an estimated 28% of repeat Zendesk tickets within 90 days of publication.

  Zendesk · 18 articles, 28% ticket deflection in 90 days

• Maintained 99.7% uptime across a fleet of 14 on-prem Windows Server 2019 file and print servers supporting 650 end users, responding to and resolving 3 P1 incidents within a 2-hour MTTR target.

  Windows Server 2019 · 99.7% uptime, 650 users, 2-hour MTTR

• Reduced mean time to resolution for account-lockout tickets from 3.5 hours to 45 minutes by creating a self-service unlock workflow in Okta, saving the helpdesk an estimated 6 hours of manual effort per week.

  Okta · 3.5 hrs → 45 min MTTR, 6 hrs/week saved

• Standardized endpoint imaging and software deployment for 200 Windows laptops using documented runbooks, cutting new-hire setup time from 4 hours to 90 minutes and reducing setup-related Zendesk tickets by 55%.

  Zendesk · 200 endpoints, setup time 4 hrs → 90 min, 55% fewer tickets

• Compiled and presented a monthly ticket-trend report in Excel for IT leadership, identifying the top 5 recurring issue categories and enabling targeted runbook creation that reduced those ticket types by 33% over one quarter.

The Sysadmin Bullet Formula: Verb + System/User Context + Outcome + Tool

Every bullet should answer: what broke (or needed maintaining), what you did about it, and what improved as a result. The verb matters — sysadmin verbs are operational: Resolved, Provisioned, Hardened, Documented, Automated, Escalated, Migrated, Audited. Avoid vague verbs like 'Assisted with' or 'Helped manage.'

The system or user context grounds the bullet in real infrastructure work. Name the environment: Active Directory domain, Okta tenant, Zendesk queue, on-prem server fleet, or hybrid network. This specificity separates a sysadmin bullet from a generic IT bullet.

The outcome must be measurable. Sysadmin metrics live in four buckets: (1) ticket volume or resolution speed (e.g., MTTR, first-contact resolution rate), (2) uptime or availability percentages, (3) user or endpoint counts affected, and (4) time saved through automation or self-serve deflection. Pick whichever bucket fits the work — but always include a number.

Role-Specific Patterns: Tickets, IAM, Runbooks, and Uptime

Sysadmin work clusters into four workstreams, each with its own bullet shape:

**Ticket triage and resolution:** Lead with the queue size or MTTR improvement. Name the ticketing platform (Zendesk, Jira Service Management). Show that you closed tickets, not just touched them.

**Identity and access management (IAM):** Provisioning, deprovisioning, and auditing user accounts in Active Directory or Okta is core sysadmin territory. Bullets here should name the directory, the user count, and a compliance or audit outcome.

**Runbook and knowledge base authorship:** Sysadmins who document well reduce repeat tickets. Bullets should show how many articles you wrote and the deflection or call-avoidance rate that followed.

**Uptime and incident response:** Own the availability number. If you maintained a server fleet or network segment, state the uptime percentage and the user or endpoint count it covered. If you led an incident bridge, show MTTR.

Avoid bullets that could belong to a software engineer or DevOps role — sysadmin bullets are about operational stability, user enablement, and documented repeatability, not deployment pipelines or container orchestration.

Metrics That Belong on a Sysadmin Resume (and How to Estimate Them)

If you don't have exact figures, use honest ranges or approximations you can defend in an interview. Common sysadmin metrics include:

- **Ticket volume:** 'Managed 80–100 tickets/week' or 'Reduced open ticket backlog from 200 to 45 within 60 days' - **MTTR (mean time to resolution):** 'Cut average resolution time from 4 hours to 90 minutes' - **First-contact resolution rate:** 'Achieved 78% FCR on Tier 1 hardware and account issues' - **User or endpoint scale:** 'Supported 400+ end users across 3 office locations' or 'Managed 600 Windows endpoints' - **Uptime:** '99.6% uptime across on-prem file and print servers over 12 months' - **Self-serve deflection:** 'Published 22 knowledge base articles that deflected an estimated 30% of repeat password-reset tickets'

Pick metrics that reflect YOUR scope. A sysadmin at a 50-person company and one at a 2,000-person enterprise will have different numbers — both are valid as long as they are accurate.
