AtriCure

IT security and infrastructure co-op, Mason, OH · –

Worked phishing triage, identity auditing, and security automation on the IT security team at a medical device company.

I spent the summer on the IT security and infrastructure team. After about two weeks of onboarding, the daily phishing queue was mine to work. Alongside it I designed and built the Cloudflare-to-Sentinel ingestion as a production Azure Function, and did audit work in Entra and Defender for Cloud Apps, most of it careful, one-item-at-a-time review rather than a single report.

  • Triaged 294 user-reported emails in Defender XDR and PhishER using SPF/DKIM/DMARC, header, sandbox, and KQL analysis; remediated with deletions, quarantine decisions, and blocks.
  • Designed and built a production Python Azure Function that brings Cloudflare Security Insights notifications into Microsoft Sentinel through Azure Monitor data collection rules.
  • Audited single sign-on configuration, SAML/OIDC protocols, and certificate status across the company's Entra enterprise applications, and reported the results to security leadership.
  • Configured KnowBe4 executive phishing reports and presented phishing-trend data at SecOps meetings.
  • Investigated unsanctioned cloud application use with Defender for Cloud Apps and KQL, and escalated findings to security leadership.
  • Supported identity reviews in Entra ID, Microsoft Graph, and Purview, and investigated sign-in alerts.

Graeter's

Shift leader, West Chester, OH · – present

Run the store as the on-site leader, usually without the store manager present.

Not security work, but a lot of the same habits: opening and closing on my own, counting cash and making deposits, sending people home early when sales don’t support the staffing, and handling the customer who is upset before it becomes a bigger problem. I also help train new hires and coach the team as we go.

  • Run store shifts as the on-site manager, directing two to three staff on weekdays and up to six at peak while prioritizing customer escalations, cash control, breaks, and real-time labor adjustments.
