At the Republic of Korea Army, I carried out security audits and vulnerability assessments across four controlled network zones, documenting and tracking findings through remediation. I also supported IT and network operations across headquarters and four companies.
I built Python call-sign detection on an isolated system, reducing response times from 10+ minutes to under one minute and missed responses to 0%. I also automated inventory and repair workflows for 500+ IT assets.
At Black Box Network Services, I was promoted to QA/QC team lead within three months and led a three-person team that cleared 100+ backlogged inspection tickets. On Paladinscat.com, I designed and operated production architecture and security controls, including Cloudflare allowlisting, VPN-only SSH, and Keycloak/OIDC authorization.
