What I'm looking for

I seek senior security roles where I can lead cross-functional teams, drive security transformations, implement secure-by-design solutions, and advance vulnerability detection and incident response in an organization aligned with compliance needs.

I am a Security Architect with 10+ years' experience designing and implementing security solutions across IT and OT environments, migrating security stacks, and strengthening vulnerability and incident response programs. I lead and mentor security teams, deliver security awareness training, and implement controls aligned to ISO 27001 and NIS2.

My hands-on achievements include deploying TXOne Antivirus for OT, migrating Exabeam to Microsoft Sentinel, consolidating email and endpoint security into Microsoft Defender/EDR, and configuring Qualys VMDR for vulnerability management. I prioritize secure-by-design practices, automation, and cross-functional collaboration to reduce risk and improve operational efficiency.
