At GuardianLab LLC, I architect, deploy, and administer security infrastructures across client environments. I also evaluate enterprise tools through proof-of-concept work and design lab-based security architectures.

At International Bank of Azerbaijan, I monitored and investigated security alerts across SIEM, XDR/EDR, DLP, WAF, secure mail gateways, and firewalls. I carried out incident response actions and documented root-cause analysis and remediation workflows.

At Code Academy, I mentored cybersecurity students in incident analysis, system hardening, and network fundamentals. Earlier, I worked as a Drilling Monitoring Engineer at Shelf Oil and GasTechnology and SOCAR, and as a Well LogAnalyst at SOCAR.
