What I'm looking for

I seek a security-focused engineering role where I can build secure cloud-native applications, perform threat modeling and vulnerability remediation, work in Agile teams, and grow into leadership while driving compliance and automation.

I am a cybersecurity-focused software engineer with experience building secure frontend and backend systems, cloud infrastructure, and automated CI/CD workflows. I have designed and deployed secure microservices, migrated access controls (RBAC to ABAC), and mitigated critical vulnerabilities while applying standards like NIST, ISO 27001, and OWASP.

My background spans security research (UAV protocol fuzzing, threat modeling), product and UI engineering for high-scale applications, and hands-on use of security tools (OWASP ZAP, SonarQube, Splunk). I collaborate in Agile teams to deliver secure, compliant, and performant solutions across full-stack and cloud environments.
