What I'm looking for
I am a driven Cybersecurity Analyst and DevOps Engineer with 5+ years securing web applications, automating cloud infrastructure, and strengthening system resilience through penetration testing and SOC monitoring.
I have conducted over 120 penetration tests and monitored more than 1,200 monthly security events using SIEM, EDR, and XDR tools, improving detection and response capabilities while integrating security gates into CI/CD pipelines.
My technical toolkit includes Python scripting, Java/Springboot, Django, Docker, Terraform, Ansible, AWS and Azure; I balance secure development and defense operations to reduce risk and accelerate delivery.
I author technical security publications, contribute to vulnerability research, and deliver practitioner-focused training—seeking a remote cybersecurity or DevSecOps role to help organizations build secure, scalable systems.
