About Me

I am a DevSecOps Engineer and Cloud Security Engineer with over 3 years of experience designing, securing, and automating cloud environments across AWS, Azure, and GCP. My work focuses on integrating security into every phase of the software development lifecycle, from infrastructure provisioning to production deployment.

I have delivered secure and scalable solutions using Terraform, Kubernetes, Docker, Jenkins, and cloud-native security services, ensuring compliance with industry standards while maintaining high availability and performance. My expertise includes CI/CD pipeline automation, infrastructure-as-code, vulnerability management, and cloud security architecture. Over the years, I have delivered projects that blend security, compliance, and automation. From deploying a production-ready AWS EC2 website with hardened configurations, to setting up CloudTrail monitoring for real-time activity tracking and anomaly detection. I have led security implementations for PCI DSS and HIPAA compliance, ensuring cloud systems meet strict regulatory requirements. Additionally, I have executed technical threat simulation scenarios to uncover vulnerabilities and strengthen organizational security posture.

By combining deep technical expertise with a proactive, security-first mindset, I help companies reduce risk, accelerate deployments, and maintain compliance without slowing innovation. My approach ensures that your cloud infrastructure is secure by design, resilient under pressure, and ready to scale, giving your organization the confidence to focus on growth while I handle the security backbone.

If you’re looking for a security professional who can fortify your cloud infrastructure, streamline DevSecOps workflows, and ensure airtight compliance without slowing innovation, you're in the right place. I don’t just secure systems; I future-proof them.
