I build and secure cloud infrastructure — AWS, Linux systems, Docker deployments, and automated security operations with production-grade reliability.
Core Expertise
Building and managing cloud infrastructure, Linux servers, and containerized deployments with production-grade reliability.
Embedding security into every layer — from identity management to runtime monitoring and compliance.
Automating workflows, building APIs, and maintaining CI/CD pipelines for reliable production systems.
Selected Work

About
I approach infrastructure and security from an operator's perspective — Linux systems, cloud infrastructure, and network security. Every system I build starts with threat modeling — identifying attack surfaces, enforcing least-privilege access, and ensuring data integrity at every layer. Security is not an afterthought; it is the foundation of reliable architecture.
My work sits at the intersection of cloud infrastructure, systems administration, and operational security. I build APIs that handle production traffic with predictable performance, deploy infrastructure through code that can be audited and versioned, and integrate security scanning into CI/CD pipelines so vulnerabilities are caught before they reach production.
I believe in automation over manual process. From infrastructure provisioning with Terraform to automated compliance checks and container scanning, I eliminate human error by codifying operational procedures. This approach reduces incident response time and ensures consistent, reproducible deployments across environments.
Whether it is hardening a Kubernetes cluster, implementing zero-trust networking, or designing rate-limited API gateways — I build systems that are secure by default, observable in production, and resilient under load.
