Cloud / DevSecOps Engineer

Building secure, scalable cloud platforms and automation systems on AWS with a focus on reliability, security, and developer productivity.


🧭 Summary

Cloud and DevSecOps engineer focused on designing and operating production-grade infrastructure. Experienced in infrastructure as code, CI/CD automation, containerized workloads, and security-first cloud architectures.

Strong emphasis on building repeatable systems that scale across environments and teams.


🧰 Core Expertise

Cloud & Infrastructure

  • AWS Cloud Architecture (multi-account, multi-AZ design)
  • Infrastructure as Code (Terraform, modular patterns)
  • Networked cloud systems (VPC design, IAM architecture)

Platform Engineering

  • CI/CD pipelines (GitHub Actions, CodePipeline)
  • GitOps workflows and automation strategies
  • Developer platform enablement and workflow optimization

Security Engineering (DevSecOps)

  • IAM design and least-privilege access models
  • Policy-as-code enforcement
  • Vulnerability scanning (Trivy, Checkov)
  • Secure pipeline design and hardening

Containers & Orchestration

  • Dockerized workloads
  • Kubernetes fundamentals and deployment patterns
  • Cloud-native application delivery

🏗️ Featured Work

Enterprise DevSecOps CI/CD Platform

  • Designed automated CI/CD pipelines with integrated security scanning
  • Implemented Terraform-based infrastructure provisioning
  • Enforced policy-as-code checks across deployment stages
  • Built reusable pipeline patterns for scalable delivery

Infrastructure as Code Framework

  • Modular Terraform architecture for AWS environments
  • Standardized environment provisioning (dev/staging/prod)
  • Reduced manual configuration drift through automation

🧪 Engineering Principles

  • Infrastructure is software
  • Security is embedded, not added later
  • Automation over manual processes
  • Repeatability and consistency across environments
  • Systems designed for scale and failure tolerance
