As a Cloud & DevOps Engineer, I help companies build reliable cloud infrastructure, DevOps platforms, infrastructure automation, and highly available systems using AWS, Kubernetes, Terraform, CI/CD, and modern security and monitoring practices. Today, I also help teams adopt AI-assisted development tools, including Claude Code and automation agents, in a practical, secure, and production-ready way.
Modern DevOps is no longer only about infrastructure, pipelines, and servers. Teams are now building faster than ever with AI coding assistants, autonomous workflows, and vibe-coding tools. But fast AI-generated prototypes often need expert cloud, DevOps, security, and architecture work before they can become stable production systems.
This is where my 20 years of hands-on IT experience, recognition by Upwork as an Expert-Vetted professional, and being featured in Upwork's Success Stories become real advantages.
I am also the author of The Cloud DevOps Engineer's Guide, where I showcase the proven methodologies I apply to help organizations design, automate, secure, and scale resilient, cloud-native infrastructures.
My core expertise includes:
✔️ Cloud infrastructure on AWS, Azure, GCP, and DigitalOcean.
✔️ Kubernetes, Docker, Helm, and production container deployments.
✔️ Terraform, Ansible, Infrastructure as Code, and environment automation.
✔️ CI/CD pipelines with GitHub Actions, GitLab CI, Jenkins, and other tools.
✔️ Claude Code, OpenClaw, and AI-assisted development workflow adoption.
✔️ AI-generated and vibe-coded application review, stabilization, deployment, and scaling.
✔️ Large codebase navigation, refactoring support, and development automation.
✔️ AI-assisted test generation, documentation workflows, and code review support.
✔️ Security reviews for code, cloud infrastructure, secrets, permissions, and deployments.
✔️ Custom AI agents for engineering, DevOps, monitoring, and code review workflows.
✔️ 24/7 monitoring, observability, alerting, logging, and incident-response automation.
✔️ DevSecOps, secure pipelines, automated checks, and production hardening.
✔️ Cost optimization, scalability, reliability, and high availability.
✔️ Linux, Bash, Python, networking, databases, distributed systems, and cloud-native architecture.
My experience across AWS, Azure, GCP, Kubernetes, Terraform, Docker, CI/CD, monitoring, and security allows me to work not only as a DevOps Engineer but also as an AI-Augmented Platform Engineer, helping teams modernize how they build, deploy, review, secure, and operate software.
Whether you need to modernize your infrastructure, adopt Claude Code, explore OpenClaw-based automation, build custom agents, review an AI-generated codebase, stabilize a vibe-coded application, or deploy, secure, and scale your prototype in the cloud, I can help you move from idea to production with a secure, stable, and scalable setup.

I provide affordable cyber security solutions to startups, small and medium-sized businesses, non-profits, and other organizations. I organizations that need improved security but don't have the budget to support an enterprise level. I work with these companies to create a security solution that is both affordable and effective. In today's world of ever-increasing cyber threats where small businesses are targeted more frequently, it is vital that these companies have IT Security systems in place. Statistics show that nearly half of small companies that suffer a cyber breach never recover.
