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.
