Senior Network & Cloud Engineer

Hi, I'm

Majid Ahangari

Senior Network & Cloud Engineer

Senior engineer with 16+ years across mission-critical enterprise systems, banking and payment infrastructure, telecommunications, and production operations — high availability, incident resolution, production monitoring, and operational continuity.

Hands-on with AWS, Microsoft Azure, Docker, Kubernetes, Terraform, Jenkins, Ansible, and CI/CD, and currently operating and supporting an AWS-hosted web platform across deployments, availability, and performance.

About Me

I am a senior engineer with more than 16 years of experience across mission-critical enterprise systems, banking and payment infrastructure, telecommunications, and production operations. I have deep experience in high-availability environments, incident resolution, production monitoring, troubleshooting, and operational continuity, backed by hands-on work with AWS, Microsoft Azure, Linux, Docker, Kubernetes, Terraform, Jenkins, Ansible, CI/CD, Python, and PowerShell.

I've built delivery pipelines and supported containerised deployments, and my current work includes operating and supporting an AWS-hosted web platform — covering server configuration, deployments, debugging, availability, and performance.

More recently, I've extended that into applied AI: I designed and deployed a Persian-language AI real estate assistant on Cloudflare Workers and Workers AI, grounding its responses in a live property catalog to handle customer questions and capture leads. I'm also completing an M.S. in Computer Engineering with AI/ML research in computer vision, object tracking, and reinforcement learning.
