01 — About

Building the infrastructure
the internet runs on.

I am a Cloud & Systems Engineer with a strong background in networking, telecom, cloud infrastructure, DevOps, SRE, and web application deployment. My experience connects the foundation of networks with modern cloud-native platforms, helping applications run reliably, securely, and efficiently in production.

I work with technologies such as AWS, Kubernetes, Docker, CI/CD pipelines, automation, monitoring, and infrastructure as code. I understand how web applications are deployed, scaled, monitored, and connected to the infrastructure behind them.

My focus is building reliable platforms for modern web services — from networking and cloud architecture to containers, observability, and production support.
