What I'm looking for

I seek a role focused on reliability, cloud infrastructure, automation, and observability where I can reduce operational toil, mentor teams, and improve system availability.

I am a results-driven Linux and cloud engineer with extensive experience automating, scaling, and supporting large Linux environments across AWS, OCI, Azure, and hybrid infrastructures. I focus on reliability engineering, observability, CI/CD, and infrastructure automation to reduce operational toil and improve system performance.

I have engineered networking and cloud infrastructure components including DNS, DHCP, firewalls, load balancers, VNICs, EC2, RDS, ELBs, autoscaling, and IAM, and I deploy infrastructure with Terraform, Jenkins, Ansible, and CI/CD pipelines. I routinely build and analyze performance dashboards using Splunk, Grafana, and CloudWatch and have implemented large-scale patching and migration projects with thorough pre/post validation.

Throughout my career I have supported 24/7 production environments, participated in on-call rotations, collaborated with security and Tier 4 teams on complex incidents, and automated operational workflows using Bash, Python, PowerShell, Lambda, and Git-driven pipelines—delivering stable, high-availability systems in fast-moving environments.
