What I'm looking for

I'm seeking a meaningful opportunity where I can apply my knowledge of server support and system administration to solve technical challenges, meet business needs, and successfully complete deadline-driven projects.

At Sysmex America, Inc., I installed and configured Linux servers and supported production and non-production environments. I also automated provisioning, patching, health checks, and recovery workflows with Ansible, Bash, and Python.

During platform modernization, I supported application migrations to AlmaLinux and database movement into AWS RDS, contributing to a 30% reduction in operating costs. I also strengthened patch and vulnerability processes through Red Hat Satellite, Nessus remediation, and documented change validation.

Previously, at Dfuse Technology, targeted fixes contributed to a 25% improvement in system performance. At Yelp Inc., I isolated production bottlenecks, implemented load balancing, and optimized configurations to improve application response time by 40%.
