What I'm looking for

I'm looking to keep building reliable, high-availability infrastructure through observability, incident response, automation, and ownership of availability and latency targets.

At Devabit, I own availability and performance for multi-server Linux infrastructure supporting high-traffic web applications. I tune Apache, NGINX, MySQL, PHP, and Redis, define service targets, and turn recurring incidents into runbooks.

Previously at LvivIT, I optimized Linux production environments for high-traffic WordPress applications, automated deployments through CI/CD pipelines, and resolved complex server-side issues against demanding SLAs.

At Provectus, I monitored cloud-native AWS and Azure infrastructure, including Kubernetes clusters, VPCs, and load balancers. I used Bash and Python automation, led incident bridge calls, and restored services through L1/L2 troubleshooting.
