Learn how we eliminated post-deployment network issues in a live trading environment by building a CI/CD pipeline for network config. We use a full virtual replica of our network to test every change against real traffic patterns and simulated failures, before it ever reaches production. The result: faster, safer, zero-touch deployments with no out-of-hours surprises. This talk shares our tools, process, and lessons learned building finance-grade network reliability without bureaucracy or fear.

David has always been involved in networking to some degree, but from different angles: Systems, Support, Development, Automation, and Infosec. David likes working on the big-picture, global network architecture and new PoPs/DCs, but also getting into the detail of anything going over the wire (protocol, formats, payloads).
Damian Krogul is a seasoned Site Reliability Engineer with deep expertise in networking, automation, and large-scale infrastructure operations. He currently focuses on designing and maintaining resilient, high-performance systems across hybrid environments, blending bare metal, cloud, and automation tooling like Ansible and Terraform.
