Later, replaced NewRelic with Datadog.* In 2020, migrated from YOTTAA for content delivery and acceleration to using Azure Front Door and Azure Web Application Firewall, resulting in a 37% YoY cost reduction.* In 2021, implemented a custom solution to integrate OneLogin with our OpenVPN server to implement MFA.Key Technologies: WordPress, MySQL, MariaDB, CentOS Linux, Apache HTTPD, HAProxy, YOTTAA, Terraform, Ansible, GitHub, Sentry, NewRelic, Datadog, OneLogin, Microsoft Azure, Azure DevOps, Azure Front Door, Azure WAF, OpenVPN.
