You inherit this application at month 8. * Federal cloud authorization boundary work (FedRAMP or equivalent); Entra ID / Azure AD; PIV or CAC authentication. * Splunk or comparable SIEM; Zero Trust or CISA directive compliance work; a Linux, cloud, or security certification (RHCSA, RHCE, Azure Administrator, Security+, or equivalent). ## Description Kosma modernizes a Learning Management System for a U.S. federal agency. You build, secure, and operate the platform below that system for the full 12 months: the Linux estate, the database and cache layer, the cloud migration, identity federation, security hardening, monitoring, disaster recovery, and release management. A Moodle subject matter expert owns the product decisions for the first eight months - then hands you operational ownership of the application. You do not need to arrive as a Moodle expert. You do need to be a strong platform engineer who owns that application by the end of the year. What you will do * Build and operate the Linux estate behind a production web application; migrate the platform into a Government-authorized cloud. * Own the database and cache layer (MariaDB/PostgreSQL, Redis): configuration, tuning, backup, restore, and performance against defined page-render targets. * Build single sign-on with OIDC (SAML 2.0 where required), federated with an enterprise directory, smart-card credentials, and MFA; own platform-layer access control. * Harden against a defined federal control framework and keep the audit evidence; run monthly vulnerability scans, a documented patch cadence, and central logging, monitoring, and alerting. * Manage releases through CI/CD. You hold the final release authority; the Moodle expert defines application rollback criteria. * Design and test disaster recovery against defined objectives; keep uptime against a contractual business-hours commitment; control change inside Government blackout windows. * Run the reporting infrastructure - the Moodle expert designs the reports, you make them run. * Take operational ownership of the Moodle application during months 6 to 8, then operate, patch, release, and repair it alone. ## Related Videos - [Our journey with Spring Boot in a microservice architecture](https://www.wearedevelopers.com/videos/511-our-journey-with-spring-boot-in-a-microservice-architecture) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Starting business without breaking the bank: Self hosted OSS productivity ecosystem](https://www.wearedevelopers.com/videos/1219-starting-business-without-breaking-the-bank-self-hosted-oss-productivity-ecosystem) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) - [Hacking MSSQL on Cloud.
