ENTERPRISE GRADE

Zero-Trust Enterprise Infrastructure & Centralized Auth

ASIX Higher Degree capstone: a full corporate infrastructure built from scratch to simulate a real company. Centralized authentication ran on a multi-master OpenLDAP cluster — two mirrored directory servers in active-active replication — backed by a MariaDB database. Debian clients were provisioned with roaming profiles, so each user’s data and session followed them to any workstation on the network. Both servers streamed automated, scheduled backups to an off-site NAS placed outside the internal perimeter, acting as a private-cloud vault for the whole infrastructure. High availability was engineered at the network edge: a watchdog script instantly promoted a standby router the moment the primary went down, keeping services online with zero interruption. The environment was hardened with a zero-trust posture (restricted file visibility, no exposed APIs, isolated services) and fully observed through Zabbix, with real-time alerts on network and service health.

ENTERPRISE GRADE

Autonomous Multi-Agent IT Orchestration Framework

Designed and programmed from scratch a distributed artificial intelligence framework capable of resolving incidents and planning infrastructure without human intervention. The system orchestrates a swarm of LLMs with specialized roles (Architect, SecOps, Developer) communicating asynchronously via message queues (mailboxes) and OS-level semaphores (locks) to prevent race conditions. Integrated with n8n automation flows, the system autonomously reads tickets, debates solutions in a broadcast channel, and modifies enterprise server environments safely, achieving an 80% reduction in Level 1 ticket resolution times.
