Project Portfolio

Welcome to my technical portfolio. Here you will find case studies and projects where I have designed, implemented, and maintained solutions in IT infrastructure, automation, cybersecurity, and web architecture.

Infrastructure & Automation (SysAdmin / DevOps)

ClickDeploy – Automated SaaS Deployment Platform

  • Domain: Systems Administration, Virtualization & Automation

  • Stack: Docker, Bash Scripting, Nginx, MariaDB, TrueNAS, Netdata, Webhooks, PHP, Certbot (SSL)

  • Repository / Demo: View on GitHub

  • The Challenge: Eliminate manual intervention in provisioning web environments (WordPress, Moodle, Nextcloud) while ensuring tenant isolation, performance, and security.

  • The Solution: Design and deployment of a distributed SaaS platform. Integrates a main compute node running Docker containers with a dedicated TrueNAS storage server. Automation is handled via Bash scripts and webhooks for instantaneous deployments, domain assignment, SSL certificate generation, and database audit logging.

  • Impact & Results:

    • Complete, zero-touch automated deployments in seconds.
    • Full audit trail and historical logging at the database level.
    • Real-time server resource and health monitoring via Netdata.
