Ubuntu HA Cluster Mentorship & Development

Job ID: 40355366

Budget: €12 – €18 EUR

Technical Mentor & Operative Architect: HA Ubuntu Cluster (Mailcow, Apache, MariaDB Replication)

Job Description:
[IMPORTANT: READ CAREFULLY BEFORE APPLYING]
I am NOT looking for someone to just build a server and hand over the keys. I am looking for a Technical Mentor / Instructor and Operative Architect who will build a high-availability (HA) SaaS infrastructure on Ubuntu Server together with me.

The goal is full knowledge transfer. You will act as my "Co-Pilot," teaching me every step so that I can maintain, troubleshoot, and scale the system myself. You should also be open to a long-term relationship for future Q&A and support.

The Tech Stack & Requirements:

OS: Ubuntu Server (Hardened).

Orchestration: Docker & Kubernetes (K3s/MicroK8s preferred).

Mail: Mailcow (Docker-based) integrated into the architecture.

Web: Apache for PHP applications.

Database: MariaDB Cluster & Replication (Galera or Master-Slave with automated failover).

Security: 3-Way Backup Strategy (Local, Hot-Standby, Off-site) that is 100% restorable by me.

MANDATORY APPLICATION REQUIREMENTS:
To filter out generic applications and AI-generated spam, you MUST include the following in your proposal:

Step-by-Step Training Plan: How will you teach me the stack? (From Ubuntu basics to the MariaDB Cluster).

Project Implementation Plan: A timeline of how we will set up the production environment.

No AI-Generated Responses: If your proposal looks like a standard ChatGPT template, it will be immediately rejected. I am looking for a human expert with a personal teaching touch.

The Goal:

Zero Downtime: If one server fails or is overloaded, everything must keep running.

Sovereignty: I need to be able to rebuild the 3-way backup system myself if necessary.
