Vici Server Manager - VoIP Automation Platform

<div class="space-y-6">
<div class="prose prose-invert max-w-none">
<h2>🎯 Project Overview</h2>
<p>
Built a <strong>centralized automation platform</strong> to manage multiple VoIP servers from a single web interface.
The system eliminates manual SSH commands and error-prone text file editing by providing one-click deployment,
configuration generation from templates, and live terminal output streaming.
</p>

<h3>💼 Business Impact</h3>
<ul>
<li><strong>95% time savings:</strong> Deployment time reduced from 30 minutes to under 2 minutes per server</li>
<li><strong>Error reduction:</strong> Configuration mistakes dropped from ~15% to &lt;1%</li>
<li><strong>Audit compliance:</strong> Complete change history with who/what/when for every deployment</li>
<li><strong>Team scalability:</strong> Non-technical staff can now deploy configurations safely</li>
<li><strong>Disaster recovery:</strong> One-click rollback to previous configurations</li>
</ul>

<h2>🔧 Technical Challenges Solved</h2>

<div class="border-l-4 border-yellow-500 pl-4 my-4">
<h4 class="font-bold">SSH Connection Pooling</h4>
<p><strong>Challenge:</strong> Opening/closing SSH connections for every command was slow (3-5 seconds per operation).</p>
<p><strong>Solution:</strong> Implemented connection pooling with Laravel cache. Connections stay alive for 5 minutes, reducing overhead from seconds to milliseconds.</p>
</div>

<div class="border-l-4 border-yellow-500 pl-4 my-4">
<h4 class="font-bold">Concurrent Deployment Race Conditions</h4>
<p><strong>Challenge:</strong> Multiple users deploying to same server simultaneously caused conflicts and file corruption.</p>
<p><strong>Solution:</strong> Added mutex locks per server using Redis. Deployments queue automatically when server is busy.</p>
</div>

<div class="border-l-4 border-yellow-500 pl-4 my-4">
<h4 class="font-bold">Configuration Validation</h4>
<p><strong>Challenge:</strong> Invalid configs would break Asterisk after deployment, causing downtime.</p>
<p><strong>Solution:</strong> Pre-deployment validation using <code>asterisk -rx "pjsip show endpoint test"</code>, automatic backups before every change, and rollback on error detection.</p>
</div>

<div class="border-l-4 border-yellow-500 pl-4 my-4">
<h4 class="font-bold">Real-Time Output Streaming</h4>
<p><strong>Challenge:</strong> Users couldn't see what was happening during deployments—felt like a black box.</p>
<p><strong>Solution:</strong> Implemented Server-Sent Events (SSE) to stream command output line-by-line. Users see exactly what's executing in real-time.</p>
</div>
