C# Developer Needed to Upgrade, Deploy & Maintain My Microsoft Teams Automation Tool

I'm looking for a skilled C# developer to upgrade my existing Microsoft Teams automation app, convert it to WPF (.NET 8 LTS), and deploy it on a Windows VPS for 24/7 operation. The core functionality (login, join, post) is already working — you’ll mainly improve structure, stability, and automation reliability. Your responsibilities include development, VPS setup, session management, crash recovery, and daily logging/reporting. Full checklist is attached in the doc file. Only apply if you're confident in both C# WPF and VPS automation.
