Hello!

My name is Ruslan, I am a fullstack developer with experience in Node.js (Express), PostgreSQL, Nginx, PM2, as well as deploying projects on Ubuntu servers.

⚙️ I have full cycle deployment practice:

configured Nginx + SSL,

worked with process management systems (PM2),
…
connected the backend to PostgreSQL (including configuring pg_hba.conf, .env, migrations),

optimized the deployment flow through Git or CI/CD,

and dealt with 500 Internal Server Error type issues after updates.

🔍 In your case, I can quickly:

check pm2 logs and nginx/error.log,

test the connection to PostgreSQL,

identify the cause of incorrect frontend operation (Vue),

and set up the update process (Git pull + build + restart script).

I am ready to connect via SSH, conduct an audit, and fix everything. I will also provide a short instruction for future updates.

Write if relevant — I am ready to quickly get to work.

Best regards,
Ruslan
