Project Description:

There is a ready project built on:

Frontend: Vue.js
Backend: Node.js (Express)
Database: PostgreSQL
Server: Ubuntu 24.04 with Nginx and PM2
Project Location: /www/scalevolt-app

The project works locally, but after updates and deployment on the server:

The website online returns 500 Internal Server Error
Frontend does not display or displays incorrectly
Backend/API does not work or returns errors (likely due to a database connection issue)
PostgreSQL does not accept connections (likely a password or configuration issue)

What Needs to Be Done:

Check and debug the project deployment on the server:
- To ensure the Vue frontend displays correctly
- To ensure the Node.js backend works and connects to PostgreSQL
- To ensure API routes respond without errors
Check the connection to PostgreSQL (password, access)
Ensure PM2 and Nginx are configured correctly
Set up a convenient update process (via Git or another solution)

Access:

I provide SSH access to the server
All files are already uploaded to the server: /www/scalevolt-app

What Should Be the Result:

The site should work correctly on the domain
Backend and database — connected
A brief guide on how to update the project and restart services

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
