Golang Freelance Jobs

I need someone to deploy my fully developed project built in Node.js, React.js, Vite, TypeScript, and GoLang using a Postgres database.

Key Requirements:
- Deploy the project on a Linux server (Ubuntu preferred)
- Configure Nginx and PM2 for the server
- Connect my registered domain to the backend
- Provide instructions for future self-deployment

Ideal Skills:
- Extensive experience with Node.js, React.js, GoLang, and PostgreSQL
- Proficiency in setting up and configuring Nginx and PM2
- Familiarity with domain connection procedures
- Experience with teaching and providing clear instructions for non-technical individuals
