We have an AI Chatbot backend (FastAPI + Uvicorn) currently running under root on a Hostinger Ubuntu 24.04 VPS. The frontend is on GitHub. We already have a Python developer — what we need is an experienced Linux/VPS engineer to migrate and set up a secure, production-ready deployment. Scope of Work: Move backend from root → dedicated Linux service account with virtual environment. Set up systemd service for process management and auto-restart. Prepare for multiple chatbots (2–3 planned), each with its own service account + venv. Migrate frontend (currently GitHub) → VPS and configure under Nginx. Ensure Nginx reverse proxy + Let’s Encrypt SSL continue working for saavigen.ai and api.saavigen.ai. Provide a simple runbook for managing services and SSL renewals. Requirements: Strong Linux system administration experience. Familiarity with Python venv deployments (FastAPI/Uvicorn). Hands-on experience with Nginx reverse proxy and SSL certificates.
