We look for a experienced developer to review the code for security issues, deploy it to our VPS, and provide ongoing maintenance and support. One-time tasks 1. Code review — Review the full codebase for security vulnerabilities, bad practices, and hardening opportunities 2. Infrastructure review — Verify Dockerfile, environment variable handling, and database setup are production-safe 3.
