Senior Unity Developer for Game Enhancement

@KESHAVINFOTECH

Hi, This is primarily a live-production handover, not a new build. The main risk is disrupting login, sync, or deployment while transferring ownership from the existing GitHub/Docker setup into your stack. I’ve taken over live Unity games before, and for this migration I’d treat it as a controlled transfer: recover the current configuration, document dependencies, and move one piece at a time. My first priority would be a safe backend takeover with rollback protection: rebuild the repo, re-establish Firebase/DigitalOcean/Docker infrastructure, review API keys, and verify login and live-build stability. After that, I’d address multiplayer health, sync/matchmaking issues, and performance cleanup to keep the game stable as you add new modes and admin tools. Relevant experience: - Audit Unity/backend workflows - Rebuild deployment ownership - Restore Firebase, DigitalOcean, and Docker setups - Verify authentication and live-service stability - Identify multiplayer and scaling risks One quick question: do you have access to the backend source and deployment scripts, or only the Unity project and live service accounts?

@siphomdletye

Hey — saw your post about needing a Senior Unity Developer for backend takeover and multiplayer improvements. A common pain point here is syncing multiplayer code with backend changes without causing downtime. Quick question: Is your current backend built on a specific framework that we need to integrate with Unity, or is there flexibility to refactor parts? I’ve handled multiple Unity projects with backend migrations and real-time multiplayer tweaks that improved stability and performance. Send over any specs or current architecture info, and I’ll take a look and share a plan.
