Senior AI Video & Systems Specialist – Server Setup & Automated Production Pipeline (ComfyUI, n8n, RTX 5090)

I am seeking an expert AI Systems Specialist / Technical Director to configure and optimize a high-performance local AI production server. The goal is to build an end-to-end automated pipeline for producing hyper-realistic AI mini-series featuring consistent realistic characters, lip-synced dialogues, cinematic editing, and automated multi-platform publishing (Instagram, TikTok, Facebook, along with NSFW variants for premium platforms).

Server Hardware & Environment
OS: Ubuntu 26.04 LTS
CPU: Intel Core Ultra 9 285K (24 Cores / 24 Threads)

Server Setup & Stack Configuration:

Complete Ubuntu environment setup optimized for PyTorch, CUDA, and high-vram local inference.
Deployment and tuning of ComfyUI, Open WebUI, and n8n.
AI Character & Video Production Pipeline:
Build advanced ComfyUI workflows leveraging SOTA open-source video/image models.
Implement character consistency tools using LoRAs and IP-Adapter/ControlNet pipelines.
Integrate lip-sync and dialogue tools (e.g., LivePortrait, MuseTalk, ElevenLabs, or equivalent).
Apply cinematic director tools (camera movement control, upscaling, frame interpolation).
Automation & Multi-Platform Distribution:
Create n8n automated workflows connecting rendering, video assembly, audio mixing, and export.
Auto-posting pipeline for social media channels (Facebook, Instagram Reels, TikTok).
Separate workflow path for rendering and managing NSFW versions for paid platforms.

Required Skills & Technical Stack
Deep expertise in ComfyUI, custom nodes, and advanced workflow architecture.
Mastery of open-source AI image/video models, character LoRAs, and motion control.
Strong background in n8n, Linux server administration (Ubuntu), and Python environments.
Hands-on experience with AI lip-sync, voice synthesis, and cinematic framing techniques.
Familiarity with social media API integrations and automated posting tools.

Inputs Provided
Fully dedicated local server (RTX 5090, 32 GB VRAM).
Scripts, storylines, and character reference images.
Subscriptions/API access where required.

Note: Amateurs/beginners please refrain from applying. Proven portfolio of AI video workflows, character consistency, or automated production pipelines is required with your proposal.
