End-to-end platform orchestrating content pipelines from creation through narration, rendering, and delivery. Built across three major versions.
F5-TTS Voice Cloning
Custom voice synthesis on serverless GPU
Fine-tuned the F5-TTS model on custom voice recordings. Deployed on serverless GPU with custom Docker container and CUDA 12.1.
AI Video Generation
5B-parameter diffusion model
Built and deployed the Wan2.2-TI2V-5B diffusion model on serverless GPU for text-to-video and image-to-video generation at 720p.
