I am currently designing Jenial, a software suite dedicated to audiovisual production assisted by generative artificial intelligence.

The objective of Jenial is to structure a complete workflow for moving from a creative intention to usable production elements: script analysis, breakdown, storyboard, image generation, video generation, visual continuity, reference management, shot preparation, and integration into a post-production logic.

My role covers product vision, art direction, functional design, AI R&D, and development management. I am working on how generative models can be integrated into a real production pipeline, rather than being used as simple isolated tools.

The Jenial suite aims in particular to help creators, directors, producers, and audiovisual teams prepare, visualize, and generate sequences with more coherence, speed, and artistic control. It is based on a hybrid logic: preserving human intention, directing choices, and production constraints, while leveraging AI to accelerate pre-visualization, visual exploration, and content creation.

I am involved in defining workflows, product architecture, testing image and video models, continuity between shots, character consistency, visual reference management, automating generation steps, and creating interfaces adapted to the real uses of the cinema, series, and advertising industries.

This experience allows me to develop concrete expertise at the intersection of audiovisual creation, art direction, AI automation, and the design of specialized SaaS products for the creative industries.

Acculturation mission on new workflows for the creative and cultural industries in the luxury and audiovisual market.

Conception and managementfor 6 months of anAI pipeline for the production of approximately 70% of the shotsfor the series Déclics, broadcast on Arte.

Continuous R&D, automated storyboard extraction, ComfyUI / ControlNet / Flux workflows, Midjourney, Kling, and Veo tests, LoRA experimentation from season 1, batch automation, and production scripts.

**Objective**: to accurately reproduce the series' artistic direction — silhouettes in Chinese shadows, realistic sets, historical coherence, and controlled lighting — while producing over 600 video sequences within a 6-month timeframe.
