AI Product Engineer and Business AI Head
ModeliaThe AI solution for the fashion ecosystem
A complete AI solution for the fashion ecosystem: DAM and PIM, catalogue management, product imagery and visual master generators, with bulk generation across an entire catalogue.

01
The problem
Fashion brands need product imagery for every item in a catalogue, kept in order alongside the product data itself. On the merchant side, Modelia's Shopify app had grown into two isolated platforms with separate payments and generation history, and that split showed up as client escalations.
02
What I built
Modelia generates thousands of AI images and videos every day for fashion and e-commerce merchants. As AI Product Engineer and Business AI Head, I work across the generation engine, the Shopify app merchants use, the Studio creative tool and the internal systems behind them. I built the AI video production tool, unified and restructured the Modelia app for Shopify merchants, which cut client escalations by more than 95%, and rebuilt the legacy codebase into a modular system in 35 days.
