Indian brands lose weeks every festive season to one problem nobody talks about. Localization. Same campaign. Multiple languages. Broken layouts. Butchered translations. Lakhs spent. Launch delayed.

I built an ad engine on Melius to kill that problem.

Meet UTSAVA. A single canvas that takes three main inputs: a brand, a product and a festival. What comes out the other end is a complete campaign. Lifestyle heroes, product catalogue, mood boards, a 30 second product film, luxury posters, and city placements across Mumbai, Delhi, Chennai, Bangalore and Kerala. All of it localized. Automatically.

190+ nodes. Parametric brand inputs at the top feeding a creative direction agent layer in the middle. Built to be swappable, not hardcoded to one brief.

To prove the architecture I ran it on a mock brand. ARASU. A fictional royal dry fruit gifting brand. Diwali brief. The engine did the rest.
