AdShort AIAI-driven short-form ad platform — automated video generation, scheduling, and publishing.

The challenge

A France-based AdTech client needed to scale short-form video advertising across markets and languages, but their existing pipeline depended on humans for every prompt, render, and publish step. Output was inconsistent and campaign throughput was capped by team size.

What I built

I designed and built the end-to-end backend in NestJS + TypeScript, orchestrating Gemini and Vertex AI for prompt generation, media synthesis, and translation. The system handles scheduling, retries, and publishing across multiple ad networks with idempotent workflows so a failure mid-pipeline never corrupts a campaign.

• Modular NestJS backend with isolated prompt, media, and publish services
• Gemini + Vertex AI integration with structured outputs and retries
• Job scheduler with idempotent workflows and per-tenant rate limits
• Multilingual content automation across creation and posting

Outcome

Delivery speed improved by 60% and manual effort dropped 75%. Multilingual automation now runs unattended across creation and posting pipelines, and the marketing team ships more campaigns per week with more consistent output.
