This one was all about automating ad creation. Marketers spend way too much time writing copy and setting up campaigns, so I built AdSync Pro with Django and Next.js. The backend handles LLM prompt pipelines that generate ad text automatically, and the frontend gives you a clean dashboard to manage everything. I also added real time analytics because who doesn’t want to see their campaign performance instantly? It ended up managing over 100 campaigns and automated about 90% of the manual work. Pretty satisfying.
