Small businesses need Meta/Instagram ads but can't afford agencies ($2,000-5,000 per campaign). PhotoAI generates 6 professional ad variants from 1 product photo in 60 seconds — no prompt needed, everything comes from smart forms. Our cost: ~$0.15 per generation. Agencies charge $200-500 per concept.

The admin panel was built before the app — 70+ pages, 12-layer security, promotion engine with approval workflows, seasonal themes per country, A/B testing, error monitoring, and financial dashboards. One person can operate the entire multi-market platform without engineering tickets.

Building a personal brand as a solo developer means no time for manual content creation. So I built a system that does it: scans 60 topics across 7 data sources weekly, scores opportunities with a multi-signal AI algorithm, and produces finished content — carousels, videos with AI voice and music, captions — ready to publish.

The system publishes across 10 social channels in English and Spanish — Instagram, LinkedIn, Facebook, Threads, YouTube. It includes a custom Remotion video renderer with a 7-stage audio mastering pipeline that brought levels from -58 LUFS (inaudible) to broadcast standard. Scripts require my approval; after that, everything is automated end-to-end.
