01
An AI model for each task
The service uses models from OpenAI, Anthropic and Google Gemini. It automatically chooses a model for each task, so users do not need to know the differences between them.

Ghstops from idea to launch in four months
I built Ghstops to bring content planning, production and publishing across channels into one place. I designed the architecture and built the service from idea to launch in four months using AI-assisted development.
I brought AI, publishing channels, subscriptions, languages and background tasks into one service. I was responsible for both the software design and keeping it running.

02
Publishing to social channels
The service creates text and image carousels in the background. Users review, schedule and publish to Facebook, Instagram, LinkedIn and X from the same view.
03
Automated billing
Stripe handles subscriptions, free trials and EU VAT. Routine billing runs without manual work from users or administrators.
What this work demonstrates
Users can create content, review it and publish to different channels. I used AI to help with coding and took responsibility for the design, system connections and launch.
