Dominic Frei

I build pendpost at Nomadik GmbH in Switzerland. pendpost is a local-first, MIT-licensed social media planner where an AI agent drafts and schedules posts and a human approves them before anything goes out. I run it every day for my own projects, so the blog is written from that work: the platform API limits we hit, the errors we fixed, and the guardrails that keep an agent from getting an account banned.
