Show HN: AI agents run my one-person company on Gemini's free tier – $0/month

I'm a solo de in Taiwan. I built 4 AI agents that handle content, sales leads, security scanning, and ops for my tech agency - all on Gemini 2.5 Flash free tier (1,500 req/day). I use ~105. Monthly LLM cost: $0. Architecture: 4 agents on OpenClaw (open source), running on WSL2 at home with 25 systemd timers.
