Mens Mercatus is Katlego Mokoto's AI agents and LLM automation practice, working with SMEs up to enterprise teams, for clients globally. The rule behind every build: the system does the slow work, and a person makes the call before anything irreversible happens. Flagship systems: JobNet: a daily career pipeline that turns public job posts into a ranked shortlist and tailored application drafts. Every email waits in Gmail as a draft, and Katlego reviews it and presses Send himself. Mercatus Assist & THINK: a C# / ASP.NET Core 8 service and a React 19 workspace that call Gemini from the server, so the API key never reaches the browser. Backoff on 429 and 5xx errors, per-IP caps, live voice, replies in isiZulu, Afrikaans or Sesotho, and a labelled demo mode when the live path is down. How it is built: model calls behind a .NET/C# service, approved tools only, retries, rate limits and health checks from the first public version, and a human gate before any send, payment or other irreversible step. Pilot testers wanted: I'm looking for 3 businesses to pilot a free AI agent on one real task, such as inbox triage, FAQ replies or invoice capture. Agents draft, your team approves.
