   Founder

   botline.id

   A platform for building WhatsApp chatbots. A business scans a QR code to connect its WhatsApp number, picks a template or draws the conversation in a flow builder, and the chatbot starts replying within minutes. For questions a script can’t handle, it uploads its documents and the AI answers from those.

   Broadcasts, several numbers in one dashboard, and a REST API with webhooks are part of the same platform. I build the Go services behind it and the retrieval layer that keeps the assistants to their sources.

   A sales assistant on Botline for the medical supplier I first built apps for in 2016. It answers from the product catalogue, scores each lead from 0 to 100 and gives its reason, then follows up by itself: one message every five days at most, stopping after three go unanswered. It passed 107 of 108 test scenarios before launch.
