   botline.id

   Botline makes WhatsApp chatbots fast to build, affordable to run and light to operate, with a working chatbot live in minutes. For anything beyond a scripted flow, LLM assistants use retrieval (RAG) and vector search to answer from a company’s own documents.

   Visual flows, broadcasts and a REST API with webhooks sit on the same platform. I work across every layer: the Go and Python services, the retrieval layer that keeps each assistant grounded in its sources, and the self-hosted Kubernetes platform underneath.

   Mulya Husada Jaya Care

   Demo video, in Indonesian

   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.
