Mind AI

A two-chatbot, multi-agent RAG assistant for factory licensing and law advisory, built into the Ministry's e-License system and passed final acceptance for production. It replaced pick-a-law chatbots with a fan-out that queries every relevant law in parallel and summarises one grounded answer. Applicants can also check uploaded Thai PDFs, images and Word files for missing items through parallel VLM OCR.

About

Engineer first, then the model

Portrait of Wijak Manoprang in a dark blazer

I'm an AI engineer in Bangkok with a robotics background. I like systems that are measured before they're trusted.

I studied Robotics and Automation Engineering at KMUTT, focusing on AI and intelligent systems. Before LLMs I built with Arduino, ESP32, Jetson Nano and Raspberry Pi, which is why I care about where models run as much as what they say. Today I design multi-agent workflows, evaluate them with domain experts and deploy them on infrastructure the client controls.
