Muzaffarpur, Bihar's fast-rising East India hub, is the litchi capital and power-loom trade city of north Bihar. Its economy runs on litchi cultivation, processing and export, power-loom textiles and small manufacturing and education and a divisional-headquarters economy — and its litchi-export and textile units are digitising. Each of those is being reshaped by AI, which is why a Prompt Engineering skill lands in Muzaffarpur rather than in the abstract.
So ONROL's prompt engineering is prompts built as tested, versioned, production artifacts, taught against Muzaffarpur's actual work: you build, test and harden prompts that survive production for litchi cultivation, processing and export and power-loom textiles and small manufacturing the way teams here do. You get speed from AI and the judgement to use it — Prompt Engineering, not a generic overview.
The finish line is a published prompt-engineering project you keep as portfolio on a real Muzaffarpur scenario — evidence an employer in Mithanpura or Kalambag Road can judge in one read, not a paper certificate. Learners come from Mithanpura, Kalambag Road, Aghoria Bazar and Brahmpura.
