Cloud and AI-native SaaS
Niroobini Technologies is a cloud and AI-native SaaS company. We build specialized products — not a general toolkit — so each app is deep in one domain and runs in the browser.
Our core engineering product is NirTsCAD: a general-purpose CAD drawing tool with familiar commands and Lisp support in the AutoCAD tradition. NirTsCAD has a special focus on structural engineering — CADMAX Buildings for RCC design and detailing, and Irrigation toolboxes for dam design and detailing. AI is built in: prompt from the CAD tab, or connect Cursor and Claude over MCP.
Next are other SaaS products, including NirTs-School, a school management app for student records, attendance, grades, fees, and transport.
