HisaabAI
AI construction budget tracker - closed beta, co-founder
An AI-powered construction budget tracker for homeowners and small contractors building or renovating in India. Contractor PDF estimates get parsed into stage-wise budgets automatically, and site expenses get logged by voice or bill photo instead of WhatsApp threads and paper notes - with an in-app assistant, Ask HisaabAI, answering plain-language budget questions grounded only in that project's real data via function-calling (no hallucinated numbers). Co-founder and full-stack/AI engineer, with a co-founder handling construction-domain expertise, GTM, and contractor relationships. Multi-tenant with role-based access (owner/admin/worker/client). Stack: Expo (React Native), Expo Router, Express 5, Drizzle ORM, Zod, Supabase (Postgres), Cloudflare R2, Railway. Currently closed beta, invite-only.
