🍽️ Check Karo Bawe — AI-Powered QR Menu Platform

A multi-tenant SaaS that turns a physical restaurant menu into a live, scannable QR menu — personal project.

🏢 Multi-tenant: a super admin onboards restaurant admins; each restaurant gets a unique slug and an auto-generated QR code
🤖 AI menu import: upload a photo of a physical menu → GPT-4o vision extracts every dish (name, ingredients, price, veg/non-veg, spice level, taste tags, nutrition estimates) into an editable review table before committing; re-scanning updates existing dishes by name instead of duplicating them
⭐ Guest-facing menu: live search + filters (category, veg/non-veg, spice level, taste tags), star ratings with optional photo reviews per dish
🔐 JWT-based auth, role-based access, duplicate-dish protection

🧑‍💻 Face Recognition Attendance System — Lend A Hand India

A full-stack, multi-role (student/instructor) attendance platform built around on-device facial recognition, built at LAHI.

📱 Mobile app (Expo / React Native): on-device face verification via TensorFlow.js, geofenced + time-boxed attendance marking, layered auth (JWT + OTP + 4-digit PIN), jailbreak/root detection for tamper resistance
🖥️ Admin dashboard (Next.js + Tailwind): institute-level and super-admin management — calendars, maps, analytics
⚙️ API (NestJS + Fastify + MongoDB): JWT/Passport auth, Swagger docs, file uploads, email notifications
✅ Passed a live security (VAPT) audit before production rollout
