MarketInLab Company Portal

MarketInLab Service Portal is a full-stack SaaS platform built to replace a fragmented, manual workflow with a centralized digital system. It supports three distinct user roles — admin, employee, and client — each with their own permissions, dashboards, and protected routes enforced through Supabase Auth and JWT-based authorization.

The platform unifies seven core modules into a single coherent system. Clients browse and subscribe to service plans, manage a cart with coupon support, complete payments through a Cashfree integration with webhook verification, and track their orders, invoices, and wallet credits. Employees handle attendance through a punch-in/out flow with selfie + location verification, with a cron-based auto punch-out for missed entries, plus a ticket system that walks issues through an Open → In Progress → Resolved → Closed lifecycle (with reopen support). Admins get full system control: creating users, managing services and plans, assigning tickets, and overseeing payments and wallet transactions across the entire organization.

The architecture follows a clean MVC pattern on the backend (Express.js + Node.js), with PostgreSQL on Supabase as the data layer and a normalized schema covering users, services, orders, payments, wallets, credit transactions, tickets, and attendance. The frontend is a responsive React application with Tailwind CSS, deployed on Vercel; the backend runs on Render; emails flow through Resend; uptime is monitored via cron-job.org. Security is layered — bcrypt password hashing, JWT validation on every protected route, server-side payment verification, and input validation against SQL injection and XSS.

The system currently supports ~1,000 users in production, handles daily transactions through the payment gateway, and operates as a live revenue-generating platform for the firm. It's the project where I learned how every architectural decision compounds — and where I shipped something real users depend on.
