My client needed a comprehensive investment management platform to launch their fintech startup. They required a secure, scalable solution with user-friendly interfaces for investors and robust administrative controls.\
I delivered a complete three-tier ecosystem: a React-based investment portal for end users, an admin dashboard for platform management, and a secure Node.js backend API. The user portal features real-time investment tracking with ApexCharts visualization, secure KYC verification using facial recognition, and an integrated referral system. The admin panel provides complete oversight with automated profit distribution, payment verification workflows, and analytics dashboards.\
The backend implements enterprise-grade security with Firebase authentication, Bcrypt encryption, and MongoDB for scalable data management. I integrated Twilio for SMS notifications and built comprehensive middleware for validation and error handling.\
Key challenges included implementing secure facial recognition for KYC compliance and designing an automated profit distribution system. I solved these by integrating Face API.js with custom validation logic and creating scheduled jobs for profit calculations.\
Tech Stack: React 18, Vite, Tailwind CSS, Node.js, Express, MongoDB, Firebase, Twilio.\
Deliverables included fully functional user and admin portals, documented REST API, database schemas,
