The Challenge
"I required an internal management system to efficiently handle multiple projects across different clients, manage team members and their allocations, and track financial metrics."
Architectural Solution
Full-stack MERN architecture with NestJS backend, React frontend with TypeScript, MongoDB database, and real-time WebSocket communication via Socket.io.
Engineering Deep Dive
An inside look at the structural decisions, trade-offs, and scaling plans devised during implementation.
Context & Constraints
- Handles multiple simultaneous projects for various global clients.
- Requires strict financial isolation and budget management.
- Team collaboration across distributed, remote-first team members.
Architecture Trade-offs
Chose NestJS for its strong architectural patterns and scalability. Selected MongoDB for flexible schema handling across different project types. Implemented Socket.io for real-time updates.
Database Modeling
MongoDB document schema with Mongoose models including Projects, Clients, Users, Tasks, ProjectFileLinks, and supporting collections for Reports.
