Project description
ClientNest is a self-service customer portal that enables account, subscription, billing, and support management with real-time updates. It reduces support overhead by enabling customers to self-serve and access account information instantly.
Challenges we tackled and how we handled them
Subscription State Complexity - Modeled the subscription lifecycle as a state machine, ensuring transitions trigger billing, access changes, and notifications reliably.
Real-time Support Ticketing - Built a WebSocket-based notification system for instant ticket updates and implemented email fallbacks for offline notifications.
Secure Payment Handling - Integrated Stripe for tokenized payments, storing only secure tokens and handling payment events through verified webhooks.
Multi-tenant Data Isolation - Enforced row-level security in PostgreSQL and validated tenant context in API middleware to guarantee strict data isolation.

Problem Solving
Challenges We Tackled
Every project presents unique challenges. Here's how we approached and solved the key technical hurdles.
Subscription State Complexity
Managing various subscription states (trial, active, paused, cancelled, expired) with grace periods and proration.
Implemented a state machine pattern for subscription lifecycle management. Each state transition triggers appropriate events for billing, access control, and notifications.
Real-time Support Ticketing
Customers expect instant updates on their support requests without refreshing the page.
Built a WebSocket-based notification system that pushes ticket updates, agent responses, and status changes in real time. Integrated with email for offline notifications.
Secure Payment Handling
Storing and processing payment information requires PCI compliance and secure token management.
Integrated with Stripe for payment processing, storing only tokenized references. Implemented secure webhook handling for payment confirmations and failures.
Multi-tenant Data Isolation
Each customer's data must be completely isolated while sharing the same infrastructure.
Row-level security policies in PostgreSQL ensure data isolation. API middleware validates tenant context on every request.
