Service Marketplace Platform
A platform where users can provide and receive services. Supports subscription-based access, one-time payments, and real-time communication.
System Architecture & Design Patterns
Subscription Lifecycle Engine with Webhook Dispatcher & RBAC Authorization
Ensures seamless transition between free, tier-based, and enterprise service provider privileges with automated subscription sync.
- Role-Based Access Control (RBAC) middleware for multi-tenant service providers
- Stripe Subscription lifecycle synchronization via asynchronous webhooks
- Direct client-to-cloud presigned URL asset uploads for service portfolios
Engineering Challenges & Solutions
Subscription status sync failures leading to unauthorized access or premature feature locks.
Constructed a resilient event-driven Stripe webhook listener that updates tenant permissions atomically and logs unhandled webhook events for automated retry.
Server bandwidth exhaustion caused by high-resolution work portfolio uploads.
Offloaded media uploads by generating presigned AWS S3 / Cloudflare R2 URLs on backend, allowing clients to stream files directly to object storage.
