GLOREP CMS - ID (Compliance & Identity Verification Platform)
February 1, 2023 – February 1, 2026
Backend system for identity verification and compliance workflows, handling KYC processing, risk evaluation, and large-scale document management for individuals and entities. Designed a multi-tenant backend system supporting high-volume data processing, concurrent workflows, and performance-critical operations with strict tenant-level isolation. Built secure, scalable REST APIs for identity verification and risk-based compliance workflows, supporting dynamic onboarding and event-driven processing. Architected a dynamic verification workflow engine with configurable, step-based KYC processes, supporting multiple flow types with admin-driven rules, and a highly configurable risk matrix applied across both user verification and internal admin workflows, along with resumable sessions and expiry controls. Implemented multi-level role-based access control (RBAC) with granular permissions and secure authentication using JWT, CSRF protection, TOTP-based 2FA, and field-level encryption via Mongoose hooks. Optimized bulk CSV import pipelines, processing 50K+ encrypted records in under 15 minutes using streaming and batch processing techniques. Designed a MongoDB audit logging system handling 100K+ activity records, ensuring traceability, compliance, and high-performance querying. Built a scalable notification and email queue system processing 5K+ records daily with controlled concurrency (p-limit), retries, and delivery tracking. Implemented large file handling using MongoDB GridFS and developed streaming APIs for serving large media (base64) with memory-efficient processing. Developed cluster-aware schedulers using node-cron and IPC, enabling distributed job execution across multiple Node.js clusters. Built a configurable event-driven system allowing admins to define custom events and webhook integrations with detailed request/response logging, retry mechanisms, and failure tracking, along with a developer portal for API key management and external system integration. Implemented a credit-based usage system tied to verification operations (manual, workflow, and scheduled), with audit tracking. Designed and implemented a Stripe-based billing system with dynamic subscription plans and credit-based pricing, enabling super admin-controlled monetization and flexible usage models for tenant admins.
