Expanded an existing multi-portal platform with a public-facing reporting layer, enabling external stakeholders to securely query, filter, and export complex datasets without compromising system integrity.

The Challenge:
External partners needed read-only access to aggregated data for analysis, but the existing system lacked secure public interfaces or export capabilities.

My Solution:
• Designed a secure, read-only API layer with strict RBAC to isolate public queries from core application data
• Built a high-performance search interface with real-time filtering, pagination, and on-demand export to PDF/CSV/Excel
• Developed specialized transaction forms to streamline digital record-keeping workflows for internal users
• Implemented caching strategies and query optimization to maintain performance as dataset size grew
• Used clean integration patterns to deploy updates with zero downtime to existing modules

Results:

• Enabled client to share insights with partners without manual data extraction
• Improved data accuracy by reducing human error in reporting workflows
• System remained 100% stable during deployment with no user disruption

Tech Stack: Node.js, Express, MongoDB, PostgreSQL, Prisma ORM, React, Firebase Functions, RBAC

Led end-to-end development of a complex multi-portal web platform designed to manage critical physical assets and sensitive datasets across four distinct user roles: administrators, field agents, end-users, and regulators.

🔹 The Challenge:
The client needed a unified system to replace fragmented spreadsheets, Microsoft Access DB and manual processes, with strict security requirements and real-time collaboration capabilities.

🔹 My Solution:
• Architected a modular React + TypeScript frontend with dynamic form handling (React Hook Form + Zod) to manage complex data entry workflows
• Built a scalable Node.js/Express.js backend deployed via Firebase Functions, enabling serverless auto-scaling during peak usage
• Designed a flexible MongoDB schema to support evolving asset lineage tracking, transaction histories, and audit logs
• Implemented granular Role-Based Access Control (RBAC) to ensure data isolation and compliance across user types
• Integrated Firebase Firestore for live notifications and Cloud Storage for secure document management

🔹 Results:
✅ System launched on schedule and is currently managing live operational data
✅ Reduced client’s data reconciliation time by ~70% through automated workflows
✅ Received positive feedback on code quality, documentation, and communication

🔹 Tech Stack: React, TypeScript, Tailwind CSS, Node.js, Express, MongoDB, Firebase (Functions, Firestore, Storage), RBAC design patterns
