Problem & Product Vision

AdNexo is a comprehensive multi-tenant ads management platform built to streamline ad booking, print distribution, agency campaigns, and site owner inventory. Dedicated interfaces and permission models were engineered for 5 user personas.

System Architecture & Tech Stack Design

React/Redux SPA frontend communicating with a high-throughput Node.js microservices backend. API specifications are documented and validated via OpenAPI/Swagger. Real-time notifications and payment verification run via Socket.io and Razorpay webhooks.

Engineering Responsibilities & Accomplishments

Architected role-based management panels for Individual, Company, Agency, Site Owner, and Printer users
Designed and documented comprehensive RESTful APIs using Swagger OpenAPI specifications
Integrated Razorpay payment processing and Socket.io real-time campaign status notifications
Executed automated API endpoint testing and CI/CD deployment pipelines

Technical Challenges & Engineering Solutions

Role-based access control across 5 distinct user types

Designing authorization logic for 5 user tiers (Agency vs Printer vs Site Owner) required a clean JWT RBAC middleware layer to prevent cross-tenant data access.

Key Retrospective & Takeaways

Architectural Lessons Learned

Writing clear Swagger OpenAPI specifications before building frontend views cuts integration bugs between web and mobile teams by over 40%.
