EasySearchRajshahi Local Services Marketplace Platform

Rajshahi, Bangladesh's fourth-largest city, lacked a centralized platform for discovering and accessing local services. Residents struggled with fragmented service discovery across rentals, healthcare, catering, and tourism; information asymmetry with no way to compare prices or verify quality; language barriers excluding Bengali speakers; trust and safety concerns without provider verification; and the technical complexity of building a monolithic platform with 16+ distinct service modules while maintaining code quality and performance. Additionally, 70% of target users access services via mobile devices, requiring a responsive mobile-first approach.

Scope: 16 backend modules, 89 API endpoints, 14 frontend API slices, 12+ public pages, admin dashboard, authentication system, Cloudinary image pipeline, Swagger documentation, Leaflet map integration, bilingual support, SEO optimization

Adopted a modular monolithic architecture with clear separation of concerns. On the backend, designed 16 independent NestJS modules with MikroORM for type-safe PostgreSQL operations, 89 RESTful API endpoints with Swagger documentation, JWT authentication with Passport.js, Cloudinary integration for image storage, and approval workflows for content moderation. On the frontend, leveraged Next.js 16 App Router with Redux Toolkit and RTK Query for state management across 14 API slices, Leaflet for interactive mapping, React Hook Form + Zod for validation, and Framer Motion for animations. Used a phased implementation approach: Phase 1 for homepage integration, Phase 2 for missing endpoints, and Phase 3 for user management — all with TypeScript-first development for end-to-end type safety.

1. Problem

   Complete absence of marketplace module (7 endpoints missing)

   Solution

   Created comprehensive marketplace module with TypeScript types, RTK Query integration, full CRUD operations, and admin approval workflow in Phase 2

2. Problem

   Static mock data on homepage degrading user experience

   Solution

   Systematically replaced 4 homepage components with real-time API integration, implementing loading states, error handling, and empty states in Phase 1

3. Problem

   Complex state management across 16 service modules

   Solution

   Implemented Redux Toolkit with RTK Query for automatic caching, optimistic updates, and granular cache invalidation using tag-based system

4. Problem

   Type safety across frontend and backend integration

   Solution

   Created comprehensive TypeScript type definitions for all entities, DTOs, and API responses ensuring end-to-end type safety with zero errors

5. Problem

   Image upload and storage at scale

   Solution

   Integrated Cloudinary for cloud-based image storage with automatic optimization and CDN delivery using Multer for multipart form handling

6. Problem

   Authentication and authorization for multi-role platform

   Solution

   Implemented JWT-based authentication with Passport.js strategies, role-based guards, and refresh token mechanism
