Classified Ads platform

Team size: 3

Duration: 12 months / part time

Main stack: Laravel + NuxtJS + Flutter for android + WPF for windows

Scale (users / data / requests): Medium-scale production system with real users

What problem did it solve? Solved the problem of connecting users through a classified ads platform for listing, discovering, and managing advertisements

What did I actually do? (not the team)

  • Designed and implemented the full-stack web architecture
  • Built backend APIs and data models using Laravel
  • Developed the web frontend using Nuxt for listing, search, and user interactions
  • Implemented authentication, authorization, and validation flows
  • Integrated frontend and backend for end-to-end web functionality

Hard parts / challenges:

  • Designing dynamic, category-based data models and form generation for different listing types
  • Ensuring correct validation and data integrity across flexible, user-defined inputs
  • Maintaining consistency between frontend state and backend logic under real user interactions

Biggest technical decision I made: Established a clean, layered architecture across both backend and frontend to keep complex domain logic independent from UI and ensure long-term extensibility

Result / impact (even rough): Completed a production-ready system prepared for launch, with deployment postponed for business-related reasons

Internal complexity:

  • Time-based and asynchronous processing handled through background queue jobs (e.g., listing promotion)
  • Multiple listing categories with category-specific dynamic fields
  • Dynamic form generation and validation logic shared between frontend and backend
  • Complex data relationships between users, listings, categories, and metadata
  • Role-based access control and ownership rules for user-generated content
  • Time-based listing promotion handled via background queue jobs
  • Synchronization between frontend state and backend validation for dynamic inputs
  • Security-sensitive validation across all listing and user actions
  • Clean, layered architecture applied consistently across backend and frontend
