I am looking for an experienced Laravel developer or a professional development team to build a complete, secure, scalable, and production-ready online auction platform inspired by Planet Express Auctions. Reference Website: https://auctions.planetexpress.com/auctions The platform will initially target the Bangladesh market, with BDT (৳) as the primary currency. This will be a multi-vendor auction platform where anyone can register as an individual seller and list their products for auction. Users will not be required to own a company or provide business registration documents. I am looking for a fully custom-developed platform with complete auction functionality, buyer and seller dashboards, wallet management, warehouse management, payment processing, and comprehensive administrative controls. This is not a basic auction script installation project. I need a complete and professionally developed application. 1. Technology Requirements Preferred technology stack: - Backend: Laravel 12 or the latest stable Laravel version. - Frontend: Laravel Blade + Livewire or another suitable modern frontend framework. - Database: MySQL 8. - Real-time bidding: Laravel Reverb / WebSockets. - Cache: Redis. - Queue Management: Laravel Horizon. - Search: Meilisearch or an equivalent solution, if required. - File Storage: S3-compatible cloud storage. - Currency: BDT (৳). The architecture should be scalable and suitable for future expansion. Hosting infrastructure is flexible; I can use VPS or Cloud Hosting if necessary. Developers may recommend alternative technologies with a clear technical explanation. 2.
