I need an experienced Laravel back-end specialist to build “Unikeys”, a central bank for digital software keys. The application will live on PHP/Laravel and expose a secure RESTful API that keeps several Joomla + HikaShop B2C stores in sync and, later on, will power a B2B reseller portal. > Core Scope: - Centralized Inventory: Track every license from intake to final sale, including status changes (New, Sold, Blocked) and audit history. - High-Integrity API: Provide a robust endpoint suite for my external shops to reserve and retrieve keys. Crucial: Must implement Database Transactions & Row Locking to prevent "Race Conditions" (selling the same key twice simultaneously). - Smart Allocation Logic (Business Critical): The API must receive the customer's email and apply the following logic: 1. Anti-Duplication: Check global history to ensure the same serial string is never assigned to the same email twice. 2. Multi-Slot Optimization: Prioritize filling remaining slots on multi-user licenses (e.g., 3-user pack) before dispensing a fresh key. - Legacy Data Migration: Create a seeder script to import 50,000+ historical sales (Email + Serial CSV) to populate the allocation history and prevent duplicate assignments to returning customers. - Admin Dashboard: Build a management panel (using FilamentPHP or Laravel Nova is preferred for speed) for stock uploads, sales analytics, and API Token management. - Joomla Integration: Develop the custom HikaSerial Generator Plugin (or provide the precise PHP cURL integration code) to connect my HikaShop stores to this API. > Key Expectations: - Clean, PSR-compliant Laravel 10/11 code (PHP 8.2+). - Security First: Token-based auth (Sanctum), rate limiting, and encrypted storage for sensitive keys. - Well-documented API: OpenAPI/Swagger auto-generated documentation. - Deployment: Docker setup for easy staging/production deployment. > Acceptance Criteria: 1. External store can retrieve a unique key via API within 300ms average latency. 2. Concurrency Test: 10 simultaneous requests for the same product result in 10 unique keys sold (no double spend). 3. Smart Allocation Test: A returning customer (identified by email) never receives a key they already own, even if stock is mixed. 4. Dashboard correctly reflects stock movements in real-time. If you have shipped comparable high-traffic Laravel APIs and understand the importance of atomic operations in inventory management, I’d like to see your approach and timelines.

I will build Unikeys on Laravel 10+ (PHP 8.2) with Sanctum auth, PSR-compliant services, DB transactions + row-level locking for atomic allocations, and OpenAPI-generated docs — Filament for the admin UI and Docker for staging/production. My approach: design the schema and allocation algorithm first, implement the high-integrity API with smart-allocation/multi-slot logic and legacy seeder, then add the admin panel, HikaShop integration snippet, automated tests (including concurrency stress tests), and CI-backed deployment; Redis queues and efficient indexing will ensure the 300ms target. Estimated timeline: 4–5 weeks (Week 1: design + schema + seeder; Weeks 2–3: API, allocation logic, concurrency tests; Week 4: admin UI, Joomla/HikaShop integration, docs; Week 5: QA, performance tuning, Docker deployment). I’ll provide test plans demonstrating the concurrency and smart-allocation acceptance criteria and a concise hand-off with runbook and monitoring suggestions.

Hello, I’m Muhammad Awais, a Laravel back-end specialist ready to build Unikeys, a centralized license inventory with a secure REST API to sync Joomla/HikaShop stores and power a B2B portal. I’ll deliver a PSR-compliant Laravel 10/11 backend (PHP 8.2+), token-based auth via Sanctum, rate limiting, and encrypted storage for sensitive keys. The system will track every license from intake to sale with an audit history and expose a robust API using database transactions and row locking to prevent race conditions. Smart allocation will enforce anti-duplication by email, and prefer filling remaining slots on multi-user licenses before issuing a fresh key. A seeder will import 50,000+ historical sales to seed allocation history and prevent duplicates for returning customers. Admin will be built with Filament or Laravel Nova for stock, analytics, and API token management. Joomla integration will be via a HikaSerial Generator or precise PHP cURL code to connect HikaShop to the API. OpenAPI docs will auto-generate, and Dockerized deployment will cover staging and production. I’ll test latency targets around 300ms for key retrieval, concurrency of 10 simultaneous requests, and real-time stock movement in the dashboard. I’ll share a detailed plan, milestones, and risk log on confirmation. What hosting environment and CI/CD do you prefer for Dockerized deployment? What is the max keys per product and desired DB isolation level under peak load? Do you need multi-region deployment and act

With a decade-long experience in PHP (Laravel, CI, CakePHP, Yii) and backend development, I have successfully delivered a plethora of projects, including similar central data management systems. I understand the challenge of inventory management and the significance of highly secure RESTful API with sound transaction and row locking methodologies. Not only can I ensure a robust endpoint suite for your external shops to seamlessly reserve and retrieve keys but also guarantee the prevention of any "Race Conditions" that might lead to selling the same key twice simultaneously. Moreover, adopting an anti-duplication framework is paramount for a project of this magnitude. Applying smart allocation logic like a multi-slot optimization will be my priority while creating the powerful Laravel-based B2B reseller portal you seek. Finally, using FilamentPHP or Laravel Nova in building your admin dashboard is preferable for me too. And yes, token-based auth, rate limiting, and encrypted storage for sensitive keys are pivots of my security measures along with well-structured API documentation. I am eager to discuss in depth on your expectations and how my skill set can be utilized to meet them effectively. Let's lock and load this project! Thanks....

What's your plan for handling the legacy data migration smoothly? Using something like Laravel's seeder scripts could streamline the import of those 50,000 sales records and maintain that anti-duplication strategy. Also, for that high-integrity API, what’s your approach for implementing row locking to avoid those race conditions? Let's make sure this thing runs smoothly!
