We are looking for an experienced Laravel developer to build a new module for our existing platform called Carmetric, a Laravel-based application for car dealerships. The goal of this project is to integrate the platform with MercadoLibre Uruguay so dealerships can synchronize their vehicle listings directly with their MercadoLibre accounts through the MercadoLibre API. This is NOT a standalone project — the developer must work on an existing Laravel codebase and extend the current dealership workflow. Main Objectives The module should allow car dealerships to: Connect their MercadoLibre Uruguay account to Carmetric Publish vehicles simultaneously on Carmetric and MercadoLibre Keep listings synchronized automatically Manage MercadoLibre publication status from within the platform Scope of Work 1. MercadoLibre Account Connection Inside the dealership account settings, add a new section where users can: Connect their MercadoLibre Uruguay account Authenticate through MercadoLibre API Store the linked MercadoLibre account securely Maintain synchronization between Carmetric and MercadoLibre The integration must follow MercadoLibre API best practices and authentication flow. 2. Publish Vehicles to MercadoLibre When a dealership publishes a vehicle in Carmetric, they should have the option to: Also publish the vehicle on MercadoLibre Send all required listing data through the MercadoLibre API Upload vehicle information, images, features, specifications, etc. Keep the MercadoLibre listing synchronized with Carmetric If a vehicle is edited in Carmetric, the MercadoLibre listing must also update automatically. 3. MercadoLibre Publication Type Selection When enabling MercadoLibre publication, the user must be able to select the publication type: Silver (Plata) Gold (Oro) Gold Premium (Oro Premium) The selected listing type must be sent correctly through the API. 4. Synchronization Status in Listings Index In the vehicle listings table/index, display the MercadoLibre synchronization status, such as: Sent Published Rejected Not synchronized This allows dealerships to easily identify synchronized listings. 5. MercadoLibre Taxonomy Synchronization The module must import and keep synchronized the vehicle taxonomies/categories used by MercadoLibre, including for example: Vehicle brands Models Years Versions Features/accessories Other required vehicle attributes These taxonomies should be available inside Carmetric when creating/editing listings, avoiding manual data entry. 6. Listing Activation / Deactivation Synchronization The module must properly synchronize listing states: If a listing is disabled in Carmetric → disable it in MercadoLibre If a listing is reactivated in Carmetric → reactivate it in MercadoLibre 7. Listing Deletion Synchronization If a synchronized vehicle listing is deleted in Carmetric: It must also be removed/deleted from MercadoLibre 8. Subscription System Compatibility The current platform already has a subscription system. The module must respect existing subscription restrictions: Users without an active subscription cannot publish vehicles This restriction must apply both: to the main dealership account and to dealership sales agents/employees 9. Sales Agent Compatibility The MercadoLibre synchronization and publication features must also work for dealership sales agents (sub-users/employees associated with the main dealership account). Technical Requirements Strong experience with: Laravel REST APIs OAuth/API authentication Background jobs/queues Webhooks and synchronization systems Experience integrating with third-party marketplaces/APIs Ability to work on and extend an existing Laravel application Clean and maintainable code Important Notes The platform is already fully functional Existing dealership, subscription, and agent systems are already implemented The application language is Spanish, but: No translation/localization work is required for this project Nice to Have Previous experience with MercadoLibre API Experience with marketplace integrations Experience handling synchronization conflicts and API rate limits Deliverables Fully functional MercadoLibre integration module Synchronization system between Carmetric and MercadoLibre Clean code integrated into the existing platform Documentation for configuration and maintenance

As an experienced Laravel developer with a strong track record in integrating third-party APIs, I am confident in my ability to seamlessly extend your existing Carmetric platform with MercadoLibre Uruguay. Having previously dealt with OAuth and API authentication, I understand the importance of handling users' MercadoLibre credentials securely. My proficiency with REST APIs will assure smooth synchronization between Carmetric and MercadoLibre accounts, ensuring that dealerships are able to publish vehicles to both platforms simultaneously and manage publication status from within Carmetric. Moreover, I have a keen eye for detail which fits perfectly with your vision to incorporate 'Silver', 'Gold', and 'Gold Premium' listing types, all of which will be accurately conveyed through the MercadoLibre API. Accurate data handling is something I view as paramount for both user experience and system efficiency, and it's a key skillset that I bring to the table. Lastly, my familiarity with maintaining existing codebases and subscription systems makes me an ideal fit for your project. I can confidently navigate the intricate subscription restrictions to ensure effective compatibility for all users, including dealership sales agents. Consequently, I believe my skills in Laravel, REST APIs, OAuth/API authentication, background jobs/queues as well as my experience integrating third-party marketplaces/APIs make me the perfect candidate for this job.

Hello, Your Carmetric MercadoLibre integration is exactly the kind of marketplace synchronization system we specialize in at Doomshell. We understand this is not a simple API connection; it’s a deep Laravel module extension requiring synchronization logic, OAuth flows, background jobs, taxonomy mapping, subscription compatibility, and real-time listing management inside an existing dealership platform. We can help implement: ✔ MercadoLibre Uruguay OAuth/API integration ✔ Dealership account linking & secure token storage ✔ Vehicle publishing from Carmetric → MercadoLibre ✔ Automatic listing synchronization & updates ✔ Publication type handling (Silver/Gold/Gold Premium) ✔ Listing status tracking inside Carmetric ✔ MercadoLibre taxonomy/category synchronization ✔ Vehicle brand/model/version/attribute syncing Why Doomshell? • Strong Laravel & REST API integration expertise • Experience with marketplace synchronization systems • Background jobs, queues & webhook workflow knowledge • Ability to extend large existing Laravel applications cleanly • Long-term support & maintenance availability A few quick questions: 1. Which Laravel version is Carmetric currently running on? 2. Is the platform already using queues/workers (Redis/Horizon/Supervisor), or should we help architect the async sync layer too? 3. Should MercadoLibre synchronization happen instantly on save, or through queued background processing for stability? Regards

Hi I have strong Laravel experience building marketplace integrations, OAuth connections, REST API modules, queue-based synchronization, and admin/dealership workflow extensions inside existing platforms. The main technical challenge here is keeping Carmetric vehicle listings, MercadoLibre account authentication, taxonomy data, publication types, listing states, and subscription restrictions synchronized without disrupting the current dealership system. I can build the MercadoLibre Uruguay connection flow inside dealership settings, securely store API tokens, and integrate vehicle publishing through the MercadoLibre API. When vehicles are created, edited, disabled, reactivated, or deleted in Carmetric, I can trigger Laravel jobs to update MercadoLibre reliably with status tracking and error handling. I can also implement taxonomy synchronization for brands, models, years, versions, features, and required attributes so dealerships can avoid duplicate manual entry. The module will respect existing subscription rules and support both main dealership accounts and sales agent users with clean permissions, maintainable code, and configuration documentation. Thanks, Hercules

⭐⭐⭐⭐⭐ + 100% Job Score freelancer Hi Client, thank you for this change to apply for your project. I'd be a strong fit for your Carmetric–MercadoLibre integration. I've built several Laravel modules that plug into existing codebases without disrupting current workflows, which is exactly what this project needs. For the account connection piece, I'd implement MercadoLibre's OAuth 2.0 flow and store tokens securely, with automatic refresh handling so dealerships stay connected. Vehicle publishing and edits would sync through the MercadoLibre API using queued background jobs, so the platform stays responsive even when pushing listings, images, and specs. I'd wire up webhooks to keep listing status (Sent, Published, Rejected) accurate in your index in near real time, and handle activation, deactivation, and deletion as proper state syncs in both directions. I'd also build the taxonomy sync (brands, models, years, versions, features) as a scheduled job so your team never enters that data manually, and respect your existing subscription rules and sales-agent permissions rather than working around them. I'm comfortable handling API rate limits and sync conflicts, which tend to be where marketplace integrations get messy. I work clean, document as I go, and would integrate everything into your current structure rather than bolting something on the side. Happy to walk through my approach in more detail. Looking forward to hearing from you. Best, Vinh

Hello, your description of extending Carmetric’s existing Laravel workflow with full MercadoLibre Uruguay synchronization shows you need someone who can work inside a mature codebase without breaking existing dealership, subscription, or agent logic. I’ve delivered similar marketplace integrations before, including a Laravel module that synced vehicle listings with an external classifieds API and kept states aligned through webhooks and queued jobs. I see the real challenge here is maintaining consistent synchronization between Carmetric and MercadoLibre while respecting subscription boundaries and handling listing lifecycle changes. The taxonomy import and periodic updates also require careful queue design to avoid rate‑limit issues. I’ll implement the OAuth flow, account‑linking section, listing publication pipeline, taxonomy synchronization, and all state‑change handlers directly within your current architecture. I’ll use jobs, observers, and clear service classes to keep changes isolated and maintainable. Before starting, I need clarity on your current queue setup and whether webhooks are already configured for external integrations. I can deliver the full module in a clean, staged rollout. Best regards, John allen.

I can extend your Carmetric platform to integrate MercadoLibre Uruguay smoothly, letting dealerships sync listings directly through the MercadoLibre API. I've done similar marketplace integrations where I connected existing Laravel apps to third-party APIs, syncing item data and images automatically. My plan is to build the MercadoLibre account connection in settings with secure OAuth authentication. Then I’ll extend vehicle publishing workflows so dealerships can push listings and updates to MercadoLibre, including correct publication types like Plata, Oro, and Oro Premium. I’ll ensure real-time sync for listing status, activation, and deletions. Also, I’ll import MercadoLibre vehicle taxonomies so dealers can choose brands and models without manual input, keeping these categories up to date automatically. Questions: Do you have API credentials ready for testing on a MercadoLibre sandbox? And should synchronization operate via queued jobs or webhooks, or a mix for reliability? This is a straightforward sync scenario I can deliver efficiently within your existing Laravel codebase. Ready to start building this module and keep Carmetric’s workflow seamless with MercadoLibre.
