Hi, This is Elias from Miami. I've worked on enterprise-grade platforms involving Vue, Java/Spring ecosystems, payment integrations, complex product catalogs, role-based administration, and API-driven architectures. I’d approach this by preserving the domain-driven separation already established, focusing on maintainable modules, strong API contracts, security compliance, and scalable integration patterns for SAP, payments, and future AI orchestration layers. I have a few questions to get a better understanding: Q1 – Which role are you primarily hiring for right now: Vue frontend, Spring Boot backend, or payment integration specialist? Q2 – Has the product configurator domain model already been finalized, or is that still evolving? Q3 – Will MongoDB serve only catalog/configuration data, or will search and recommendation features also depend on it? I'd be happy to discuss the details and suggest the best approach for implementation. Looking forward to hearing from you.

Hello, I understand you are building a security-focused international e-commerce platform for complex bathroom products using Vue 3, Spring Boot, MySQL, MongoDB, SAP integration, and multiple payment gateways, with strong emphasis on scalability, modularity, multilingual commerce, and long-term maintainability. I have experience developing enterprise-grade e-commerce systems with Vue 3 Composition API, Pinia, Spring Boot, REST integrations, hybrid SQL/NoSQL architectures, secure JWT authentication, payment gateway integrations, and complex product configuration workflows. I can contribute across the frontend and backend layers, implementing clean architecture, secure integrations, configurable product logic, multilingual features, payment processing, and scalable code aligned with your phased development and security standards. Q1: Which role is the immediate priority: Vue 3 Frontend, Spring Boot Backend, or Payment Integration Specialist? Q2: Is the SAP R/3 REST integration already available, or does it need to be designed and implemented as part of the project? Q3: What phase is currently underway—foundation completion, catalog/configurator development, payments, or marketplace launch preparation? Best regards, Stratos

The tricky part here isn't the storefront — it's the configurator. A single-door screen exposes opening position while a double-door doesn't, so I'd drive the whole form from the configurator endpoint instead of hardcoding any attribute. Each product type returns its own fields, allowed values, and constraints, and the UI renders from that schema — add a category in the back office and the frontend just works, no redeploy. I'd start with Pinia stores for catalog, cart, and a market store holding country/locale/VAT, with vue-i18n keyed off it so ES/FR/DE/EN and pricing stay aligned. Then the schema-driven configurator, then checkout. Since the JWT sits in an HttpOnly cookie the frontend can't read, I'd track session via a /me call and send cookies with withCredentials — never localStorage. I did similar dynamic forms and multilingual flows on Bubbl (Vue 3 / Nuxt 3). One thing worth confirming: should the UI block invalid attribute combos live, or rely on backend validation? Happy to start on the catalog and configurator.

Your platform needs engineering depth, not a generic storefront. I would focus on the Vue 3 frontend, Spring Boot backend, hybrid catalog model, SAP integration, and payment/security requirements as one coherent architecture. My approach would be to take ownership of a defined module or role, then deliver clean milestones against your existing hardened foundation: Vue 3/Pinia/i18n frontend work, Spring Boot Java 21 services, MySQL/MongoDB catalog logic, SAP REST sync, or payment flows for Redsys, Stripe, and Aplazame. I would focus on: - Vue 3 components, product configurator states, i18n, and secure JWT handling - Spring Boot APIs, domain boundaries, MySQL/MongoDB consistency, and tests - SAP R/3 REST integration, payment edge cases, and audit-friendly logging - Code review, CI, documentation, and production-readiness checks I can start with the highest-risk module and define acceptance tests before implementation. Best, Dr. Syafiq

Hi I can contribute to your international e-commerce platform with strong experience in Vue 3, Spring Boot, secure API architecture, hybrid databases, and payment gateway integrations. The main technical challenge is keeping the product configurator, multilingual storefront, SAP synchronization, payments, and admin workflows modular while maintaining strict security and performance standards. My solution would be to work within your existing hardened foundation, follow clean domain boundaries, and implement features with scalable Vue 3 Composition API components, Pinia state management, and secure backend APIs. I also have experience with Java, Spring Security, JWT authentication, MySQL, MongoDB, REST integrations, Stripe, complex catalog modeling, and enterprise-grade business logic. For the frontend, I can help build dynamic product configuration, i18n flows, secure session handling, and back-office modules that remain maintainable across Spanish, French, German, and UK markets. For the backend, I can support SQL/NoSQL data modeling, SAP R/3 integration, role-based access, transactional workflows, and payment-ready API design. I can also assist with Redsys, Stripe, and financing gateway logic while respecting PCI-DSS principles and secure token/payment handling. I focus on clean code, strong security, clear documentation, and long-term maintainability for future agentic AI automation. Thanks, Hercules

The agentic AI layer — designed to operate the platform autonomously once the initial phases are complete — is the element in this brief that most directly aligns with my work. Where I fit in this project: - SAP R/3 REST integration: I work regularly with REST-based ERP connectors and can own the master data sync layer, including entity mapping between SAP and your hybrid MySQL/MongoDB model. - Payment gateway abstraction: Redsys SHA-256 flow, Stripe webhooks, and Aplazame's financing API each have distinct reconciliation patterns; a unified orchestration layer insulates the domain model from provider specifics. - Agentic AI architecture: what operations are in scope for autonomous execution — order routing, inventory replenishment, pricing, customer support? The answer drives the agent design significantly, and the brief does not define it yet. Three weeks is realistic for the integration and AI scaffolding scope. Treat this amount as an initial, orientative reference for the scope described — not a final price; we will confirm the exact figure once we clarify the autonomous operations and integration depth. Happy to have a quick 15-minute call here on Freelancer to walk through the open points — feel free to browse my profile and portfolio there as well.

Hello, This is a serious enterprise-grade build—Vue 3 + Spring Boot with hybrid MySQL/MongoDB, SAP integration, and multi-gateway payments. The architecture-first approach is exactly right for this level of complexity. I understand the goal is a scalable EU e-commerce platform with strong security, clean domain separation, and flexible product configurator support, not just a standard store. I specialize in Spring Boot (DDD architecture), secure JWT-based systems, hybrid databases, and Vue 3 (Pinia, Composition API). I’ve also built systems involving complex APIs and modular admin dashboards. I would structure this with: Clean Spring Boot modular backend (catalog, orders, payments, SAP) MySQL for transactions + MongoDB for dynamic catalog/configurator Vue 3 frontend with i18n + Pinia + configurator UI Isolated payment layer (Stripe, Redsys, Aplazame) Secure layered auth (JWT, RBAC, HttpOnly cookies) If helpful, I can first map a clear architecture + phased delivery plan before development starts. Quick question—do you want to start with backend foundation first or full-stack parallel sprinting? Lets discuss. Regards Abhishek

@kishanbwts

I can help build the Vue 3 frontend with the dynamic product configurator and multilingual support you need. In a past project for a European home goods seller, I developed a similar configurator that handled multiple variable attributes smoothly and integrated i18n for four languages, improving user experience and admin control. To securely manage JWT tokens as you require, I’d suggest using HttpOnly cookies combined with Pinia stores for state management. Have you planned how the configurator will sync complex product attribute changes in real time? I can implement an efficient reactive system for this. The multilingual admin back office can also benefit from modular Vue 3 components for scalability as you add markets. I’m ready to start implementing these features with clean, secure code that fits your phased rollout.

Your hybrid MySQL/MongoDB architecture will create data consistency issues if you don't implement a distributed transaction pattern. Without proper saga orchestration, you'll face orphaned records when SAP sync fails mid-transaction. Quick question - what's your strategy for handling product catalog updates when MongoDB and MySQL fall out of sync? And does your SAP R/3 instance support real-time webhooks or are you polling for changes? Here's the architectural approach: - SPRING BOOT + HYBRID DB: Implement the Outbox pattern with Debezium CDC to guarantee eventual consistency between MySQL transactions and MongoDB catalog updates, preventing data corruption during SAP synchronization failures. - VUE 3 COMPOSITION API: Build a reactive product configurator using Pinia stores with optimistic UI updates and rollback logic, reducing perceived load time by 70% even with complex attribute dependencies. - PAYMENT INTEGRATION: Set up idempotent webhook handlers for Redsys/Stripe with Redis-based deduplication to prevent double charges during network retries, plus implement PSD2-compliant SCA flows. - JWT + SPRING SECURITY: Configure refresh token rotation with Redis session store and implement CSRF protection for state-changing operations, meeting PCI-DSS session management requirements. - SAP R/3 REST API: Design a resilient integration layer with circuit breakers and exponential backoff to handle SAP downtime without blocking checkout flows. I've built 3 similar multi-payment e-commerce platforms that processed €2M+ monthly. Let's schedule a technical call to discuss your SAP data model and transaction boundaries before finalizing the architecture.

@techsty2014

Hey, We will build your Vue 3 frontend, Spring Boot backend, and payment layer as a unified, modular system tuned for multi-market bathroom product sales. For the hybrid database model, we will map transactional flows (orders, users, payments) to MySQL while storing the configurable product catalog in MongoDB. This split lets the product configurator query flexible attribute structures without slowing checkout operations. The SAP R/3 sync will run on a scheduled reconciliation loop with conflict detection. A couple of quick things to confirm: 1) For the Redsys integration, will you provide an existing merchant test environment, or do we need to set that up? 2) Is the Vue 3 admin back office a separate SPA, or will it live within the same frontend codebase behind role gates? Looking forward to potentially working together. Thanks, Faizan

@AndrewJSMAN

I’ve built hybrid Spring Boot/Vue stacks with Redsys, Stripe and MongoDB/MySQL for e-commerce before—this is right in my wheelhouse. My approach: I’ll scaffold a Spring Boot 3.2 REST layer with JWT over HttpOnly cookies, route Redsys transactions through SHA-256 HMAC in Spring Integration, and wire Stripe via direct API calls with idempotency keys. Frontend will be a Vue 3 Composition API app using Pinia stores for cart state and vue-i18n for ES/EN/DE/FR locales, consuming the backend via typed Axios interceptors. MongoDB will host the polymorphic product catalog with MySQL for orders, inventory and user sessions locked to the same transaction boundary. I’ll run end-to-end regression tests against SAP R/3 mocks before locking the deployment pipeline to zero-downtime blue-green releases. I can start immediately.

@aprkdream

Hi, I'm excited to help you develop a high-performance e-commerce platform for your complex bathroom products. I understand that you're looking for a scalable, modular, and international platform, with a focus on variable attributes, multilingual support, and a dynamic product configurator. You've also mentioned a long-term vision to integrate agentic AI for autonomous operation. From my analysis, I believe the technical pillars you've outlined are a good foundation. I'd like to propose a complementary approach that combines the strengths of Spring Boot and Vue 3 with my expertise in Laravel and Node.js. I'd start by setting up a clean and decoupled backend using Laravel's Eloquent ORM, which would allow for seamless integration with your existing MySQL database. For the frontend, I'd suggest using React.js in conjunction with Vue 3 to leverage its powerful features and dynamic product configurator. To address the complexity of your product offerings, I'd recommend implementing a robust product information management system (PIM) using Laravel's Octane package. This would enable efficient management of product attributes, pricing, and inventory levels across multiple languages and markets. In terms of AI integration, I'd propose starting with a chatbot development using Laravel's BotMan package, which would allow for seamless integration with your existing backend and frontend infrastructure. This would provide a solid foundation for future AI-powered features and autonomous operation. I'd also like to clarify that you've mentioned using Spring Boot for the backend, but it seems like you're open to alternative technologies. Could you provide more information on why you've chosen Spring Boot, and if there are any specific requirements or constraints that need to be addressed? I'm confident that with my expertise and a collaborative approach, we can deliver a high-performance e-commerce platform that meets your needs and exceeds your expectations. I'm excited to discuss this proposal in more detail and explore how we can work together to bring your vision to life.
