Full-Stack Developer Needed for Multi-Vendor Marketplace (Angular + Spring Boot + AWS)

@Microlent

Hello! I understand you want to extend your existing Angular + Spring Boot e-commerce platform into a multi-vendor marketplace (Amazon-style MVP) with Admin, Seller, and User panels, secure APIs, and AWS deployment. Approach I will extend the current architecture while keeping your existing product, cart, checkout, and Stripe flow stable. Key Work • Implement JWT authentication with role-based access (ADMIN, SELLER, USER) • Build Seller Panel for product management, inventory, orders, and revenue overview • Develop Admin Panel for seller approvals, product moderation, marketplace commissions, and analytics • Update database schema (sellers, product_images, commissions, payouts, order_items) • Secure REST APIs with validation and error handling AWS Deployment • Angular build on S3 + CloudFront • Spring Boot backend on Elastic Beanstalk or EC2 • RDS MySQL database • SSL via AWS Certificate Manager DevOps • Dockerized backend • CI/CD pipeline using GitHub + Jenkins I’d be happy to review the current codebase and define precise milestones. Best regards, Jasmin

Hi there, I will extend your existing Angular + Spring Boot e-commerce platform into a full multi-vendor marketplace with Admin, Seller, and User panels, role-based JWT security, Stripe commission logic, and complete AWS deployment. Here is how I will approach this: **Phase 1** - Database restructuring and role-based API layer (sellers, commissions, payouts, product approval workflow) **Phase 2** - Seller panel and Admin panel with dashboards, product moderation, and order management **Phase 3** - Stripe split logic with marketplace commission per order **Phase 4** - AWS deployment (S3 + CloudFront for Angular, Elastic Beanstalk for Spring Boot, RDS MySQL), Docker setup, and Jenkins CI/CD pipeline For the seller payout tracking, I will build an admin-facing ledger that calculates commission per order and tracks pending versus completed payouts, keeping it simple for MVP but structured for future Stripe Connect integration. We have delivered similar marketplace platforms with multi-role panels and AWS infrastructure. I can start immediately and target delivery within 4 weeks with weekly milestone demos. Questions: 1) Is the existing codebase in a GitHub repository, and do you have the current database schema documented? 2) Do you have an AWS account already configured, or should infrastructure setup be included from scratch? Thanks and best regards, Kamran

Hello, I can extend your existing Angular + Spring Boot e-commerce platform into a full multi-vendor marketplace MVP. This includes Admin, Seller, and User panels with role-based JWT authentication, Stripe payments, product approval workflows, commission handling, and order management. The database will be updated to support sellers, products, images, orders, commissions, and payouts. Frontend and backend will be deployed on AWS (S3 + CloudFront + Elastic Beanstalk/EC2 + RDS MySQL) with Dockerized services and CI/CD pipelines via GitHub + Jenkins. Deliverables include full source code, database schema, API documentation, deployment instructions, and CI/CD setup. The platform will be secure, scalable, and ready for production, with manual seller payouts handled by the admin in the MVP. Clarification questions: Should seller applications and product approvals be fully manual via the admin panel, or partially automated with notifications? Are there preferred analytics metrics or dashboards to include in the MVP admin panel, or basic sales/revenue overviews suffice? Thanks, Asif

Hello! As per your project post, you’re looking to extend your existing e-commerce platform into a multi-vendor marketplace similar to Amazon, featuring separate Admin, Seller, and User panels, secure APIs, and AWS-based production deployment. The goal is to create a robust MVP that handles product listing, inventory management, order processing, payments via Stripe, and marketplace commission logic while remaining scalable and secure. My focus will be on delivering a full-stack solution using Angular for the frontend and Spring Boot for the backend. The platform will include JWT-based authentication, role-based access control, and separate dashboards for users, sellers, and admins. Sellers can manage products and view their orders while admins oversee approvals, marketplace commission, and payouts. The system will be deployed on AWS with S3, CloudFront, RDS MySQL, and Elastic Beanstalk or EC2, ensuring scalability and reliability. I specialize in Angular + Spring Boot applications with attention to secure REST APIs, responsive frontend design, and modular, maintainable backend architecture. The marketplace will be built for smooth performance, future feature expansion, and operational clarity for both admins and sellers. Let’s connect to define the platform structure, API endpoints, and workflow so we can build a clean, secure, and scalable multi-vendor marketplace. Best regards, Nikita Gupta.

Hi there, I noticed a potential bottleneck in your project that could hinder performance: data synchronization across platforms. I ensure efficient processing by implementing advanced algorithms to deliver seamless integration, reducing lag and enhancing user experience. Not everyone catches this. Recently, I tackled a similar challenge for an e-commerce platform, boosting their data processing speed by 40% and significantly improving customer satisfaction. I include 30 days of post-deployment bug-fixing, so you're covered after the launch. What specific data volume are you anticipating for synchronization? Let's discuss how I can optimize your project.

@devitmd98

Hello, I can extend your existing Angular + Spring Boot + MySQL store into a true multi-vendor marketplace MVP with separate Admin/Seller/User panels, secure JWT + role-based access, and an AWS production setup (S3/CloudFront for the frontend, Spring Boot API on EB/EC2, RDS MySQL). I understand the current platform already has products, cart, checkout, Stripe, and orders, and the main work is adding marketplace roles/workflows (seller onboarding + approval, product approval, seller order views/status updates, commission tracking, admin oversight) without breaking the existing purchase flow. I’d implement the marketplace logic cleanly in the backend first: seller entity + approval state, product “draft/pending/approved” publishing states, order-item ownership per seller, commission calculation per order, and payout records (manual in MVP). Then I’d expose well-structured REST endpoints with proper validation and authorization guards per role, and update the Angular app into three experiences (customer storefront + seller console + admin console) while reusing existing components where possible. If you share your current repo structure and how Stripe is implemented today (Checkout/PaymentIntents, webhooks, order finalization), I can map the commission/payout flow precisely and ensure order state changes remain consistent across admin + seller views. Best regards

I would love to work together to make this project a reality. I greatly appreciate the time provided and I remain pending for any questions or comments. Feel free to contact me. Greetings

@temoberishvili

Hi, The existing foundation (Angular + Spring Boot + MySQL with Stripe and cart/checkout already working) makes this a well-positioned extension rather than a ground-up build. The marketplace layer on top is essentially three things: role-based multi-tenancy (Admin/Seller/User), a product approval workflow, and commission tracking with manual payouts for MVP. For the seller panel, I'd extend the existing Spring Boot entities with a seller registration flow that goes through admin approval, product CRUD scoped to the seller's own inventory, and order views filtered to only their products. The admin panel adds approval queues (sellers and products), commission configuration per order, and a dashboard pulling from the existing order/payment data. On the AWS side, I've deployed this exact stack before — Angular on S3 + CloudFront, Spring Boot on Elastic Beanstalk, RDS MySQL, with Docker and Jenkins CI/CD. SSL via ACM, security groups, and environment variable management are all standard steps I'll configure and document. The milestone structure I'd propose: 1. Database schema extension + role-based auth + seller registration flow 2. Seller panel (product CRUD, order management, revenue view) 3. Admin panel (approvals, commission, dashboard analytics) 4. AWS deployment + Docker + CI/CD pipeline 5. Testing, documentation, and handover Best regards,
