Backend Developer Needed Multi-Service Delivery Platform

@kamran2012

Interesting project, I will deliver your Milestone 1 — Docker environment, JWT auth with RBAC, Prisma migrations, and the core APIs for merchants, drivers, and delivery orders — along with the pricing engine, driver recommendation logic, and full Swagger docs. For the multi-service architecture, I will structure each domain (shipping, eats, supply) as isolated NestJS modules behind a shared service registry, so adding BlessEats or BlessSupply later means plugging in a new module without refactoring existing code. The pricing engine will use a strategy pattern — making it straightforward to swap distance/weight/GST rules per service type. Questions: 1) For the driver recommendation engine, what factors matter most — proximity, rating, current load, or a weighted combination? Looking forward to discussing further. Best regards, Kamran

Having over 5 years of full stack, I would be a great fit for your project. In particular, I have significant experience working with complex back-end solutions using technologies similar to the ones you've outlined in the project description. My expertise in NestJS and proficiency with Prisma/PostgreSQL aligns perfectly with your requirement for a scalable, modular architecture capable of handling multiple services. Moreover, as an experienced Docker and Github user, I understand how crucial it is to maintain organized and well-documented codebases in collaborative projects like yours. My clean and optimized approach towards coding aligns perfectly with your emphasis on maintainability and scalability. Lastly, I'm also experienced in API integration, database management, performance optimization - all skills that will prove vital in your long-term project requirements beyond just Milestone 1. I believe my ability to deliver high-quality work promptly while maintaining transparent communication makes me the ideal candidate for this multi-service delivery platform project. I look forward to discussing the details of your project further and collaborating with you on what could be an amazing product!

Hi. I’ve built NestJS backends with PostgreSQL, Prisma, Redis, and Docker, so your Milestone 1 scope is very familiar. I can deliver a clean, modular setup with JWT, RBAC, pricing logic, and a working Docker environment ready to run. I’ll keep commits consistent and provide clear docs for handoff. Let’s discuss timeline.

Hi, This project is essentially about building a modular delivery backend where core logic must stay independent so future services like food delivery and marketplace can be added without rewriting the system. I’ve worked on NestJS + Prisma + PostgreSQL systems with Docker, RBAC, and modular domain-based architecture in production environments, and I’m comfortable owning this backend end-to-end. For Milestone 1, I will deliver a fully Dockerized system where: • `docker compose up` runs API, DB, and migrations with zero manual setup • Clean modular architecture (merchants, drivers, orders, pricing) • JWT authentication with RBAC • Prisma schema designed for future multi-service scaling • REST APIs for core workflows • Redis integration for performance + driver assignment • Swagger documentation • Clean, incremental Git commits structured for review Everything will be built so BlessShipping runs independently, while remaining extendable for future services without core refactoring. Timeline: ~2–3 weeks after final scope confirmation. One question: should I design the Prisma schema from scratch, or extend an existing model? Lets discuss. Regards, Abhishek

I understand you need a backend developer experienced with NestJS, PostgreSQL, and Docker to build the core architecture for your multi-service delivery platform, prioritizing extensibility for services like BlessShipping and BlessEats. I recently developed a microservices backend for a logistics company, successfully handling real-time order tracking and dispatching, which mirrors the core requirements of your BlessPlatform. My approach will involve creating modular services within a NestJS microservices architecture, utilizing Prisma ORM for robust PostgreSQL data management and Redis for efficient caching. I'll implement JWT authentication and RBAC for secure access control, ensuring each service is containerized with Docker and orchestrated using Docker Compose. This will result in a well-defined API documented with Swagger, ready for immediate integration. What is the expected user load and transaction volume for the MVP phase of BlessShipping? Ready to start as soon as you confirm scope.

Hi there! I’m really excited about the opportunity to work on your multi-service delivery platform! The challenge of creating a scalable architecture that remains service-independent is right up my alley. I recently tackled a project that involved building a modular e-commerce platform using NestJS and PostgreSQL, which required similar foresight for future expansions. One distinctive feature I implemented was an intelligent pricing engine that adjusted rates based on real-time variables like distance and service demand, integrating seamlessly with the overall architecture. I believe this kind of forward-thinking approach can add significant value to your BlessShipping MVP. Regarding your request for relevant experience, I’ve successfully completed several projects using NestJS and PostgreSQL, and you can check my GitHub for continuous commits and clean code practices. I’m curious about how you envision the driver recommendation engine working—are there specific metrics you plan to use? Let’s hop on a quick Zoom call this week to dive deeper into your vision! Looking forward to it, Artem

Hi, I am an IITian with 10+ years of experience to develop similar projects ,I will architect a service-oriented monolith using NestJS with modular boundaries for BlessShipping, BlessEats, and BlessSupply, leveraging Prisma ORM with PostgreSQL (multi-tenant schema via discriminator columns and service-scoped contexts). Auth will use JWT with passport-jwt and RBAC via custom NestJS guards, Redis for session caching and rate limiting, all containerized with Docker Compose for local dev and production-ready with health checks and migrations via Prisma Migrate.

Your requirement for a NestJS backend developer with PostgreSQL and Docker expertise for your multi-service delivery platform immediately caught my eye. I've successfully architected and implemented similar microservice-based systems, ensuring loose coupling and scalability, which is crucial for platforms like BlessPlatform Core aiming to support diverse services like BlessShipping and BlessEats. My approach prioritizes robust, maintainable code that can adapt to future expansion. My technical strategy would involve leveraging NestJS's modular architecture and dependency injection for clean service separation. PostgreSQL, coupled with Prisma ORM, will provide a powerful and type-safe data layer. We'll utilize Docker and Docker Compose for consistent development and deployment environments, ensuring seamless integration. For authentication and authorization, I'll implement JWT with RBAC for granular access control. I'll also integrate Swagger for comprehensive API documentation. To best align with your vision, could you elaborate on the specific performance benchmarks you're targeting for the MVP? Additionally, what are your primary considerations regarding data consistency across the different delivery services as they evolve? I'm eager to discuss how my skills can directly contribute to the success of BlessPlatform Core.

Hi, Most developers will build APIs. I build the system that survives growth. I've built TMS, WMS, courier, freight forwarding, ERP, and CRM platforms, so the logic behind drivers, deliveries, pricing, and operations is familiar territory. https://www.freelancer.in/u/SJMDEVELOPER ✔ NestJS + PostgreSQL + Prisma ✔ JWT & RBAC ✔ Driver, Merchant & Delivery APIs ✔ Pricing & Assignment Engine ✔ Dockerized Deployment ✔ Clean Architecture for Future Services The goal isn't to launch BlessShipping. The goal is to build the foundation for BlessEats, BlessSupply, and everything that comes next. Let's discuss Milestone 1, and I'll put together a roadmap, timeline, and fixed-price proposal.
