Senior ERP Developer / Engineer (React/NextJs + Node.js/NestJs)

@vishal1145

Your ERP system will fail during month-end closing if MongoDB isn't properly indexed for high-volume transaction queries. I've seen manufacturing ERPs grind to a halt when inventory reconciliation hits 50K+ SKUs without proper database optimization and caching strategies. Before architecting the solution, I need clarity on two things - What's your current transaction volume during peak production cycles, and are you planning to support multi-plant operations with real-time inventory sync? This determines whether we need event sourcing with message queues or can work with traditional REST patterns. Here's the architectural approach: - REACT + NEXTJS: Build server-side rendered dashboards with incremental static regeneration for production reports, cutting load times from 4s to under 500ms even with complex manufacturing analytics. - NESTJS + MICROSERVICES: Design domain-driven modules (procurement, inventory, production planning) with GraphQL federation so each manufacturing workflow scales independently without monolithic bottlenecks. - MONGODB + POSTGRESQL: Implement polyglot persistence - transactional data in PostgreSQL with ACID guarantees, real-time IoT sensor data and audit logs in MongoDB with time-series collections optimized for manufacturing telemetry. - AWS INFRASTRUCTURE: Set up ECS Fargate for auto-scaling backend services, RDS read replicas for reporting queries, and ElastiCache to handle concurrent user sessions during shift changes without database strain. - ERP WORKFLOWS: I've built 3 manufacturing ERPs handling BOM explosions, work order routing, and shop floor data collection with barcode integration - I know where the edge cases hide in multi-level assemblies and scrap tracking. I bring 12+ years building enterprise systems that don't collapse under production load. I've worked with precision manufacturing clients where system downtime costs $10K per hour - reliability isn't optional. Let's schedule a technical call to walk through your current pain points and module priorities before committing to architecture decisions.

Hi, This role aligns very closely with my experience. I have 12+ years in software development, with strong expertise in React.js/Next.js, Node.js, and NestJS, and I have built scalable ERP-style systems with complex workflows and role-based architectures. I have worked extensively with both SQL (PostgreSQL/MySQL) and MongoDB, designing high-performance APIs and microservices. I am also experienced with AWS (EC2, S3, RDS, Lambda) and system architecture, ensuring scalability, security, and reliability for enterprise applications. I can contribute across the full lifecycle—architecture, module development (inventory, production, orders), performance optimization, and mentoring junior developers. I’m comfortable working with cross-functional teams and translating manufacturing workflows into efficient digital systems. Before we proceed I have some quick Questions: Q1-- Are you building a new ERP from scratch or enhancing an existing system? Q2-- Which core modules are the immediate priority (inventory, production, procurement, etc.)? Q3-- Do you already have a defined architecture (monolith vs microservices) or should I help design it? I am ready to contribute immediately and deliver scalable, production-grade ERP solutions. Thanks, Jitendra Sharma

Hi, Sahanaj here. I’ve built manufacturing-focused ERP systems using React/Next + Node/NestJS with SQL/Mongo and AWS, including scalable microservices. Your budget is low for a senior role. A fair range is ₹2,500/hr or ₹2.5L–₹3.5L/month for enterprise-grade delivery. I can design robust ERP modules, optimize performance, and align workflows with manufacturing needs. One question: which core modules are priority (production planning, inventory, procurement, or quality control)?

Hi Balaji, The main challenge here isn't just building an ERP - it's architecting a scalable manufacturing-focused system that handles amplu workflows. inventory tracking, production planning. real-time data sync across modules. I've built 28+ React/Next. js applications in the last 2 years. including full-stack dashboards with Node. js backends, MongoDB databases, and GraphQL APIs. my experience spans inventory management systems, automation platforms, and data-heavy applications that require solid architecture and performance improvement. For this ERP, I'll use Next. js 14 with App Router for the frontend. NestJS for the backend API layer, MongoDB for flexible data modeling, and GraphQL for fast data fetching. The architecture will be modular - separate services for inventory, production, orders, and reporting - making it maintainable and scalable. I'm offering a competitive rate to build my Freelancer portfolio with quality reviews. I work extremely fast using advanced development workflows and can deliver production-ready code in days, not weeks.

@Areebmehdi110

Hi, I recently built and shipped BLP HRMS — a complete HR management system (React Native mobile + React.js web + Python/Flask backend) covering attendance, payroll, leave management, and employee lifecycle. Enterprise-grade, modular, production-ready. Your manufacturing ERP needs the same foundation, and I already have it battle-tested. My approach: → Frontend: React.js/Next.js with modular dashboards for production, procurement, QC. React Native ready for shop-floor mobile access. → Backend: Python/Flask with Blueprints — each ERP domain (BOM, work orders, invoicing, dispatch) as a clean, independent module. Python's data libraries mean built-in analytics and reporting. → Database: PostgreSQL + MongoDB → Cloud: AWS (EC2, RDS, S3) Why me: • Shipped a complete enterprise system — not just components • I understand ERP workflows: approvals, role hierarchies, audit trails • Clean, documented, scalable code Happy to walk you through my HRMS project on a call.
