Your NestJS microservices will bottleneck at 500 concurrent users if you're not implementing connection pooling and query optimization from day one. I've seen real-estate platforms crash during open house listings because the database wasn't tuned for burst traffic. Before we architect the solution, I need clarity on two things: What's your expected peak load—are we talking 5K or 50K concurrent API requests? And does your data model require multi-tenancy isolation at the database level, or can we use row-level security in PostgreSQL? Here's the architectural approach: - NODE.JS + NESTJS: Build a modular microservice architecture with dependency injection, custom decorators for auth guards, and structured logging that traces requests across services in under 100ms. - POSTGRESQL + PRISMA: Design a normalized schema with proper indexing on foreign keys and search fields, implement connection pooling through PgBouncer, and set up read replicas to offload reporting queries from transactional workloads. - AWS INFRASTRUCTURE: Deploy on ECS Fargate for auto-scaling containers, use RDS with automated backups and point-in-time recovery, store property images in S3 with CloudFront CDN, and trigger Lambda functions for async tasks like PDF generation. - REDIS + BULL: Cache frequently accessed listings and user sessions in Redis, implement Bull queues for email notifications and image processing to prevent API timeouts during heavy operations. - CI/CD PIPELINE: Set up GitHub Actions to run Prisma migrations, execute Jest unit tests, build Docker images, and deploy to staging/production with zero-downtime rolling updates. I've built 4 property tech platforms that scaled from MVP to 100K+ listings without rewriting the core architecture. I don't take on projects where performance requirements are vague—let's schedule a 20-minute call to walk through your data model and traffic projections before I commit to a timeline.

Hi, I am senior software developer With 14+ years of experience,. I have built high-performance APIs using Node.js, NestJS, PostgreSQL (Prisma) and deployed scalable systems on AWS. I can design clean, versioned microservices, optimize database schemas, and ensure APIs are fast, secure, and production-ready. I also work with Redis, Bull/RabbitMQ, and Docker-based deployments with CI/CD pipelines. I follow best practices—modular architecture, clean code, proper validation, and testing—so your system scales without technical debt. I am comfortable collaborating closely with frontend teams, providing clear updates, and pushing consistent Git commits. Availability: Immediate Quick questions: 1. Do you already have a base NestJS structure or starting from scratch? 2. Expected traffic/load at launch? 3. Preferred AWS setup (EC2 vs containerized ECS)? Ready to jump in and deliver fast. Best regards, Jitendra Sharma

@hockfx

You need a seasoned backend expert to design and implement high-performance REST APIs for your real-estate platform, ensuring they are clean, versioned, and scalable. I will start by shaping the database schema in PostgreSQL using Prisma ORM, ensuring data integrity and clean migrations. Next, I will develop the APIs in Node.js with NestJS, focusing on writing clean, testable code that can handle high loads. For deployment, I will containerize the application using Docker and set up a CI/CD pipeline to automate deployments, ensuring fast iterations without downtime. Additionally, I can implement Redis for caching or RabbitMQ for queuing to enhance performance. Timeline: 4 days. Can you confirm if you have existing infrastructure on AWS or if I will need to set it up from scratch?
