You will get a Multi-Tenant SaaS Backend with NestJS & PostgreSQL

Project details
Most SaaS backends fail before they scale: poor tenant isolation, billing that breaks on edge cases, and architecture that becomes unmaintainable the moment you add a second customer.
I've built a production multi-tenant SaaS platform (Sober House Hub) from scratch; automated Stripe billing, RBAC, Redis queues, background job processing, and complete tenant data isolation. Real users. Real scale. Zero failed launches.
What you get:
✅ Multi-tenant architecture — unlimited organizations
✅ JWT auth + role-based access control (RBAC)
✅ PostgreSQL with complete tenant data isolation
✅ Stripe subscriptions + automated billing engine
✅ Payment retry logic — eliminates manual invoicing
✅ Redis + BullMQ background job processing
✅ Docker-ready + CI/CD pipeline setup
✅ Full API documentation + GitHub delivery
Whether you're launching an MVP or building a production-grade SaaS platform. I'll architect a backend that scales with your business without breaking under real traffic.
Message me with your idea and I'll tell you exactly how I'd structure your system.

About Inam
Sr. Software Engineer | NodeJS, NestJS, Laravel, AI Integration

I've spent the last few years solving exactly these problems. I'm new to Upwork. I'm not new to production systems handling millions of users.
✅ Production Systems I've Built
-- Bolt VPN — 500K–1M daily API calls | 50M+ downloads | 30% latency improvement | AES-256 encryption
-- Sober House Hub — $40–50K monthly transactions | 50+ organizations | 100+ properties | Zero-manual invoicing
-- GPS Family Locator — 99.999% uptime | 2–300K daily requests | Sub-second SOS alerts | AES-256 encryption
-- StepMate — 400K downloads | 1–3K daily active users | Serverless on Cloudflare
-- Veo Football Analysis — AI video analysis | YOLO + REID detection | Gemini analytics | Production-grade
Real users. Real traffic. Real consequences for failure.
✅ What This Means For You
-- Scale: I've handled systems from 1K to 1M+ concurrent requests. I know where performance breaks and how to fix it.
-- Reliability: 99.999% uptime isn't theoretical—it's what I've delivered in production. Every millisecond matters.
-- Security: Encryption, key rotation, threat detection. I don't cut corners on security.
-- Automation: Built automated billing systems processing hundreds of thousands monthly. Zero manual work.
-- AI Integration: Not just ChatGPT plugins. I've integrated computer vision (YOLO, REID) and LLMs where they solve real business problems.
✅ How I Work
-- Production-grade REST APIs with proper auth, RBAC, and full documentation
-- Multi-tenant SaaS architecture with automated billing (Stripe, payment systems)
-- Real-time backends — GPS tracking, live data pipelines, WebSockets, async queues
-- AI/Computer vision integration — Gemini, OpenAI, YOLO, REID, video analysis
-- Secure infrastructure — encryption, key management, threat detection, access control
-- Cloud deployment — AWS, DigitalOcean, Cloudflare, Docker, CI/CD pipelines
✅ Why Companies Work With Me
-- Not theoretical. I've optimized systems handling 1M+ daily API calls. I know what actually works at scale, not what looks good on Medium.
-- Proven results. 30% latency improvement. 99.999% uptime. $500K+ monthly transaction processing. These are measured, real outcomes.
-- Reliability. I build systems that don't break. That means robust error handling, monitoring, and infrastructure that scales.
-- Full ownership. I handle the complete stack—APIs, databases, security, deployment. You don't get half-finished code or missing infrastructure.
✅ Currently Available For
-- SaaS backend development (multi-tenant, billing, RBAC)
-- High-scale API architecture and optimization
-- Real-time application backends (GPS, live tracking, WebSockets)
-- AI/Computer vision/LLM integration into existing systems
-- Performance optimization and scaling existing systems
-- Secure infrastructure and database architecture
If you're building something that needs to actually work at scale—not break when you hit real traffic—let's talk.

Steps for completing your project
After purchasing the project, send requirements so Inam can start the project.
Delivery time starts when Inam receives requirements from you.
Inam works on your project following the steps below.
Revisions may occur after the delivery date.
Architecture & Requirements Review
Review your SaaS requirements, define tenant structure, user roles, data boundaries, and confirm the full feature scope before writing any code.
Database Schema & Tenant Setup
Design PostgreSQL schema with complete tenant isolation strategy. Set up migrations, relationships, and data boundaries that scale safely across unlimited organizations.
