You will get NestJS Backend with Multi Tenant Support & PostgreSQL
Project details
Multi-tenant architecture is hard to get right. Most developers bolt on
"tenant isolation" as an afterthought — and it breaks the moment a client's
data leaks into another tenant's view. I've built it properly.
For Project Preffie (a live B2B2C platform in Australia), I designed the
entire multi-tenant system from scratch using PostgreSQL Row Level Security —
the gold standard for data isolation. Every query is automatically scoped to
the correct tenant at the database level, not the application layer.
What you get:
• True data isolation: PostgreSQL RLS policies ensure zero cross-tenant
data leakage, even if application code has a bug.
• Flexible auth: Email, Google, and Apple login supported out of the box.
• GraphQL or REST: You choose the API style that fits your frontend.
• Built to scale: Redis caching, connection pooling, and async patterns
baked in from day one.
If you're building a SaaS product, agency platform, franchise system, or
any application where multiple businesses share the same infrastructure,
this is the architecture you need — built by someone who's done it in production.

Next.js, NestJS + PostgresSQL Developers Needed for Project
About Nisa
Senior Java Backend Engineer | Spring Boot, Microservices, Kafka
Tangerang, Indonesia - 10:27 am local time
I can help with:
• Java 17/21 and Spring Boot REST APIs
• Microservices and event-driven architecture with Kafka
• Legacy Java/JBoss modernization
• PostgreSQL, JPA and Hibernate query optimization
• Spring Security, JWT, OAuth2 and role-based access control
• Payment, banking and financial workflow integrations
• Production debugging, refactoring and automated testing
• Docker, Kubernetes and AWS deployments
I am most useful when a backend has become slow, difficult to maintain, or risky to change. I can investigate the current architecture, identify the actual bottleneck, propose a practical remediation plan, and implement the agreed changes without unnecessary rewrites.
Recent experience includes financial transaction systems, approval workflows, SaaS platforms, real-time dashboards, and multi-service backend modernization.
My deliverables normally include clean source code, automated tests, API documentation, database migration scripts where required, and a clear handover for your engineering team.
Send me the current issue, architecture, or repository context, and I will outline the first investigation steps before we begin.
