SaaS product development

Multi-tenant productsbuilt to onboard the hundredth customer

Architecture, product surface, and deployment pipeline for SaaS: the shape of work behind Verse AI, a tenant-isolated AI platform running on a seven-layer AWS stack.

Full system architecture — Next.js frontend, NestJS backend with an LLM gateway, and a Postgres + Qdrant + Redis data layer routing across five LLM providers

What we build

The work itself,component by component

Everything listed here is something we have built into a production system, not a capability we are willing to attempt.

Multi-tenant architecture

Isolation in the schema, so a tenant boundary is a database constraint rather than a code convention.

Onboarding and provisioning

A new tenant is automated end to end, including seed data and first-run state.

Billing and plans

Subscription states, usage metering, and upgrade paths as first-class logic.

Admin and support tooling

The internal console your team needs to actually support customers.

Usage analytics

Per-tenant activity so churn risk is visible before renewal.

Deployment pipeline

CI, migrations, and rollbacks that make weekly releases unremarkable.

Why it matters

What changesonce it is running

Three things a buyer of this work should be able to hold us to.

RAG pipeline — ingestion (extraction, chunking, TF-IDF and dense embedding into Qdrant) and retrieval (hybrid cosine + BM25 search, RRF, reranking) feeding the LLM orchestrator

Onboarding without engineers: Provisioning is automated, so growth does not consume the build team.

Isolation you can prove: Tenant scoping at the storage layer is demonstrable, which matters in security review.

Supportable: Internal tooling ships with the product rather than a year after it.

Stack we use for this

  • Next.js
  • TypeScript
  • FastAPI
  • PostgreSQL
  • Redis
  • Stripe
  • AWS
  • Docker

How it runs

Four stages,and you can leave after any of them

Scope

We agree what the system does and what shipping means, in writing.

Build

Short cycles in your repository, running before it is finished.

Ship

Deployed into your cloud account, reachable by a real user.

Stay

Maintenance and roadmap by the same engineers who built it.

FAQ

Questionswe get asked

Single-tenant or multi-tenant?

Multi-tenant by default; single-tenant where a customer's compliance regime demands it. We model both costs.

Can you take over an existing SaaS?

Yes, beginning with an audit so the estimate reflects the real codebase.

How do you handle enterprise security review?

Isolation, access control, and audit logging are designed to be demonstrated, not described.
