TL;DR

Wolrix has shipped a multi-tenant SaaS-shaped operations platform — row-level security, 5 user roles, 1,000+ daily ops, Stripe per-tenant, Clerk org management, subdomain isolation — in 6 weeks. We've also done $12K / 2-week SaaS launches that hit paying users by week 3 (AI candidate screening tool, anonymized). Top Rated Plus on Upwork, 100% Job Success Score, 42 projects, $200K+ earned, 5 production platforms shipped, 4 industries with shipped proofs. We work in SaaS on the same model: one technical lead, fixed price, 2-8 weeks, NDA before any details. Tenant isolation is row-level, not advisory. Stripe is per-tenant, not "one Stripe account, oh well." AI retrofits drop into your existing stack with eval harness and per-tenant cost telemetry; we don't rip and replace.

Multi-tenant operations platform

A multi-tenant operations platform with row-level security, 5 user roles, 1,000+ daily ops, Stripe per-tenant, and subdomain isolation. The MSP platform productized as multi-tenant SaaS.

  • Row-level security in Postgres + tenant-scoped Drizzle queries
  • Stripe Customer per tenant — billing isolation by default
  • Subdomain isolation via Vercel wildcard
  • Clerk org management with role hierarchy
  • 1,000+ daily ops across 5 user roles
Patterns we'll build for you

What we'd build in SaaS

Concrete patterns named with stack components. AI as a feature, not a gimmick.

Multi-tenant SaaS from zero

Next.js + Postgres RLS + Drizzle + Stripe per-tenant + Clerk orgs + Vercel wildcard subdomains. Day 1 ship; Day 14 paying users on the lean version.

AI retrofit on existing SaaS

Drop Claude or GPT into one feature inside your existing app. Eval harness, cost telemetry per tenant, prompt versioning. We don't rip and replace your stack.

Per-tenant AI cost controls

Token budgets per tenant, hard caps with alerting, per-feature cost reporting in the operator console. Stops surprise OpenAI bills before they hit your margin.

Cross-tenant view: users, MRR, churn, support flags. SQL-backed. Impersonate-as-user with audit log so support can debug without a screen-share.

How we handle SaaS-specific concerns

Tenant isolation via row-level security in Postgres plus tenant-scoped Drizzle queries — a hard boundary, not a WHERE clause anyone can forget. One Stripe Customer per tenant so billing stays isolated. Subdomains via Vercel wildcard. Auth via NextAuth or Clerk with org switching, role hierarchy, and SSO-ready on day one.

For AI features, per-tenant token budgets and hard caps. Cost telemetry rolled up in the operator console so a noisy customer can't blow your OpenAI bill. Eval harness on every prompt change so you don't ship regressions.

Default stack

Boring tools, sharp choices.

Same stack across every engagement. Plus Clerk for SSO/MFA on enterprise plans.
