Deliverables

Everything shipped, nothing missing.

Multi-tenant Architecture

Workspaces, org switching, and tenant isolation designed correctly on day one, not bolted on later.

Auth & RBAC

SSO, magic links, MFA, and role-based access down to the resource level, audit-friendly.

Billing & Subscriptions

Stripe subscriptions, seats, trials, proration, invoices, tax, and dunning with real customer portals.

Analytics Dashboards

Product analytics, customer usage, and admin dashboards your team actually opens every morning.

Data & Integrations

Postgres, background jobs, webhooks, and clean APIs your customers can build integrations on.

Scale & Reliability

Caching, queues, observability, and infra ready for your first 10,000 users, not just your first 10.

Architecture

A shape that grows with you.

Web tier, API layer, jobs, and data, cleanly separated so scale problems stay isolated and cheap to fix.

Edge / CDN
Cloudflare or Vercel edge, cached and lightning fast
Web + API
Next.js app + typed API layer with rate limiting
Jobs & Queues
Background workers for emails, exports, webhooks
Data layer
Postgres with row-level isolation + Redis cache
Observability
Sentry, PostHog, structured logs, and health probes
Depth spectrum

MVP to enterprise-ready.

You choose the depth. We wire the same clean architecture either way, so you can upgrade features without rewrites.
