Every claim below links to something you can click, fork, or load-test.
The risky 20% of every MVP — tenant isolation, entitlements, usage billing — done right.
Most SaaS MVPs defer multi-tenancy, RBAC, and billing. When they bolt it on later, every migration is a rewrite.
Next.js 16 App Router RSC + Server Actions; Postgres row-level security per tenant; role→permission→entitlement RBAC layer; Stripe metered subscriptions with webhook-driven state machine.
Rendering 10k events/sec without freezing the UI.
Real-time dashboards that handle high event throughput without main-thread jank or memory leaks under sustained load.
WebSocket ingestion into a Web Worker ring buffer; canvas rendering with dirty-rect redraw + requestAnimationFrame backpressure; SSE fallback path.
No black boxes. This is what you can hold us to from week one.
You talk to the people writing the code. No account managers, no relayed questions, no junior swap after signature.
Every week: a working staging build, a recorded walkthrough, and an updated sprint board you can open any hour of any day.
Sprints end with website on a live URL — not status decks. If a milestone slips, you hear it before the demo, not during it.
Code lands in your GitHub organization from the first commit. IP transfer at launch is a formality, because it was always yours.
After launch we stay on: same engineers, priority queue, fixes for anything our code broke — included, not upsold.
