SaaS Development
We design and build scalable SaaS platforms end-to-end — from MVP validation to enterprise-grade systems. Multi-tenant architecture, subscription billing and cloud infrastructure engineered to grow with your business.
What we deliver
Multi-tenant architecture
Shared-schema multi-tenancy with Postgres row-level security and a tenant_id propagated from the JWT on every query. We choose shared-schema over schema-per-tenant so migrations do not multiply per customer, and put PgBouncer in transaction mode in front of the pool so connection count survives real load.
Subscription billing
Stripe Billing wired end to end — plans, trials, proration, metered usage and dunning — with webhooks as the source of truth reconciled idempotently against your own entitlements table. We never trust the client for plan state; the webhook decides what a tenant can do.
Operator dashboards
Data-dense admin panels like our VESPER and PULSE dashboards: server-paginated tables, saved filters, bulk actions and role-scoped views. Heavy aggregations run as server components against read paths so the UI stays responsive without shipping the whole dataset to the browser.
Auth & RBAC
Session or JWT auth with OAuth, magic links and per-tenant role-based access enforced on the server, not just hidden in the UI. Permissions live in one policy layer, so a new role is a config change rather than a scavenger hunt across routes.
APIs & integrations
Typed contracts with tRPC or OpenAPI so the client and server cannot drift, plus signed webhooks and background jobs for third-party sync. Idempotency keys and retry-with-backoff make integrations survive the flaky reality of other people’s APIs.
Analytics & reporting
In-product event tracking, funnels and exportable reports on a warehouse-friendly event schema. We instrument the activation and retention moments up front, so product decisions run on data instead of vibes.
How we work
- 01
Discovery
We map users, jobs-to-be-done and the billing model, then cut scope to an MVP that proves the core loop. You leave with a fixed feature list, a data-model sketch and a timeline you can hold us to.
- 02
Architecture
We design the tenant model, auth boundaries and infra before feature code — versioned reversible migrations, typed API contracts and an ADR for every decision that is expensive to undo. Load-shaping choices (indexes, pagination, caching) are made now, not after the first outage.
- 03
Build
Iterative sprints against a live staging URL, feature-flagged so half-done work ships dark. Every PR runs typecheck, lint and tests in CI, and we load-test hot paths with k6 against P95 targets before they reach production.
- 04
Launch & scale
We deploy behind structured logging, tracing and alerts, with error budgets that tell us when to slow down. After launch we watch the funnel and the latency graphs and turn that into the next roadmap.

Frequently asked
How long does a SaaS MVP take?
Most MVPs reach a live, billable product in 8 to 12 weeks. We fix the feature list in discovery so the timeline is a commitment, not a guess, and ship weekly to a staging URL so there are no surprises at the end.
Do we own the code and IP?
Completely. Everything lives in your Git organization from day one and you keep full IP — no proprietary runtime, no per-seat platform fee, nothing that holds your product hostage if you take it in-house.
How do you keep it maintainable after handover?
We ship ADRs, a runbook and tests so the bus factor is not one person’s memory. Typed contracts and CI gates let a new engineer change code safely, and we can stay on a support retainer if you want continuity.
Will it actually scale, or just demo well?
The multi-tenant model, connection pooling and indexed read paths are load-tested against P95 targets before launch, not bolted on after. When you outgrow a single instance the architecture is ready for read replicas and horizontal scaling.
