End-to-End SaaS Engineering
From multi-tenant architecture to subscription billing — SaaS products engineered to grow from MVP to millions of users.
End-to-End SaaS Engineering, done right
Building a SaaS is harder than building an app. You need multi-tenant data isolation, subscription billing with dunning and proration, role-based access control, audit logs, white-labeling, API rate limiting, usage metering, and a 99.9% uptime SLA. We've built 40+ SaaS platforms from scratch — we know the gotchas, the right abstractions, and the boring infrastructure that lets you focus on your product. We can take you from idea to first paying customer in 12 weeks.
Everything you need, nothing you don't.
Multi-tenant architecture
Row-level security (Postgres RLS), schema-per-tenant, or shared-schema — chosen for your scale.
Subscription billing
Stripe Billing, Chargebee, or custom — with proration, dunning, and tax handling.
Role-based access control
Fine-grained permissions, custom roles, SSO/SAML, and SCIM provisioning.
Audit logs
Append-only, cryptographically chained, with retention policies for SOC 2 / HIPAA.
API platform
Versioned REST + GraphQL, rate limiting, API keys, OAuth 2.0, and SDK generation.
Usage metering
Event-based metering for usage-based pricing, with aggregation and invoicing.
White-labeling
Custom domains, themes, branding, and per-tenant feature flags.
Analytics
Product analytics (Amplitude/PostHog), revenue dashboards, and customer health scores.
Compliance ready
SOC 2, HIPAA, GDPR, and CCPA architectures from day one.
From kickoff to launch — in 4 phases.
Discovery
2-hour kickoff + technical audit. We map requirements, constraints, and success metrics.
Design
Wireframes, prototypes, and a design system. We design in code for fast iteration.
Build
Agile sprints with weekly demos. You see working software every week, not slide decks.
Launch
Zero-downtime deploy, monitoring dashboards, runbooks, and a 90-day support window.
