SaaS & Cloud Platforms

Building a SaaS product is a different problem than building an app — the technical decisions that matter are the ones invisible to users: how tenant data is isolated, how a free-to-paid upgrade actually gets enforced server-side (not just hidden behind a paywall screen), and how the system behaves when usage spikes 10x overnight.

We've implemented freemium subscription models in production — Lyfted's premium tier (deep sentiment analysis, advanced progress visualizations) is gated through RevenueCat with native Apple and Google in-app purchase handling, which means entitlement checks happen server-side and can't be bypassed by a modified client. That's the kind of detail that's easy to get wrong on a first SaaS build and expensive to fix once real subscribers exist.

Multi-tenant architecture is planned upfront, not retrofitted: whether tenant data is isolated by schema, by row-level security policies, or by fully separate databases depends on the compliance requirements and scale you're targeting, and we make that call explicitly rather than defaulting to whatever's fastest to prototype.

Cloud infrastructure choices follow the same logic — Supabase and Firebase get you to production fast with solid defaults for auth, real-time sync, and storage; a custom Node.js and PostgreSQL backend gives you more control when the product's data model or compliance needs outgrow what a managed platform offers. We'll tell you honestly which one fits your stage, rather than selling the more expensive option by default.

For an existing product moving from single-tenant to multi-tenant, or migrating off a monolithic backend, we scope the transition so it doesn't require downtime or a risky big-bang cutover for customers already depending on the system.
