Full-Stack SaaS Development — From Architecture to Launch

Building a SaaS product means solving problems that go beyond basic web development: multi-tenancy, subscription billing, role-based access, usage limits, and a backend that can scale with your customer base. Solviba has shipped production SaaS platforms in the medical, fintech, and productivity spaces — and we understand what it takes to get from idea to a product users actually pay for.

Multi-Tenant Architecture & User Management

We design your SaaS from the ground up with multi-tenancy in mind. Each customer's data is properly isolated, user authentication is handled securely via Supabase Auth or custom JWT flows, and role-based access control (RBAC) is built into the data layer — not bolted on after the fact.

• Tenant isolation at the database and API level

• Role-based permissions for admins, members, and viewers

• Invite flows, team management, and account settings

• Audit logging for compliance-sensitive use cases

Subscription Billing & Payment Integration

We integrate Paddle or Stripe to handle subscription plans, free trials, upgrades, downgrades, and webhook-based status synchronization with your backend. Billing is one of the most failure-prone parts of a SaaS — we build it to be robust and testable from day one.

Scalable Frontend Built for Product-Led Growth

Your SaaS UI needs to onboard users quickly, surface value immediately, and stay out of the way. We build React interfaces with TypeScript, Tailwind CSS, and ShadCN that are fast to load, easy to navigate, and designed around your activation metrics — not just aesthetics.

Infrastructure, Deployment & Post-Launch Support

We deploy your SaaS to Vercel or Railway, configure environment variables, set up monitoring, and establish a deployment workflow you can operate independently. We stay involved after launch to help you ship new features and respond to user feedback without breaking what's already working.
