The Challenge
Acme Corp had found product-market fit with their SMB offering, but their “single database” architecture was blocking them from moving upmarket. Enterprise clients were demanding data isolation, SSO (Single Sign-On), and strict SLAs that their current Node.js monolith couldn’t guarantee.
They were losing deals because their tech stack couldn’t check the boxes for enterprise compliance.
The Solution
We performed a strategic “Enterprise Readiness” refactor.
Multi-Tenant Architecture
We migrated their database schema to a row-level security model (RLS) using PostgreSQL, ensuring that data leakage between tenants was mathematically impossible. For their largest clients, we built a pipeline to spin up isolated “pod” environments.
Enterprise Security Suite
We implemented SAML/SSO integration (Okta, Azure AD) so enterprise IT admins could manage access. We also added detailed audit logs and role-based access control (RBAC) throughout the application.
Performance Optimization
We introduced a tiered caching strategy using Redis and CDN edge caching, reducing API latency by 60% globally.
Key Technologies
- PostgreSQL RLS: For secure multi-tenancy.
- Auth0: For managing complex enterprise identity requirements.
- AWS Lambda: For scalable background job processing.
- Terraform: For automating the deployment of isolated tenant pods.
The Results
With the new architecture, Acme Corp successfully closed their Series B funding.
- $10M in New ARR: Directly attributed to closing Enterprise contracts that were previously blocked.
- SOC2 Compliance: The new infrastructure passed security audits with flying colors.
- 99.99% SLA: They can now contractually guarantee uptime to their biggest customers.
