The Situation & Friction
The Problem
A growing B2B analytics platform was suffering from slow database queries and noisy-neighbor issues as enterprise customer signups increased. Onboarding a new customer required 4 hours of manual engineer setup.
Core Objective
What Needed Solving
Enforcing strict database-level customer isolation, speeding up query response times, and automating self-serve subscription billing.
The Solution
What We Built
A modernized multi-tenant SaaS foundation with automated onboarding, self-serve subscription management, and rock-solid tenant isolation.
Our Engineering Approach
We restructured the database using PostgreSQL Row Level Security (RLS) so tenant data is automatically partitioned at the query layer.
We integrated Stripe customer billing with automatic webhook listeners for trials, upgrades, and invoice generation.
We created an instant self-serve workspace creation flow with custom subdomain routing.
We set up Redis query caching to eliminate redundant database queries.
Concrete Outcomes
Customer onboarding time dropped from 4 hours manual work to under 30 seconds automated
85% reduction in 95th-percentile database query response latencies
Clean architectural baseline ready to scale to thousands of active businesses
