SaaS Unicorn

Scaling to 10M Users without Melting Down

How we re-architected a monolithic Node.js app into scalable microservices.

SaaS Unicorn
99.99% Uptime during 5x traffic spike
75% reduction in latency
45min to 4min deploy time
"We were spending $13K a month on AWS. LeanOps cut our cloud costs by 80%, improved performance, and reduced onboarding from days to hours."

The Challenge

Infrastructure complexity often becomes a bottleneck for fast-moving teams. SaaS Unicorn faced significant hurdles in maintaining reliability while scaling their user base from initial thousands to over 10 million active users.

Our Approach

We implemented a robust multi-phase optimization strategy, focusing on high-impact areas that directly improved performance and significantly reduced monthly cloud spend.
