How We Scaled to 10 Million Users

Our journey from a small startup to serving millions of users worldwide involved rethinking our entire infrastructure. We migrated to a modern JAMstack architecture, adopted edge computing, and implemented aggressive caching strategies that reduced our TTFB by 80%.

Over the course of eighteen months, we decomposed a monolith into eight domain-oriented services, adopted Postgres connection pooling, and introduced an edge CDN that cut global latency by 62%. None of these decisions were obvious at the time — and several of them turned out to be wrong on the first attempt.

What follows is an honest account of what we did, what failed, what we learned, and what we'd do differently if we were starting again today.
