Hi, I'm Ines Panker.
I'm a senior staff engineer at Sleuth, a SaaS observability platform (the first engineer they hired, de-facto architect), and the person who just gave this talk.
Almost two decades of building software.
Multi-tenant architecture. Circuit breakers guarding 2-3 million third-party API calls a day across about 40 external APIs. Real-time anomaly detection for hundreds of clients.

How Many Tests Is Enough?
What makes us really calm when deploying code to production? A green test suite with 100% test coverage. But then we merge, deploy, go to lunch… and somewhere out there a user does something so creative that production goes down anyway. There’s no amount of tests that makes the bugs go away. We wish test coverage was a magic number, just like we want to believe in the power of other metrics (LOC, story points, DORA, …). This talk grapples with two questions: what our tests actually catch, and why we keep reaching for these numbers.

None yet, I haven't written this one up. Accept me at your conference and I'll finally have the time to build it.
