When a major platform ships a broken update, the damage rarely arrives with a clear warning. A core metric drifts imperceptibly, a graph tilts a few degrees, and engineers argue over whether the signal is real. Bhasker Goel, a software engineer at Google Ads in Bengaluru, works on the narrow but consequential gap between a system beginning to fail and a monitoring system recognising that failure.
Goel, an alumnus of IIT Guwahati, built financial infrastructure at DE Shaw before joining Google, where he now designs reliability systems for Google Ads. In environments of this size, small anomalies can cascade rapidly. The regressions his systems are built to catch tend to be gradual and silent; left undetected, they can become expensive quickly.
