Building debugging infrastructure is a powerful way to level up your team and career. Here are the core points from the lesson:
Invest in infrastructure like logging, dashboards, session recordings, bisect tools, and experiment tracking to make debugging easier for everyone
Plan ahead by adding useful logging into products before bugs occur to speed up investigations and root cause analysis
Funnel logging is especially valuable because it formalizes the end-to-end data flow, making it easier to spot where issues happen
Building internal tools, even simple ones like the Log Insight tool at Meta, can lead to major team-wide adoption and career milestones
Internal tooling projects are great side projects because they serve engineers directly, have less red tape, and can be very high impact
