When your app serves millions of users across 48 countries, quality issues are inevitable — but detecting them is the real challenge. Bug reports are vague, user feedback is shallow, and no amount of lab testing can simulate real-world chaos. Arsenyi Batyrov will share how his team tackled these problems by rolling out a dogfooding program in a global ride-hailing company. You’ll hear how they scaled from a small pilot to 1000 active participants, automated bug triage without a single programmer, and turned internal feedback into real product improvements. More than just a success story, this is a candid look at what worked, what failed, and why dogfooding isn’t a silver bullet — but can be a game-changer when done right.
