I am Karthik, a software engineer at PhonePe. Most of my day job revolves around building and operating software at scale, collaborating with strong engineers, and turning fuzzy problems into something shippable.

I also spend time on security as a personal interest: reading, experimenting, and thinking about how applications fail in the real world. I am not infallible (no one is), but I try to learn something new whenever I can.

If you came here from a post or a link, thanks for reading. The blog is where I put longer notes; the home page is the short version of who I am.
