I'm Harshal Sawant, a backend and systems engineer based in Mumbai, India. I got into programming the hard way - through Android rooting, kernel modules, and digging into Linux internals - and never really stopped going deeper.
Today I build low-latency backend services, distributed systems, and developer tooling, mostly in Rust and Go. I care about things that most people abstract away: scheduler behavior, memory pressure, syscall overhead, and what actually happens under the hood when your system is under load.
