Databases, systems, backend

Final-year undergraduate at IIT Roorkee. I build low-level systems with a database instinct: storage engines, indexers, and the backend services around them, mostly in Rust. What holds my attention is the layer underneath: how systems behave when things go wrong, and how the software everyone depends on actually works inside.
