I ngl miss the thrill of high-performance computing. Or more precise would be where the program's running was directly affected by what I did.
Ever since career took the applications/apps/backend route, i try to optimise but ik it's useless.

The c#/.net would anyway make its own changes, Im not allowed to write direct SQL queries and index-powered joins coz "EF will handle it". Any JS/TS is recreated by Node

Thats how work be but kinda saddening
