Design a Versioning Strategy for a Public REST API

Behind every app a user touches, there's a quieter system doing the actual work — routing requests, holding state, refusing bad input politely. Backend engineers build and care for that hidden layer. The role is part craft, part diplomacy: you're designing APIs that other engineers will lean on for years, and a careless schema choice can echo through a company for a long time. Good work here looks like code that's boring in the best way — predictable under load, easy for the next person to read, observable when something breaks. Students grow into this role by getting comfortable with Python or another server language, then learning how databases really behave when traffic spikes.
