2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

  2. Platform APIs intermediate

    A platform exposes APIs to internal teams. How should these differ from APIs exposed to external customers?

  3. Platform APIs intermediate Multiple choice

    Product teams need a Kafka topic and an object-storage bucket per service with quotas and retention that change over time. Should the platform expose a synchronous provisioning call that returns when the resource exists or a declarative resource reconciled by a controller or a pull request into a shared Terraform repository?

  4. Platform APIs intermediate

    The Hugging Face Hub stored large model and dataset files with Git LFS which versions whole files - appending 1 MB to a 5 GB file re-uploads 5 GB. In 2025 the Hub began moving repositories onto Xet storage which splits content into roughly 64 KB content-defined chunks aggregated into roughly 64 MB blocks so only changed chunks travel. The API developers call did not change. What forced the change and what had to stay stable and where would copying it be a mistake?
