Verified competencies

• Backend fundamentals

  A minimum of 70% in the baseline assessment. Twenty-five questions drawn from a larger bank, 45 minutes, three attempts.

• Task: an API that survives bad input

  A running HTTP service with at least three endpoints. It must reject malformed input with 400 and a message naming the field, never with a 500, and it must return the same result when the same create request arrives twice.

• Task: a data model and the queries on it

  A schema with at least three related tables, a seed of ten thousand rows, and a list endpoint that stays under 200 ms on that data. The README shows the query plan before and after the index you added.

• Final project

  A deployed service with a repository, a public URL and a README. Authentication, one write path that is safe to retry, and error responses a caller can act on.

• Community contribution

  Five substantive contributions to other members: code reviews, feedback on their work, or answers to their questions.

• Documentation

  A README covering the data model, the endpoints with their status codes, how to run it locally, and which decisions you would revisit at ten times the traffic.

• Professional practice

  Three merged pull requests in the repository you connect, each describing what changed and why.
