• Strong grasp of the OWASP Top 10 and of authentication and authorisation flaws such as IDOR, broken access control and session handling.

• Familiarity with spreadsheets as a test record (verdict columns, defect logs, formulas).

Project requirement:

• Writes clear, reproducible defect reports with evidence (screenshots, short clips, request and response captures).
