A clear route from zero to independent QA work
Start with evidence and test design, learn delivery across web, API and data, then choose a technical specialization. Each stage ends with work you can explain and defend.
Manual QA modules 1–8: quality, requirements, test design, checklists, test cases and useful defect reports.
You finish with
A reviewed checklist, test cases and a reproducible bug report.
Manual QA modules 9–21 and Development Team modules 1–8: web, API, SQL, tools, refinement, CI, triage and release decisions.
You finish with
A web, API and data investigation plus a reasoned sprint or release decision.
Build automation with AI-assisted engineering, investigate performance, or grow into team and quality leadership.
You finish with
A reproducible capstone with artifacts, trade-offs and a residual-risk decision.
Role labels are learning landmarks, not a job or certification guarantee.
