Proof | Renat Usmanov
Artifacts that prove this is product building, not just screens. In 20 seconds you see: works like a mini-team.
Who this page is for
Founders / PMs
To understand how I reduce "solo risk" and ship predictable sprints.
CTO / Tech leads
To see the artifacts devs actually use: states, edge cases, rules.
QA / Analysts
To get acceptance criteria, negative/edge scenarios and clear Definition of Done.
Hiring managers
To verify this is product work (flows + systems + build), not just UI screens.
When you get it
Week 1 (state map) → Week 3 (QA pack) → every sprint (component specs).
Artifacts
State map
Statuses, transitions, errors, permissions and latency. This is what prevents surprises in dev/QA.
- Statuses: Draft → Review → Approved → Applied
- Transitions and RBAC rules
- Errors: validation, conflicts, retries
- Audit logs: who changed what
Acceptance Criteria pack
Happy/negative/edge scenarios, logging rules and what is considered an error.
- Happy path + alternatives
- Negative cases and error rules
- Edge cases: duplicates, timeouts, races
- Definition of Done for QA
These are real artifacts from projects
Minimal content (1–2 pages), but real format: headers, tables, states, edge cases. This significantly reduces competition and shows work is done like in a team.
