About me
I conduct SaaS QA audits — full-cycle functional testing, security checks, and integration testing across complex web platforms.
Every bug comes with reproduction steps, severity classification, and screenshot evidence. Deliverables include Excel trackers, OWASP security findings, Lighthouse performance baselines, and PDF reports your dev team can act on immediately.
I test auth flows, payments, OAuth, APIs, UI/UX, and performance. No vague reports — just clean, thorough QA that reflects the real state of your product.
