## About

```text
At QualiFi, I’m building a QA-focused service and portfolio for startups, with practical testing, automation, release confidence, and clear QA documentation. I’m also developing repeatable workflows for critical user journeys and CI-based verification.

As an Independent QA Tester at uTest, I performed manual, functional, and exploratory testing across web and mobile applications. I reported reproducible defects with steps, expected and actual results, and supporting evidence.

For VoiceGuard at the Dev3Pack Global Hackathon, I defined the QA workflow for a voice-first transaction safety assistant. I created scenarios for voice capture and transaction-confirmation flows and coordinated defect tracking with the team.

I’m building a SaaS release-verification system using Playwright, Python, API checks, and CI/CD. My engineering studies at Federal University of Technology, Minna have given me exposure to quality control, process analysis, and failure analysis.
