The most valuable bugs are the ones your customers never see. Over the past 12+ years, I have logged more than 26,000 hours worth of QA work across 70+ projects. Several client relationships span multiple years and thousands of hours, reflecting the level of trust, consistency, and ownership I bring to every project. I am a Senior Manual QA specializing in GitHub-based development workflows, pull request validation, exploratory testing, and AI-assisted development environments. My role is not simply to find bugs. My goal is to help teams ship with confidence by identifying issues before they reach production, where they become significantly more expensive and disruptive to fix. I specialize in Manual QA for iOS, Android, and Web applications, helping product teams reduce release risk through exploratory testing, regression testing, feature validation, and detailed bug investigation. By uncovering issues early in the development cycle, I help teams avoid costly production incidents, customer-facing defects, and unnecessary rework. Throughout my career, I have worked closely with founders, product managers, designers, developers, and distributed teams to improve product quality and support reliable releases. I enjoy understanding how a product works, exploring user behavior, identifying edge cases, and providing actionable feedback that helps teams make informed decisions before shipping. In addition to traditional QA activities, I regularly work within GitHub-based development workflows, validating pull requests, reproducing reported issues, verifying fixes, reviewing implementation outcomes, and providing structured feedback before changes are merged or released. As development teams increasingly adopt AI-assisted coding tools, QA plays an even more important role as the final validation layer. Recent projects have expanded my responsibilities beyond traditional testing into PR validation, agent-assisted development workflows, QA session orchestration, and structured feedback loops between developers, coding agents, and product teams. Areas of expertise: • Manual Testing (iOS, Android, Web) • Exploratory Testing • Regression Testing • Feature Validation • Release Validation • Pull Request Validation • GitHub-Based Development Workflows • Cross-Device Testing • Bug Investigation & Reproduction • QA Documentation & Reporting • AI-Assisted Development Validation • Agile Product Development Tools and Platforms: • GitHub • Jira / Atlassian • Confluence • Azure DevOps • Charles Proxy • Trello • TestRail • Mixpanel • Loom • Lightshot Device Lab Available for Real-Device Testing: iOS Devices • iPhone 6 Plus (iOS 12) • iPhone 7 Plus (iOS 13) • iPhone 12 Pro Max • iPhone 13 Mini • iPhone 14 Pro Max • iPhone 15 Pro • iPhone 16e • iPod Touch 6th Generation Android Devices • Samsung S7 • Samsung S9 • Samsung Note 9 • Samsung A51 • Samsung A56 Desktop • MacBook Pro 15" • iMac M1 I am particularly interested in long-term collaborations where I can develop a deep understanding of the product, contribute meaningful QA insights, reduce release risk, and become a trusted quality partner for the team rather than simply an external tester.
