I am a Software QA Engineer with 5.5+ years of experience delivering quality across enterprise SaaS, AI-powered products, CRM integrations, and Blockchain/Web3 platforms.
I have owned end-to-end QA activities, including test planning, feature validation, release readiness, production verification, and regression testing. I am comfortable working as a sole QA supporting multiple developers and coordinating a high volume of QA deliverables each sprint.
I have built automation frameworks from scratch using Playwright, TypeScript, and Cucumber, and I have also worked with Cypress, Selenium, Postman, and JMeter. My work has helped improve regression coverage and reduce manual testing effort significantly.
I have experience validating APIs, SQL data, integrations, and complex business workflows across AI recruitment platforms, enterprise SaaS products, restaurant management systems, and blockchain applications. I also collaborate closely with Product Managers, Business Analysts, Developers, and Data/AI teams to improve release quality.
I have led QA efforts across multiple concurrent projects and mentored junior team members, helping improve testing consistency, onboarding, and QA processes. I take pride in being proactive, detail-oriented, and accountable for product quality.
I am based in Ha Noi, Vietnam, and I speak English with professional working proficiency. I hold an Advanced Diploma in Software Engineering and an ISTQB Foundation Level certification, and I have been recognized as Employee of the Year for my contributions to QA excellence.
