Currently based in Vietnam (UTC/GMT +7) and collaborating with international teams across time zones. I help companies bring clarity and structure to digital products — whether processes are already defined or still evolving. With 15+ years in software delivery (QA Engineer → Business Analyst → Product Owner), I understand the full product lifecycle: from discovery and requirement definition to validation and release. I have worked on: • Customer-facing web portals and mobile applications • Cloud platforms and SaaS ecosystems • 3D CAD software • Medical device systems in regulated environments • AI-powered micro-SaaS and e-commerce products (as founder) In addition to corporate environments, I work my own projects using modern no-code / “vibe coding” approaches. This hands-on experience allows me to think not only as an analyst, but as a product creator who understands speed, iteration, and real user feedback. I can support you with: ✔ Business & System Requirements (BRD / PRD / User Stories) ✔ Process design (As-Is / To-Be) — including building structure from scratch ✔ Backlog creation and prioritization ✔ Stakeholder interviews and alignment ✔ Acceptance criteria definition ✔ UAT planning and coordination ✔ Manual QA, test case design, and validation support ✔ Risk and edge-case identification before release Because I started in Software Quality Assurance, I approach analysis with a quality mindset. I look for gaps, edge cases, and misalignment early — reducing rework and delivery friction later. Whether your team needs clearer documentation, stronger delivery discipline, or better alignment between business and development — I help turn ambiguity into structured execution.
