Technical QA Specialist focused on manual testing, regression testing, and structured documentation for reliable system performance. I combine software testing discipline with structured research and clear technical/business writing to deliver accurate results across multiple lanes. My background in software engineering allows me to identify issues quickly, document them clearly, and improve system reliability through precise manual and regression testing.

I specialize in four core areas:

My work delivers verified findings and clear recommendations for strategic planning.

3. Technical & Business Writing / Editing
Professional documentation, process guides, and business content written with clarity and precision. I translate technical details into accessible language, edit for consistency and tone, and produce polished deliverables that support decision‑making and compliance. My writing emphasizes structure, readability, and alignment with organizational goals.

4. AI Evaluation & Data Annotation
I specialize in AI evaluation, data annotation, and structured model testing that improves accuracy, consistency, and reliability across LLMs, chatbots, and automated systems. My work focuses on high‑quality human feedback, guideline‑based evaluation, and precise labeling that strengthens model performance.
