Capabilities

What I bring

01 · Selected Impact / Selected Cases

Led quality across AI-enabled public-services and insurance products; validated Computer Vision, LiDAR, on-device measurement, and 2D/3D CAD workflows; and held QA across 15+ Big 4 audit applications. Earlier work added security SDK, multi-layer backend, gaming, and blockchain-payment experience — a calm, practical foundation for complex product decisions.

02 · Testing AI-powered products (Computer Vision, LiDAR, object recognition)

I test beyond the happy path: input quality, environmental variation, model confidence, device and sensor limits, degraded conditions, integration behavior, and safe fallbacks. I translate uncertain AI behavior into observable risks, reproducible evidence, and release decisions that product and engineering teams can act on.

03 · Using AI for QA (requirements analysis, test design, risk analysis)

I use AI as an accelerator for requirement review, ambiguity discovery, test-idea generation, coverage comparison, and risk analysis — while keeping human judgment, product context, privacy, and verification in control. The result is faster preparation, sharper questions, and more time for high-value exploratory testing.

Photography lab

Testing ideas beyond the screen.

Photography is more than a creative outlet — it is another laboratory for quality thinking. Every frame demands attention to composition, light balance, sharpness, and color accuracy, the same qualities I evaluate in visual and UX QA. Whether I am planning a shoot, refining a workflow, or choosing the right tool for the job, the discipline is the same: understand the goal, control the variables, and deliver a result that holds up under scrutiny.

Step into the gallery to see how that same disciplined attention to detail looks through a lens — and imagine what it can do for the quality of your product.
