Engineering

My QA work spans software, hardware, APIs, and connected systems. I also build web and iOS products, bringing the same attention to how they work and how people use them.

QA automation & diagnostics

I used prompt-guided AI workflows to migrate UI automation from Sahi to Playwright, reviewing, debugging, and validating generated code before release. I built repeatable Cursor prompts for structured Jira test cases and used Atlassian MCP to identify missing scenarios. My work also includes hardware-validation tools, remote diagnostics, and cross-layer defect investigation.

Playwright · Python · Cursor · Jira · Atlassian MCP

Outcome: Less manual test-authoring effort, more consistent test cases, and expanded functional and regression coverage.

A bilingual iOS app for chart analysis and learning

BaZi Atlas

I built and self-tested the bilingual app and tested its TypeScript calculation engine, including true solar time and chart analysis. I tested Swift/WidgetKit features, Sign in with Apple, purchases, cloud backup, city search, local storage, and deep links.

React Native · Expo · TypeScript · Swift · SQLite · WidgetKit

Outcome: Chart analysis, comparison, learning, and knowledge lookup in one bilingual app.

Reindeer Education

I built responsive program pages, faculty profiles, galleries, and visit booking. The booking flow includes input validation, spam protection, UUID idempotency, and email delivery.

Next.js · React · TypeScript · Tailwind CSS · Resend · Vitest

Outcome: Reusable components and content-driven routing support site updates, with a booking flow that guards against duplicate requests.
