Capabilities

What I can contribute to a technical team.

My strongest work sits between implementation and verification: building clear interfaces, testing real behavior, documenting problems, and improving the result.

01

Front-end implementation

I can translate a defined product or content requirement into a responsive, maintainable interface.

  • Semantic HTML, CSS, and JavaScript
  • Responsive layouts and mobile behavior
  • Reusable page and component patterns
  • Accessibility basics and technical SEO
02

Web QA and issue documentation

I can review a site systematically, reproduce defects, and communicate what needs to change.

  • Navigation, forms, and interaction testing
  • Cross-device and breakpoint checks
  • Content and state consistency review
  • Clear reproduction steps and verification notes
03

AI evaluation and data quality

I have contract experience reviewing multimodal output against detailed project standards.

  • Text, image, audio, and video evaluation
  • Timestamped caption-track review
  • Instruction-following and quality assessment
  • Structured rationales and correction workflows
04

Digital product prototyping

I can turn a focused idea into a working first version that exposes the real product questions.

  • Core user-flow definition
  • Interface and information architecture
  • Simple state and data behavior
  • Testing, limits, and next-step documentation

Process

I work from clear requirements to verified output.

  1. 1

    Define

    Clarify the user, requirement, expected behavior, constraints, and completion criteria.

  2. 2

    Build

    Implement the smallest useful version before adding secondary features.

  3. 3

    Verify

    Test the main path, edge cases, responsive behavior, and failure states.

  4. 4

    Document

    Record issues, decisions, limits, and the evidence used to confirm the result.

Target roles

I am focused on work with technical growth.

My target roles include front-end or web development, web QA or QA analysis, AI evaluation and data quality, and technical product internships or contracts.

My strongest fit is work where I can build, test, investigate, document, and steadily take ownership of more complex systems.
