I am Nguyễn Thái Hảo, also known as KanzuWakazaki. I design and ship software from system boundaries and data flow through implementation, verification, and production delivery.
AI-assisted systems — orchestration, guardrails, validation, fallback, and reviewable outcomes.
Backend platforms — APIs, service boundaries, reliability, security, and operational visibility.
Product engineering — accessible interfaces, measurable workflows, focused testing, and maintainable delivery.

Refreshed daily from the GitHub GraphQL API. Private activity appears only as GitHub's aggregate contribution count; private repository names and details are never requested or rendered.
Clear boundaries before complexity. Validate AI output, design explicit fallback, test observable behavior, apply least privilege, and keep delivery reproducible.
Automation
profile-metrics.ymldiscovers public repositories, accepts optional preferences throughPROFILE_FEATURED_REPOSITORIES, generates responsive SVG snapshots, and commits only changed output with the scopedGITHUB_TOKEN.contribution-snake.ymlpublishes light and dark contribution animations to theoutputbranch.profile-quality.ymltests selection logic and validates live generated output, README references, XML, and accessibility metadata.- GitHub Actions are pinned to immutable commit SHAs and updated through Dependabot.
