How I work

Depth where it matters

A few capabilities, each backed by real, linkable work — not buzzwords.

AI-assisted workflows (human-in-the-loop)

I design tools that orchestrate AI without surrendering control or privacy. My Work Log Builder assembles structured daily logs from Jira, Slack, Google and GitHub using a manual external-AI step — deliberately never calling an AI API itself, so no data leaks to a model provider.

  • Human-in-the-loop
  • Privacy-preserving
  • Tool orchestration
Workspace (Work Log Builder)

On-device intelligence

I ship ML features that run entirely on the device. Aegis Wallet uses on-device OCR to extract card details from camera scans with zero network calls.

  • On-device
  • OCR
  • No cloud

LLM application engineering

Actively building toward production LLM apps — prompt design, tool use, and retrieval. Marked as a learning direction, not a shipped claim.
