Featured Work

AI Support Operations leads my work in full-stack AI: knowledge retrieval, cited answers, and human review. More projects follow below.

AI Support Operations

Personal project

A multi-tenant support platform that drafts answers from an approved knowledge base, with citations and human escalation.

Workflow

  1. Knowledge base
  2. Retrieval
  3. Cited draft
  4. Human review
  • Implemented document ingestion, embeddings, and RAG retrieval with PostgreSQL/pgvector.
  • Generated response drafts with source citations for human review.
More implementation details
  • Added ticket classification, prioritization, and human escalation.
  • Implemented workspace-scoped access control and team management.

IncidentLens

Full-stack application · Not yet runtime-validated

AI-assisted driving incident review using event logs, timelines, and video evidence.

Workflow illustration, not an application screenshot.

Workflow

  1. Video
  2. AI observations
  3. Evidence
  4. Reviewer approval
  • Integrated Gemini video analysis to generate timestamped observations linked to supporting evidence.
  • Implemented engineer/reviewer roles and approval workflows for AI-generated findings.
More implementation details
  • Integrated private video storage with temporary signed URLs.

Implementation prototype. The application has not yet been run or validated. AI observations require human approval; model accuracy has not been established.
