AI/LLM Engineer focused on production GenAI systems, RAG evaluation, AWS Bedrock delivery, and agent tooling.
Most recent work is private or organization-owned. This profile highlights stack, delivery scope, and public artifacts rather than treating public repos as the full portfolio.
- Languages: Python, JavaScript/TypeScript, SQL, Bash
- AI / LLM: AWS Bedrock, RAG, evaluation datasets, guardrails, red-team workflows
- AWS / Serverless: Lambda, DynamoDB, Amazon Connect, Lex, IAM, SSM, CloudWatch
- Backend / Apps: FastAPI, SQLite, REST APIs, admin tooling
- Observability / Ops: Datadog APM, CloudWatch, tracing, token/RAG metrics, canary checks, readiness checks
- Automation / QA: Playwright, pytest, GitHub Actions, structured logging, security checks
- Production GenAI systems — Bedrock-backed workflows, serverless APIs, contact-center automation, observability, and runbooks
- RAG & evaluation delivery — golden datasets, token/retrieval metrics, latency checks, retry automation, and admin tooling
- Agent and red-team tooling — browser automation, evidence capture, judge-analysis workflows, reliability harnesses, and safety tests
Designed and shipped Korean-language AI operations systems using Amazon Connect, Lex, Bedrock, Lambda, DynamoDB, and Google Workspace automation. The work included observability and operator runbooks.
Built golden-dataset flows, evaluation guidebooks, latency scripts, retry automation, admin interfaces, and delivery packaging for retrieval systems.
Built test harnesses, browser automation, evidence capture, judge-analysis workflows, readiness checks, and infrastructure hardening for LLM systems.
Built Datadog/APM instrumentation, tracing guides, token/RAG metrics, canary checks, readiness checks, CloudWatch handoff docs, and incident reports.
Public repositories are representative samples. Most production delivery happens in private and organization repositories.
- paper-banana-bedrock — AWS Bedrock port of PaperBanana for Korean prompt-generation workflows
- paperclip-dev-factory — AI-assisted development factory with verification gates
- paperclip-orchestration — orchestration server for approvals and agent state
