# Yichen Wu

Legal name: Yichen Wu. Preferred name: Adrien (also written Adrien Wu).

Software Engineer - Production AI Platform at DaoAI Robotics. Home bases in
Vancouver and Toronto; open to AI or full-stack engineering roles in either city.

## Experience

- DaoAI Robotics, Software Engineer - Production AI Platform (May 2025–Present):
  AI Film Platform: built the backend runtime for a Director Agent that turns
  film ideas into editable canvas workflows, with 20 typed tools and server-side
  validation for planning, media generation, and human approval. Decoupled agent
  execution from WebSocket connections using Python asyncio, with Redis Streams
  reconnect replay and PostgreSQL conversation history across API workers.
  Extended Celery/Redis workflows for image, video, and audio generation, adding
  backend status polling and fixing failure-refund gaps and duration-based
  audio billing.
  Video Analytics Platform: implemented the processing logic for 20+ reusable
  nodes and Pydantic workflow validation; built stateful tracking and traffic
  analytics with ByteTrack, OpenCV, NumPy, and SciPy. Removed per-frame Redis serialization from selected
  paths using bounded in-memory state and timestamp guards. In a field deployment,
  the platform supported 48 streams at approximately 5 FPS per stream.
- SageArk, Full-Stack Developer (February 2024–April 2025): deployed the
  company's Next.js site on AWS and built a SageMaker job-recommendation system
  from feature engineering through demo integration.
- Shenzhen Taige Ark Technology, Software Engineering Intern (summer 2019,
  during UIUC): built a Java Android prototype that connected to a smart lock
  over Bluetooth and handled commands between the mobile app and physical lock.

Education: MS Computer Engineering, Northwestern University (2022-2023);
BS Computer Engineering, University of Illinois Urbana-Champaign (2018-2022),
Dean's List. Certifications: AWS Solutions Architect Associate, AWS Cloud
Practitioner.

## Selected personal projects

- Argus: an open-source MCP tool that helps compatible coding agents explore
  user journeys, check state changes, and test edge cases in web apps. It tracks
  tested and unfinished goals and records reproducible bugs with evidence.
  Current release: 0.13.1. Since 0.12.0 it exports standalone Playwright tests
  for reproduced fresh-load text checks; unsupported steps need manual
  completion. Live verification and exported tests apply the same rules, and
  checks that cannot show the symptom (for example, behind a login page) are
  reported as inconclusive rather than fixed. Saved text and HTTP checks can
  also run again without a model. Setup is one command; the first session
  downloads Chromium. Claude Code and Codex plugins provide a guided testing
  workflow.

- AgentDetox: a local Claude Code plugin that helps prevent poisoned writes,
  detect suspicious instruction changes, and clean up selected content with
  previews and backups. Preview version 0.6.0 is published on PyPI and adds an
  optional, off-by-default model check of added text. Its interactive project
  page illustrates prevention, detection, and cleanup; it is not a live agent
  session. Known-risk rules and the model check do not catch every attack.

- Myth Atlas: a live bilingual mythology website built with AI across code,
  content collection, and selected editorial illustrations. Structured entries,
  bilingual search, side-by-side story comparisons, source references, and
  image provenance support the collection. AI-assisted narratives require source review; generated artwork
  is interpretation, not historical evidence.

These are personal projects. The production workflow contributions listed in
Experience belong to Yichen's employment at DaoAI Robotics.

## More engineering work

- Sibyl: a paused research MCP project for persistent evidence, counterevidence,
  and gap tracking, with optional host-authored reports. Two comparative runs
  did not establish a clear benefit over built-in search. Current source is
  host-only; published beta 0.4.0b1 and stable 0.3.0 contain older architectures.

- Scalable Starter: an open-source Next.js and FastAPI foundation with workers,
  Postgres, Redis, and Kubernetes; explores service boundaries and recovery.
  Source: https://github.com/chriswu727/scalable-starter
- Loop: a research release exploring acceptance contracts, agent execution,
  independent verification, versioned Product Sessions, and reviewable delivery
  with replayable receipts. A dated single-model repository evaluation exists;
  its inline execution results do not establish arbitrary-task reliability.
