UWaterlooMy experience
 logo](/_next/image?url=%2F_next%2Fstatic%2Fmedia%2Fguidept.06afb089.png&w=96&q=75){kind=small}
AI Engineer
Joined the Agentic PM team building a LangGraph multi-agent system that automates expert-network project management as a five-agent pipeline with human-in-the-loop approval gates.
September 2026 – Present logo](/_next/image?url=%2F_next%2Fstatic%2Fmedia%2Frocket.ea34fdbb.png&w=96&q=75){kind=small}
Software Engineer
Led the initial implementation of a C# transaction verification service for the X1/Westcor ecosystem, extending a RED-only check to three-state RED/YELLOW/GREEN suppression logic with LMBRU underwriter notifications. Contributed to the X1 Extended Update integration automating abstract retrieval across 28 states, realizing ~$1M in annual savings, and migrated CI/CD to Argo Rollouts to enable canary deployments.
January 2026 – April 2026
AI Engineer
University of Waterloo IST
Built JADA, an AI-powered job ingestion and recommendation pipeline in collaboration with Microsoft Canada, designing a KNN-based classifier using Cosmos DB Vector Search, and developing full-stack portal services (resume search, profile-based recommendations, InStage integration) supporting 42,500+ users per term.

AI Engineer
Built the RAG document-ingestion pipeline for a low-code LLM application platform, converting heterogeneous documents (PDF, PPTX, Excel) into normalized Markdown, then chunking, embedding, and indexing into a Milvus vector store. Optimized chunking strategy via an evaluation harness, reducing retrieval errors by 30%, and designed an OCR fallback for scanned documents. Curated and labeled training data to fine-tune a Surya OCR model, improving text and table extraction on image-based formats.
September 2024 - December 2024My projects
TermPocket
Made with:
Personal finance for students, built around the school term rather than the calendar month — every report is windowed on real term boundaries, because a co-op term earns and a study term spends down. Record spending by chatting with Pocky, an AI assistant that understands English, Chinese or both: it drafts transactions you confirm with a button (with a ten-minute undo), answers questions about your own spending, and projects savings plans with deterministic math instead of model guesses. Import screenshots — bank lists, receipts, Uber trips, WeChat Pay — read by an OCR model that runs entirely in the browser, and dictate with on-device Whisper, so neither images nor audio leave the device. Tracks six currencies with read-time conversion, savings goals, and a weekly email report; connect your own AI client through a read-only MCP server. Bilingual EN/ZH. 50+ users in production.
SlopFish
Made with:
A fork of Stockfish that plays a chess variant where capturing is mandatory whenever a capture is legal. The rule has to hold at every node, not just the root, so the constraint reaches into move generation, move ordering, check evasions, and the quiescence search — where stand-pat pruning has to be disabled entirely, since a forced capture breaks the lower-bound assumption alpha-beta relies on. Trained a variant-specific NNUE on 17.2M self-play positions, measured it against Stockfish's default network, and shipped the default. A self-play harness whose arbiter enforces the capture rule itself — rather than trusting the engine — surfaced a rule violation in 2.5% of games, traced to promotions being counted as captures; fixed across six call sites, then verified at zero violations in 400 games.
DearByte
Made with:
A self-hosted personal AI agent that combines Apple Watch health data, calendar events, and persistent memory to deliver contextual morning briefs through Telegram. Integrated an open-source HealthKit bridge through remote MCP on Cloudflare Workers, then added daily snapshots, personal baselines, and data-freshness checks. Built a TypeScript agent loop with validated tool calls, model-usage tracking, and enforced spending limits; connects to TermPocket through read-only MCP for spending context. Implemented an x402 purchase flow on Base Sepolia using test USDC, with explicit user approval, seller allowlists, spending caps, and payment receipts enforced in code. Open source · Active development.
AGE Game Engine
Made with:
Architected a C++20 module-based MVC game engine for 2D ASCII games, currently supporting Space Invaders and Snake. Implemented core engine systems including rendering, input handling, game loop management, and collision detection. Designed a flexible Entity-Component System (ECS) for modular game object management, enabling easy extension with new entities and behaviors. Games inherit from a base GameEngine class and implement virtual methods for game-specific logic, streamlining new game development.
AI Sentiment Pulse
Made with:
Led the ML work on a 9-member WAT.ai team building a market sentiment analytics system, fine-tuning DeBERTa-v3 for sentiment and sarcasm detection. Aggregated model outputs with unsupervised statistical methods to produce real-time sentiment signals from social media, and correlated those signals against financial data APIs to surface tradeable trends.
