Projects
My Little Pony
View Project- Independently developed a 2D multiplayer extraction shooter (Tarkov-style) set in the Fallout Equestria universe, built with Unreal Engine 5 (PaperZD), featuring a complete frontend and backend system.
- Built in-game UI (PipBuck interface) using React + TypeScript, implementing five core pages — Lobby, Storage/Inventory, Market, Map, and Character Status — with real-time room state and chat sync via WebSocket.
- Implemented in-game HUD system including HP bar, mana bar, XP bar, weapon ammo display, weapon hotkey preview, weapon selection wheel, and post-match settlement screen.
- Built backend service with Hono + TypeScript (Bun runtime); PostgreSQL (Drizzle ORM) and InfluxDB for data; Zod for request validation.
- Implemented account authentication system with user registration/login and JWT middleware; built player inventory and stash persistence (JSONB in PostgreSQL).
- Developed lobby room management system with join room, ready/start game, room state broadcast and real-time chat via WebSocket; backend auto-spawns UE5 dedicated server process.
- Built player-to-player matching market with order book model, price-priority matching logic, liquidity bot, and multi-timeframe candlestick price history in InfluxDB.
- Implemented post-match settlement system including loot distribution, kill tracking, and XP persistence, with results pushed to clients via WebSocket.
- Handled UE5 game logic: PaperZD 2D character, melee/ranged/hitscan weapon systems, multiple turret AIs, item and loot drop tables, container/door/terminal interactions, fog-of-war component, and multiplayer network sync with WebSocket-backend integration.
QQ Chat Agent
- Independently developed a Node.js-based QQ bot bridge service, connecting to QQ via NapCat (OneBot v11), with a subprocess-driven Letta CLI (stream-json mode) to deliver an AI roleplay bot with long-term memory and tool-calling capabilities.
- WebSocket connection to NapCat; parsed OneBot v11 message events and filtered responses by three conditions: private chat, @mention, and admin commands.
- Launched Letta CLI as a subprocess; implemented bidirectional streaming JSON communication via stdin/stdout pipes with a custom streaming JSON extractor for handling incomplete chunk concatenation.
- Cached image URLs keyed by message_id (LRU, max 500 entries); injected images as image/url into Letta multimodal message content on quoted replies.
- Differentiated cache_write / cache_hit / prompt / output token types; computed costs in real-time using Claude pricing and wrote results to local credit.txt and log.txt.
- Implemented !clear command via Letta REST API PATCH /v1/agents/:id/reset-messages to reset conversation; split long replies into 1800-character segments prioritizing line breaks.
Cryptocurrency Trading Platform
View Project- Independently developed a BTC/USDT simulated cryptocurrency exchange platform with a complete frontend and backend, supporting user authentication, limit order matching, real-time candlestick charts, and wallet management.
- Built exchange frontend UI using React 19 + TypeScript + Vite, implementing candlestick charts (lightweight-charts), order book, order form, auth modal, and open/filled orders history panel.
- Built backend service with Hono + TypeScript (Bun runtime); PostgreSQL for user and wallet data, InfluxDB for candlestick time-series data.
- Implemented account authentication system with registration/login, JWT token issuance, and request auth middleware.
- Developed matching engine with order book model, price-priority matching logic, liquidity simulator bot, and multi-timeframe candlestick history in InfluxDB.
- Implemented wallet management system including balance queries, deposits, fund locking/unlocking, and automatic post-trade settlement.
- Handled server deployment with Nginx reverse proxy for frontend static assets and backend API; Docker Compose for PostgreSQL and InfluxDB container management.
