Profile / 简介02

Yamaoka builds agent products end to end. VibeLingo proves conversational orchestration; CryptoTradingAgents proves reliable autonomous execution.

VibeLingo 解决对话智能体的编排与记忆问题；CryptoTradingAgents 解决自动执行系统的稳定运行问题。

Selected work / 核心作品03

Two products.
Two kinds of complexity.

Conversation intelligence.
Autonomous execution.

01 / LIVE PRODUCTAI LANGUAGE EXPERIENCE

VibeLingo

A multi-NPC dialogue engine where memory, safety and direction live inside one explicit state graph.

基于 LangGraph.js 的多 NPC 对话产品，将记忆、安全、工具调用与导演调度收敛为可追踪状态图。

TRACEMemory → Guard → Director

Long-term memory

Persistent context that survives individual dialogue turns.

RAG dialogue retrieval

Context-aware retrieval for grounded character responses.

Trace & evaluation

End-to-end traces plus an automated regression evaluation set.

02 / AUTONOMOUS SYSTEMCRYPTO EXECUTION

CRYPTO / AGENT7×24 RUNNING

SCAN→FILTER→SIZE→EXECUTE→MONITOR

Crypto
TradingAgents

Deterministic strategy execution, separated from LLM-based macro risk judgment.

将确定性策略扫描引擎与 LLM 宏观风控解耦，覆盖信号过滤、仓位缩放、执行和持仓监控。

Timeout retry & circuit-breaker fallback
Persistent state & recovery
Unattended 24/7 operation

Capabilities / 技术能力04

One complete
delivery loop.

Architecture, knowledge,
runtime and product.

让系统持续稳定运行

04 / SHIP

Product
Delivery

Python, Node.js and C# backends; SQL and cloud data; React, Next.js, Vite and Blazor interfaces.

让能力成为完整产品

THE ARCHITECTURE RULE / 架构原则

Use models for judgment.
Use systems for certainty.
