Builder
Building AI-native products, autonomous agents,
and developer tools.
Currently focused on quantitative systems, publishing workflows, and open-source AI assistants. Interested in AI, robotics, digital biology, and frontier technology.
iOS engineer turned AI-native builder. I design and ship products that sit at the intersection of autonomous systems, developer experience, and quantitative reasoning.
I believe the most impactful tools are the ones that disappear into the workflow.
Projects
Selected work across autonomous systems, publishing workflows, and developer tools.
Products
QuantPilot
Autonomous quantitative trading platform focused on agent-driven decision workflows.
Publio
Multi-platform publishing tool for writing once and distributing everywhere.
Obsidian Plugins
Smart Explorer
Alternative file explorer with custom sorting, grouping, filtering, and lightweight previews.
Vault Inspector
Vault health checker that identifies broken links, orphan attachments, duplicates, and frontmatter drift.
Document Exporter
Export notes and folders as Markdown bundles, HTML documents, or print-ready PDFs.
Open Source
Open-source projects I contribute to.
OpenClaw
Selected Contributions
Telegram non-streaming media deduplication
Fixed duplicate MEDIA: attachment delivery in Telegram non-streaming mode by tracking block-sent media URLs, filtering final reply payloads, and covering the pure deduplication path with regression tests.
TUI streaming watchdog reconnect recovery
Resynced the TUI streaming watchdog after reconnects, kept active tool and lifecycle events as proof-of-life, and added regression coverage for stale reconnect runs.
WhatsApp DM voice-note transcription
Restored preflight speech-to-text for WhatsApp DM voice notes so agents receive spoken text instead of raw <media:audio> placeholders when transcription succeeds.
OpenChronicle
Selected Contributions
Compact overwriting concurrent writes fix
compact_file LLM rewrite could overwrite entries appended by concurrent reducers. Added compare-and-swap writeback: re-read the file under per-file lock before writing, skip compaction if changed, and refresh FTS rows atomically inside a SQLite savepoint.
Writing
Thoughts on engineering, AI, and tools.
MiniCPM ：端侧 LLM 的效率路线
从 MiniCPM4、InfLLM-V2、SALA 到 BitCPM4，梳理 MiniCPM 系列在端侧推理和长上下文效率上的技术取舍。
Google Gemma 4：一次真正意义上的代际跨越
Gemma 4 四种尺寸全系列原生多模态，Apache 2.0 开源，Agent 能力 +1200%——不只是性能提升，是结构性跨越。
Harness Engineering：AI Agent 时代真正缺的那块拼图
Harness Engineering 不是新模型也不是新框架，而是一种工程思路的命名——让无数工程师感到如释重负的命名。
Strategy Gene：让 Agent 真正学会而不是记住
基于 arXiv:2604.15097，探讨如何通过 Strategy Gene 让 Agent 系统真正习得策略，而非依赖文档堆叠的硬编码记忆。
