Senior Generative AI R&D Engineer · Audio Plugin Developer · Independent Musician
Building practical AI systems, audio plugins, and music technology for creators, communities, and intelligent workflows.

I work at the intersection of AI engineering, audio software, and creative technology. My projects span generative AI, RAG, agents, Physics AI, AIoT, browser-based music analysis, singing voice synthesis, and cross-platform audio plugin development for VST3, AUv2, and AAX.

I enjoy turning emerging AI and audio technologies into tools people can actually use, from livestream and Discord assistants to DAW plugins, music-analysis workflows, Traditional Chinese writing tools, portfolio systems, and polished web experiences.

Open to collaborations in generative AI, RAG, creator tools, and music technology.

Web experiences    Next.js, React, TypeScript, Tailwind CSS, GitHub Pages

Project	What it does
ai-interview	A multilingual AI engineering interview platform with source-linked flashcards in Traditional Chinese, English, and Japanese, structured AI-assisted study notes, community contributions, and daily incremental updates via GitHub Actions.
music-detection	A privacy-first browser music analysis tool that detects BPM, time signature, key, and vocal pitch range with ONNX inference, previews beat and pitch results, and exports Tempo + Lead Vocal MIDI, with an optional local Python engine.
HT-76	A JUCE-based 1176-style FET compressor for macOS and Windows, with Rev D and experimental Rev H circuit models, VST3, AU, and AAX builds, plus switchable classic rack and real-time analysis views.
JS_Inflator (customized fork)	A cross-platform JS Inflator fork with macOS and Windows VST3, AUv2, and AAX builds, installer packaging, and audio/UI regression testing; its AAX adaptation targets Pro Tools Developer and remains in testing.
software-salary	Taiwan software salary insights based on 709 analyzed salary samples, with market percentiles, company rankings, experience-based estimates, interview guidance, and 83 GitHub stars.
Private RAG / Agent Systems (private)	Internal AI systems for retrieval-augmented generation, document workflows, structured outputs, and production-facing automation.
twitch-bot	An OpenAI Responses API-powered TwitchIO EventSub chatbot with creator-persona prompts, configurable reply rules, cooldowns, viewer context, owner commands, token validation, and offline-aware behavior.
dc-manager	An LLM-powered Discord community assistant for rule-violation detection, configurable moderation responses, channel analytics, activity summaries, member tracking, and Traditional Chinese operations.
