A RAG-powered chatbot embedded in this site, answering questions about site content with context-aware retrieval.

• Features: Context-aware chunking via LLM, with scope-wide summary generation.
• Tech Stack: Built with Vercel AI SDK, gemini-embedding-001 embeddings, and a PostgreSQL vector database.

Built a Coding Agent (like Claude Code) and an AI-SDK library in Minecraft using agentic coding. OC-CODE runs entirely in Minecraft and can complete complex tasks like drawing a 3D spinning cube on screen or building a 3D Hilbert curve in Minecraft.

A Discord receipt-extraction bot that converts receipt photos into spreadsheet-ready line items to speed shared-expense bookkeeping. Now extended with PriceRag — a RAG-powered price history search using OpenAI embeddings and PostgreSQL pgvector with HNSW indexing. Built with Azure Document Intelligence, Discord, Node.js, and OpenAI GPT-4o Function calling. Helped us with bookkeeping for 2 years.

A Discord bot that turns cooking videos into standardized recipes to make daily cooking easier. Accept Youtuve videos with or without subtitles, and transcribe audio in parallel, and cut processing time by 60%, while keeping it free to use. With the help of Spec coding, I rebuilt the program several times with ease as ytdl-core and fluent-ffmpeg depreciated.

• Tech stack: Discord bot, Cloudflare AI, whisper, Gemini.

A benchmark note that compares automatic speech recognition (ASR) services on price, accuracy, and speed. Used Postman to compare OpenAI, Azure, Cloudflare, LemonFox, and a self-hosting solution using Postman.
