I'm a builder, engineer, and developer. I like turning fuzzy ideas into working systems: AI agents, developer tools, infrastructure, and small utilities that make daily engineering feel lighter.
- tiny-rag-lab - a learning-first RAG engine with visual tools for exploring classic RAG mechanics through code, traces, and playback.
- tiny-corpus-workbench - an inspectable workbench for trustworthy and reversible corpus preparation before typical RAG processing.
- tiny-duo-infer - a learning-first LLM inference engine built from scratch in Python and MLX, with a local OpenAI-compatible Chat Completions API.
- tiny-gpt - built GPT from scratch through hands-on ML practice.
- neetcode-submissions - algorithm and ML practice notes from NeetCode.
- plan-build-review - a gated, role-based workflow, with independently reviewed plans, task-by-task delivery, and explicit approval checkpoints.
- human-in-loop-workflow - a simple, well-behaved workflow for human-reviewed agent work.
