I’m building a portfolio of projects spanning edge intelligence, secure networking, and developer tools as an independent builder.
Every project is built from scratch — I write the code, validate the hardware, and ship the product myself. Below are all projects by category — open one for the technical details and progress.
A learning playground with 10 mini-games covering math, English, science, logic, and puzzles, with Google sign-in and a score dashboard; built with React, Go, and PostgreSQL.
An AIATCL literacy practice site with five mock exams and one supplemental set, plus timed scoring, explanations, a wrong-answer notebook, and topic analysis.
A lightweight English practice site for Jingxin Grades 4–5, with four test sets, illustrated vocabulary and reading, TTS listening, daily missions, and seven achievement badges.
An online question-bank practice site covering seven subjects across two iPAS certifications — AI Application Planner (Associate & Intermediate) and AIoT Application Engineer (Associate) — with 2,222 questions, three practice modes, per-option analyses and study notes.
An interactive insect observation report system for elementary students, with online journaling, hand-drawing, photo upload, and growth-curve analysis, plus an A4 print layout for school homework.
A self-study site about frozen desserts, in four areas: taxonomy, science, technique and a recipe calculator. Every recipe number comes from a calculator compiled from Rust to WASM, never written by hand or generated by an LLM.
macOS AI dictation app. Press a hotkey, speak, and get polished text inserted anywhere.
Lectio is a macOS voice learning companion that reads selected text or the current screen, then lets learners ask contextual questions out loud.
AI-driven embedded development automation — closing the loop between AI agents and physical hardware.
Embedded crypto and communication framework on ESP32 with post-quantum-ready messaging.
Post-quantum hybrid VPN tunnel combining X25519 + ML-KEM-768, 138 tests passing.
Distributed edge platform with batch signing, backoff-retry uplink, and offline spill recovery.
AI-Maker platform: ML pipeline, Studio UI, and MCP server with 7 tools.
