Hi, I'm Harry ๐Ÿ‘‹

High-school maker who likes turning messy real-world problems into clean code.
Open-source hardware & tools ยท interested in physics, math, and engineering.
Currently: shipping the FindItem hardware project and a few small Python tools.

Python C++ Java JavaScript

ESP32 Arduino MQTT FastAPI Spring Boot Streamlit

Git GitHub Actions VS Code Windows PowerShell

๐Ÿ”ง What I build

  • ๐Ÿค– Hardware / IoT โ€” ESP32-C3 firmware over MQTT; real devices that light up and beep
  • ๐Ÿ Python tools โ€” CLIs & libraries with tests, packaging, and CI
  • ๐Ÿ“Š Data analysis โ€” hypothesis-driven, and honest about what the data does and doesn't show

๐Ÿ“Œ Featured projects

FindItem pantrypath
viralens findit-website
  • FindItem โ€” decentralized parts locator: search a part, the right storage bin lights up and beeps (ESP32-C3 ยท MQTT ยท FastAPI / Spring Boot)
  • pantrypath โ€” cheapest ingredient-substitution chain modeled as a shortest-hyperpath problem (Python ยท no ML, no API)
  • viralens โ€” hypothesis-driven analytics for Bilibili / YouTube creators
  • findit-website โ€” the open-source landing page for FindItem

    Open-source decentralized parts locator: search a part and the right storage bin lights up and beeps. ESP32-C3 firmware + FastAPI / Spring Boot backends over MQTT.

    Java 2

  3. pantrypath pantrypath Public

    Out of an ingredient? PantryPath finds the cheapest substitution chain by modeling cooking substitutions as a shortest-hyperpath problem. No ML, no API: offline and explainable.
