Rangkai – Open Source Marketplace for Global Small Businesses
Rangkai Protocol is a modular, decentralized marketplace framework that separates responsibilities across layers—identity, transactions, reputation, logistics, trust & compliance, and governance. It enables automated dispute resolution, ratings, and hybrid KYC/anonymous interactions. Reference clients showcase how buyers, vendors, and logistics providers interact with each layer, serving as templates for real-world implementations. Multiple reference clients illustrate different business models, including general commerce, builder platforms, and logistics coordination.

Sourdough Sensor – IoT starter monitor
IoT device that tracks a sourdough starter's rise, temperature, and humidity in real time. Detects the feed-to-peak-to-fall cycle, sends telegram alerts when it peaks or is about to overflow, and hosts a local web dashboard with a 24-hour chart. Learns your starter's typical cycle over a few feeds and predicts the next peak.
- Hardware: ESP32 DevKitC + SHT31 (temp/humidity) + VL53L0X (time-of-flight distance) + tactile button, mounted on a mason jar lid.
- Software: Arduino C++, embedded web dashboard, NVS persistence across reboots, telegram bot for push notifications.
- Built in collaboration with claude (chat) and buzz.xyz (agent harness) — a study in human + AI co-development.
