Senior🎓
Top SchoolJeffrey Hufford is a hardware- and firmware-focused co-founder with 11 years of engineering experience building IoT products and infrastructure from PCB prototypes to cloud backends. Since founding Flume in 2015 he has led firmware development, protocol design for 2.4 GHz and 915 MHz bands, backend systems, and tooling to deliver a non-invasive water monitoring product with 5-second resolution and leak alerts. He combines hands-on embedded work (including improving MQTT reliability on ESP8266) with backend and scripting skills, bridging low-level device behavior and cloud services. Earlier internships at Cisco and technical support roles shaped his tooling and automation instincts, including building simulators and parsers for large-scale systems. Based in California, he favors pragmatic, test-driven engineering and often writes the small but critical fixes that keep connected devices reliable.
