hello — i turn hardware headaches into firmware that talks & acts. be curious.
- EMS Mesh — FreeRTOS-based self-healing ESP-Mesh-Lite clusters (50+ nodes, <500ms latency)
- NILM Edge — active learning energy disaggregation via kHz V-I trajectory sampling
- Wi-Fi CSI Radar — privacy-first presence sensing through RF signal disturbances
- µC Agents — TinyML at the edge, sensing & acting through personal awareness
