I help startups and SMEs ship production-ready IoT devices—from custom PCBs to ESP32/STM32 firmware and BLE/Wi-Fi/MQTT cloud connectivity. What you get: fast prototypes, DFM-ready layouts, robust C/C++ firmware, and clear documentation (schematics, BOMs, test plans). Specialties: Low-power wearables, industrial automation (Modbus/RS-485), mobile companion apps (BLE), OTA update pipelines. Tooling: Altium/KiCad, FreeRTOS, PlatformIO, Zephyr, Saleae logic, JLCPCB/Seeed workflows. Proof: 100% JSS, 700+ logged hours, Top Rated Plus on agency (Octathorn). Typical results: cut BOM by 12–25%, shrink PCB by 20–40%, deliver first working proto in 2–4 weeks (scope-dependent). Let’s scope your device: share requirements, target cost, and constraints (size, battery, radios). I’ll propose a milestone plan in 24h.
