STM32/ESP32 Embedded & Hardware Engineer | IIoT Firmware + PCB Design I help companies, startups, and individual clients build reliable STM32/ESP32-based embedded and IIoT products, covering both firmware and hardware — from concept to production-ready systems. My core expertise is STM32/ESP32 firmware development in C / Embedded C using FreeRTOS, combined with schematic and PCB design for connected devices (power, MCU, sensors, relays, and interfaces). I focus on stable, production-grade systems with attention to power integrity, real-time behavior, connectivity reliability, and edge-case handling. Typical deliverables: – STM32/ESP32 firmware (FreeRTOS, Wi-Fi, BLE, MQTT) – Hardware-aware firmware (startup, brown-out, watchdogs, EMI considerations) – Schematic & PCB design ready for manufacturing – Clean, maintainable code and documented designs suitable for long-term products In parallel, I am actively expanding projects using Nordic nRF (BLE), and Raspberry Pi, applying the same system-level engineering principles to new platforms. If you need someone who can own both hardware and firmware, communicate clearly, and deliver something you can actually ship, let’s discuss your project.
