Embedded Systems Engineer with 10+ years of hands-on experience in STM32, ESP32, and industrial IoT product development. I run a hardware/software R&D company in Turkey where we design and manufacture portable measurement devices for heavy industry — from bare-metal firmware and BLE communication stacks to C# WPF desktop applications that tie it all together. What I bring to your project: • STM32 (F4, H7, WB55) — FreeRTOS, DMA, ADC pipelines, USB HID, custom bootloaders • ESP32 — ESP-IDF, Wi-Fi/BLE, MQTT, sensor integration • BLE — Custom GATT services, multi-device architectures, MTU optimization • UI on embedded — LVGL, TouchGFX on SPI/parallel displays • Desktop software — C# WPF applications with BLE/USB connectivity • Industrial IoT — MQTT, InfluxDB, Grafana dashboards, Docker deployments • PCB-aware firmware — I work closely with hardware, so my code accounts for real-world constraints I've shipped products that run 24/7 on rotating kilns and industrial dryers — environments where reliability isn't optional. If your project needs someone who understands the full stack from sensor to screen, let's talk.
