With 3+ years of hands-on experience, I specialize in taking embedded products from prototype to mass production. I've completed 10+ real-world projects and successfully shipped consumer products that are now in end-users' hands. What I Do Best I build production-grade firmware — not hobby projects. My work spans the full embedded stack: hardware bring-up, device drivers, firmware, bootloaders, OTA systems, and companion mobile/PC apps. Core Expertise - MCU Platforms: STM32 (F0/F1/F4/L0/L4), ESP32/ESP32-S3/ESP32-P4/ESP32-C3, nRF52480/NRF52832, ARM Cortex-M & RISC-V, ... - RTOS & Bare-Metal: FreeRTOS (advanced task sync — queues, semaphores, event groups, task notifications), bare-metal programming, custom bootloader development, ... - Peripherals: I2C, SPI, I2S, UART, PWM, ADC/DAC, RMT, Modbus RTU, USB HID, ... - Connectivity: Wi-Fi, BLE, LoRa, NFC, GSM/GPRS, NB-IoT, 4G, ... - IoT & Cloud: MQTT, HTTP/HTTPS, WebSocket, TCP/UDP | Azure IoT, AWS, Firebase, ... - Security: Secure Boot, encrypted NVS storage, FIDO2 passwordless authentication - Languages: C/C++ (primary), Python, Dart/Flutter (mobile & desktop apps), Java - Sensors: Accelerometer, IMU, Gyroscope, Time-of-Flight (ToF), Fingerprint, Ambient Light, Temperature, Humidity, Water Quality, Gas, Heart Rate & SpO₂, ... - Peripherals: Camera, Microphone, Speaker, Buzzer, ... - Displays: TFT, OLED, LCD, HMI, ,.. - Build & Debug: ESP-IDF, Makefiles, CMake, linker scripts, GCC toolchain, GDB/JTAG — fully IDE-independent - Other: Embedded Linux (Raspberry Pi, Orange Pi), Edge AI on MCUs, VoIP, WireGuard VPN, OTA update systems, PCB design (EasyEDA) What Sets Me Apart I deliver production-ready firmware, not proof-of-concepts. Clean architecture, proper error handling, memory optimization, and power management. I work at the toolchain level — Makefiles, linker scripts, GCC, GDB — not dependent on any IDE. I collaborate effectively with backend teams, including building systems using MCP (Model Context Protocol). I've shipped real consumer electronics — I understand what it takes to go from "it works on my bench" to "it works in 10,000 units." If you're a startup building a hardware product and need someone who can take it from prototype to production, let's talk.
