I design and develop production-ready firmware for connected and embedded systems, with a strong focus on reliability, performance, and long-term maintainability. My work spans the full development lifecycle, including system architecture, firmware design and implementation, hardware bring-up, optimization, and deployment support for production environments. I primarily work in C and C++ for ARM Cortex-M, ESP32, and NRF52 platforms. Both bare-metal and RTOS-based approaches are used, especially FreeRTOS, to build deterministic and efficient embedded systems. This includes designing multitasking architectures, handling interrupts, and implementing low-level peripheral control for real-time applications. Strong experience with embedded communication protocols such as SPI, I2C, UART, CAN, BLE, and WiFi, along with development of custom drivers for sensors and external hardware. The focus is on stable integration and efficient operation in resource-constrained embedded environments. On the IoT side, I build firmware for secure and reliable connectivity between devices and cloud platforms. This includes MQTT-based telemetry systems, REST API integration, OTA update support, and low-power optimization techniques such as sleep modes, deep sleep, and duty cycling for battery-powered devices. I also handle hardware bring-up and system-level debugging to support early-stage development and integration between firmware and hardware. Close collaboration with hardware teams ensures smooth integration between PCB design and firmware behavior. In addition, I have experience in embedded AI and edge computing, including deploying TinyML models on microcontrollers. I work with startups, hardware teams, and product companies, helping take embedded products from early prototypes to production deployment, as well as supporting existing systems through debugging, optimization, and firmware evolution.
