If your project requires deep low-level engineering expertise, I can help you design, build, debug, and ship it properly.

⚙️ I turn silicon and specs into smart, stable, and scalable embedded solutions. I engineered a 30% improvement in firmware responsiveness across connected devices, helped reduce development time by 25% for a FreeRTOS based ESP32 product line, and built modular driver architectures that made it easier for hardware teams to scale from prototype to production, all while keeping performance rock-solid in the field. As an Embedded Firmware Developer & Embedded Systems Specialist with 7+ years of experience, I design and build fast, reliable, and maintainable embedded software and microcontroller firmware for IoT and industrial products using ESP32 / STM32 / nRF52, FreeRTOS, ESP-IDF, and ARM Cortex-M architectures. 💼 What I Offer: 🔹Production-grade microcontroller firmware using C/C++ for MCUs and SoCs (ESP32, STM32F4, nRF52, ATSAM4, etc.) 🔹FreeRTOS / ESP-IDF-based systems, leveraging multi-threaded architectures for improved efficiency 🔹Advanced sensor & peripheral drivers, integrated into complex hardware ecosystems 🔹Communication stacks built on SPI, I2C, UART, BLE, MQTT, CAN, USB, Ethernet 🔹Smart devices & cloud-connected IoT products using the Espressif ESP-IDF framework 🔹Industrial automation firmware and embedded Linux/AOSP customizations (Yocto, HALs, board bring-up) 🔹Thorough documentation & end-to-end support for internal and external stakeholders 🛠️ What I’ve Been Delivering When most teams reach out to me, they already have hardware in hand, what they don’t have is firmware they can trust in the field. So I come in, analyze what’s running, and turn “demo” firmware into production ready systems. That means: ✔ Optimizing edge-device firmware so it stays stable, responsive, and power-efficient ✔ Customizing AOSP / Embedded Linux platforms for real-world products (HMI panels, smart displays) ✔ Writing and integrating drivers for complex sensors and peripherals ✔ Handling board bring-up, BSP development, bootloaders, and kernel-level debugging ✔ Providing long-term maintenance to keep real-time systems healthy in industrial, consumer, and automotive environments My role is simple: make sure your embedded product behaves perfectly not just on your bench, but in your customer’s hands. 💻Embedded Systems Expertise Languages: C, C++, Python (tooling & scripting) MCUs & SoCs: ESP32, STM32 (F0/F4), nRF52, ATSAM4, ARM Cortex-M OS & Frameworks: FreeRTOS, ESP-IDF, Zephyr, Yocto, Buildroot Connectivity & Protocols: SPI, I2C, UART, CAN, BLE, MQTT, Ethernet, USB Tools: GCC, OpenOCD, JTAG/SWD, Logic Analyzers, Git, Jira If you’re building something that doesn’t fit the usual embedded mold, I’d be glad to hear about it. Some of my best work has come from partnering with teams tackling problems that require a custom-crafted solution. Let’s connect and take your project to the success it deserves.
