⚙️ 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.

Embedded Systems | Embedded Linux & Android Systems Engineer | Linux · Yocto · Qt/QML · AOSP · Android Automotive · Android Development · ADB Automation · C/C++ · Python · Java · Kotlin If you're building a product that runs Linux or Android under the hood - from an embedded device to an infotainment system - and you need someone who understands every layer from the hardware up, I can help you ship it. I specialize in the space most engineers avoid: the gap between hardware and the software stack. That means I can trace a boot failure to a kernel driver, customize an AOSP build from scratch, fix a VHAL service that drops vehicle signals, or write Python tooling that replaces hours of manual ADB work across a fleet of devices. What I work on: - Embedded Linux - Yocto, BSP bring-up, driver development, cross-compilation - AOSP builds and system-level customization (permissions, overlays, HALs, system services) - Android Automotive OS - VHAL, AIDL interfaces, CarService integration - Python ADB automation - multi-device control, test frameworks, CI scripting - Android app development in Kotlin/Java when the project needs it - Boot, performance, and crash debugging across hardware and software layers - Docker environments for reproducible builds and clean dev workflows Why this matters for your project: Most engineers are strong at one layer - app, firmware, or Linux. I work across all of them. That means I catch integration bugs that fall between teams, and I can translate clearly between hardware and software sides so nothing gets lost. Recent work includes Android Automotive infotainment systems, AOSP-based product customization, and Python automation tools for multi-device QA workflows. If you're dealing with a system-level issue, need an embedded Linux or Android build customized, or want automation that actually works at scale - let's talk.
