Senior Firmware Engineer @ Eaton | Pioneering Gen AI SDLC Orchestration & Zephyr RTOS Platforms | Turning Silicon into Intelligent Systems

About

Most embedded software teams are trapped in a legacy paradox: they are building next-generation hardware using agonizingly slow, fragmented, and outdated development cycles. When a single firmware bug can delay a multi-million dollar product launch, relying on manual testing, siloed codebases, and rigid processes isn't just inefficient—it’s a massive business liability. I bridge that gap. As a Senior Firmware Engineer with 9 years of experience, I specialize in architecting resilient, production-grade systems using Zephyr RTOS and FreeRTOS while radically accelerating the software development lifecycle through Generative AI orchestration. Throughout my career—spanning critical projects for global giants like Eaton, Alstom, and Bombardier—I have consistently engineered high-leverage solutions to complex hardware and software bottlenecks: 🔹RTOS Platform Architecture: Designing and scaling Zephyr RTOS-based platform software for complex, multi-product deployments across target MCUs like the STM32H7 and STM32U5. 🔹AI-Driven Engineering: Actively transforming embedded engineering workflows as part of Eaton's Dhruva AI team, building AI SDLC orchestrators to optimize software delivery. 🔹Low-Level Precision: Deep expertise in Linux internals, custom Yocto build systems, custom package recipes, bootloaders (Mcuboot), and a wide array of MCU architectures. 🔹Track Record of Impact: From slashing 9,555 production errors for an enterprise client to co-developing magnetometers for space research applications, I build software that performs under absolute constraints. Whether I'm writing optimized C/C++ for an ARM Cortex core or leveraging cutting-edge LLMs to streamline the embedded pipeline, my goal is always to deliver robust, secure, and intelligent firmware.
