About Gabriel Deruwe

I am a senior systems and debugger-focused software engineer with over 16 years of experience designing, implementing, and operationalizing debug, exception handling, and diagnostic infrastructure in mission-critical embedded systems. I work primarily in C, C++, and Python across embedded RTOS environments, with frequent interaction at the assembly and hardware interface level.I have deep experience in embedded networking systems, including ownership of Ethernet stack behavior across multiple products, driver-level modifications, and collaboration with stack vendors to diagnose and resolve complex issues. My work includes designing network architectures, analyzing protocol behavior under real-world conditions, and reproducing failures through custom tooling.I have also developed packet-level test frameworks using tools such as Scapy to replicate precise timing and protocol conditions, including full TCP session emulation and man-in-the-middle traffic manipulation to reproduce and diagnose field issues.I have worked extensively with compiler-generated code, analyzing instruction-level behavior, ABI interactions, and exception semantics across ARM architectures, with practical experience interpreting disassembly and debug formats such as ELF/DWARF to understand runtime behavior.My work focuses on making complex systems observable, explainable, and diagnosable under real-world conditions. Since 2019, I have led a multidisciplinary team investigating rare, high-impact field failures, requiring deep analysis of control flow, memory behavior, and system interactions across hardware and software boundaries.I am motivated by understanding how software translates into machine behavior and ensuring systems remain debuggable, reliable, and transparent even in failure. I also mentor engineers in systematic fault analysis and clear technical communication across disciplines.I am a named inventor on multiple U.S. patents spanning embedded systems, power system communication, and intelligent device interaction, with contributions ranging from early-career infrastructure systems to current work in system monitoring and analysis.Core Expertise • Embedded networking architecture, design, implementation, and diagnosis. • Low-level systems debugging and fault analysis • Instruction-level analysis of compiled code (ARM & Coldfire) • ABI, exception handling, and control flow semantics • Embedded RTOS and hardware/software interaction • ELF/DWARF-based debugging and disassembly analysis • C/C++ systems programming
