C Developer

Systems Software Engineer — Novatech Systems

Seattle, WA | July 2023 – Present

• Refactored a core C network socket library using POSIX threads and select/poll APIs, resulting in a 28% increase in concurrent connections and a 15% reduction in packet drop rate under peak loads.
• Designed and implemented 4 custom Linux kernel driver modules for proprietary PCIe data acquisition boards, achieving 99.98% hardware reliability over a 12-month staging and production test period.
• Optimized memory allocation routines within a legacy embedded device control system, reducing peak memory usage by 40% and eliminating 12 distinct memory leaks using Valgrind and AddressSanitizer.
• Collaborated with a hardware design team of 5 engineers to write board support packages (BSP) for new ARM-Cortex M4 microcontrollers, cutting hardware bring-up time by 18 days.

C Programmer — Vanguard Robotics

Portland, OR | August 2021 – June 2023

• Developed and tested robotic control algorithms in C, reducing motor feedback loop latency by 32% and increasing robot movement precision by 15% across 4 prototype units.
• Created automated unit test suites in CUnit for 12 critical hardware interface libraries, improving overall code coverage from 64% to 92% and preventing regression bugs.
• Configured and maintained firmware build systems utilizing Make and CMake, reducing local clean compilation time by 35% and automating CI/CD pipeline runs for 8 active repositories.
• Analyzed serial interface protocols (RS-232, SPI, I2C) to build driver layers for 6 external sensors, leading to a 22% improvement in sensor data acquisition speed.
