C Software Engineer

Systems Software Engineer — CoreKernel Solutions

Bellevue, WA | June 2023 – Present

• Architected a custom multi-threaded network socket routing daemon in C, increasing data packet processing throughput by 42% and reducing average network latency from 14ms to 8ms for 500k+ concurrent IoT connections.
• Redesigned memory-mapped database caching systems, implementing lock-free data structures that eliminated race conditions and reduced memory utilization overhead by 28% across a cluster of 80 production servers.
• Analyzed codebases using Valgrind and GDB to identify and resolve 14 critical memory leaks and pointer corruption bugs, improving daemon uptime from 94.2% to 99.98% over a 6-month period.
• Integrated secure programming practices following CERT C coding standards, reducing vulnerability scan findings on legacy modules by 73% and eliminating 8 potential buffer overflow vectors.

Embedded Software Engineer — Novatech Microdevices

Seattle, WA | June 2021 – May 2023

• Developed bare-metal microcontroller firmware in C for 4 medical monitoring devices, optimizing boot routines to reduce device startup time by 35% and saving 64KB of flash memory allocation.
• Authored low-level device drivers for SPI, I2C, and UART peripheral buses, decreasing data transfer error rates by 54% and stabilizing sensor read frequencies at 100Hz across 12 product builds.
• Optimized assembly-critical pathways in compiler configurations for ARM Cortex-M processors, accelerating mathematical computation execution speed by 19% across all telemetry profiles.
• Coordinated with a 5-member QA team to build automated unit testing frameworks with Unity, raising code coverage from 68% to 91% and identifying 23 integration regressions prior to production.
