A highly-motivated Full-Stack Engineer and natural troubleshooter who thrives on solving complex, multi-disciplinary problems. My core drive is pragmatic problem-solving: I apply a "MacGyver" approach to find and fix inefficiencies by improving the tools and systems you already have. I focus on high-ROI automation, targeting repetitive, time-consuming tasks while avoiding the trap of over-engineering simple fixes. With 6+ years of engineering and a proven background in business/team leadership, I bridge the gap between hands-on technical execution and strategic, results-driven thinking.
