// Test Engineering × Full-Stack Software

I build the systems that measure, test, and run the factory floor — from automated functional test equipment to MES platforms — turning hardware and software into tools that lift yield, cut cycle time, and make production traceable.

Between the probe and the code

An electronic systems engineer who ships software. I sit where hardware meets the stack and build the integrated systems in between.

I'm a solutions-focused engineer with hands-on experience bridging hardware and software to create integrated systems that deliver real business value. My background in electronic system engineering, combined with full-stack development, lets me approach problems holistically — from the fixture on the bench to the dashboard on the wall.

I've led cross-functional work on test monitoring systems, CAPA tooling, and machine troubleshooting that consistently produced measurable improvements in productivity, quality, and efficiency across the line.

My approach pairs Lean Six Sigma discipline with modern software practice, so solutions aren't just technically sound — they're practical and sustainable for long-term operations.
