Why do programmers prefer dark mode? Because light attracts bugs! I’m a software engineer who specializes in full-stack applications and web design. I’ve successfully published multiple apps and websites, and I’m always excited to keep expanding my skills across modern development stacks. I genuinely enjoy taking an idea from a rough concept all the way to a clean, working product that people can actually use and enjoy. Still relatively early in my journey, but I’m loving every part of building and learning along the way.

I’m a CAD/CAM designer with real machine-shop experience, specializing in CNC-ready models, mechanical parts, fixtures, tooling, prototypes, and manufacturing-focused design. Unlike a designer who only models for appearance, I build files with the manufacturing process in mind. I understand mills, lathes, tooling, workholding, materials, tolerances, and the practical details that determine whether a part can actually be made. I can create or clean up STEP files, design functional parts, prepare models for CNC machining or 3D printing, and help turn rough ideas into usable production-ready geometry.
