Profile bio

About Lumen Sierra

I started out hand-copying BASIC programs into my TI-99/4A, and from then on I was hooked.  I took a brief detour into system administration, only to realize my first love has always been code.  Since then, I've developed a passion for clean code design, accessible UIs, and stable, easily-maintained apps.
