Tools for the job, by someone doing the job.
Generalist medical laboratory scientist with 10+ years on the bench and a heavy focus on transfusion medicine. I started building software in 2025 because I got tired of fighting bad tools and inheriting Excel sheets that outlasted their creators.

About
I'm Peter Le, MLS(ASCP)CM — a generalist medical laboratory scientist with a decade-plus on the bench and a heavy focus on transfusion medicine. I've worked Transfusion Services, a Blood Support Detachment, and the general clinical lab. "Crusty NCO" is self-effacing; the actual posture is professional, inquisitive, and quietly allergic to bullshit.
I started building software in 2025 because I got really tired of fighting bad tools and inheriting Excel sheets that outlasted their creators. Coding is almost exclusively with Claude Code these days — not an endorsement, just the honest answer. Nothing else got close without asking me to set fire to thousands in API costs (a lesson learned the hard way on early RooCode).
I build on personal time, or while multitasking when the shift allows. The apps here exist because I needed them to.
I build for the little guys. The middle managers told to do more with less. The techs and NCOs who want their work lives to be easier — because, honestly, I'm trying to facilitate laziness in the best possible sense: less busywork, fewer clipboards, more time for the parts of the job that actually need a human.
If a workflow on your end is held together by spreadsheets and good intentions — particularly anything involving inventory, accountability, or barcode scanning — I'd like to hear about it.
