QR-driven warehouse inventory
Live inventory across five storage units, tracked by scanning a QR code on every box.
I automate the parts of a business that still run on somebody remembering.
Full-stack software engineer. Scan a box in a warehouse and the count updates for everyone at once. Edit a product and the next order prints a corrected packing slip.

Selected work
Sixteen systems, and the operational problem behind each one.
Most of this is internal tooling, so there isn’t much to screenshot. Each case study diagrams what happens instead.
About
I learn by shipping, then maintaining what I shipped.
I started writing Lua scripts for FiveM game servers as a kid. That’s where I learned to program, by needing something to work and refusing to stop until it did.
These days most of my work is operational: the tooling a business runs on rather than the site its customers see. One system knows which of five storage units a box is sitting in. Another turns an afternoon of product-photo editing into a single command. None of it has a landing page.
I work across the stack because these problems don’t respect boundaries. A QR scan is worth nothing without the database behind it, so I ended up writing both. I use modern tooling, AI included, the way I use a debugger or a docs tab: it makes me faster, and it doesn’t make the decisions.
No degree and no bootcamp. Everything here is something I built and still keep running.
