Every point-of-sale terminal in a venue runs off configuration nobody in the stands ever thinks about — pricing, menus, tax rules, hardware mappings — and it has to hold up the moment gates open at a 100,000+ seat stadium. There's no maintenance window mid-event: the terminals need to be right before doors, and the sales data feeding back has to stay accurate in real time while thousands of transactions run concurrently.

I build and maintain the pieces that make that possible — the application logic driving configuration, the queries that keep live sales numbers trustworthy under load, and the cloud infrastructure it all runs on, provisioned and versioned rather than hand-maintained, so a bad deploy or a dead node doesn't become a multi-hour incident during a sold-out show. As the only engineer on the team working US hours, that responsibility doesn't stop at code review — it's disaster recovery late at night, technical calls with clients who need an answer now, and travel on short notice when a venue needs someone on-site.
