Luiz Chaves

Full-stack developer connecting WordPress, commerce and the systems behind them.

About

I'm a full-stack developer based in Brazil, currently finishing a degree in Information Systems at Estácio de Sá. My work centers on WordPress — building both the frontend people see and the backend logic that runs behind it, plus the server work that keeps it fast and online: hosting, backups, performance, maintenance.

I got here through administration, not a computer science track. That background shows up in how I build: every integration starts with the business process it needs to support, not the other way around. It's part of why I end up gravitating toward the messier problems — validating a CNPJ against an external database, wiring a marketplace's vendor payouts, getting a lead from a form into a CRM without anyone touching a spreadsheet.

I'm still learning deliberately — courses, side projects, whatever the next problem requires.

Build

Connect

Wire it to whatever else it needs to talk to: a CRM, a payment gateway, an external API.
