I've built and led Quero Passagem's hotel booking product in Laravel, helping scale it from zero to R$ 2 million in revenue.

As Tech Lead, I architected a PHP 8/Laravel meta-search service for high request volume, integrated front-end experiences in Angular and React, and defined patterns for distributor and payment gateway integrations.

I optimized high-traffic MySQL queries from 1 second to 0.09 seconds, expanded Redis caching for critical routines, and automated Zabbix observability scripts that tripled monitored metrics in two months.

Earlier, I delivered PHP/Laravel systems for clients including CREA-DF and Horsch, and I also build Sebastian, an open-source Node.js and Express AI agent for tailoring resumes and cover letters.
