Philippines

Message

At Vava Software Corporation, I engineered and maintained three decoupled Laravel applications connected to a centralized MySQL database: a customer-facing portal, a back-office administration suite, and an automation engine.

I built dynamic dashboards with Vue.js and improved client portals using jQuery, JavaScript, and Tailwind CSS. I also separated cron tasks, queues, and batch routines from user-facing traffic with a headless Laravel application.

At Bank of Makati, I maintained native PHP enterprise applications and optimized Oracle database performance and security. I also configured AWS EC2 Linux infrastructure and supported enterprise banking systems.
