At Zerviz SpA, I refactored encryption for the ChileAtiende portal using AWS KMS asymmetric keys, migrated the portal to the latest Laravel version, and built an impersonation system for the Somos application.
Previously, at VirtualPOS SpA, I designed and built Quick Checkout, which increased purchase conversion by up to 80%. My work spans PHP applications for payments, banking, and public-sector services, including Laravel and Lumen development, testing, and deployment.
