Cauã Diório

summary

Junior front-end developer at Loopscape, working on Loopvet, a system for veterinary clinics. My focus is motion and interface design. I study security through Sentinel Forge, my project that reads server logs and flags what looks like an attack. I use AI every day to learn faster and review the code carefully before it goes into a project.

experience

from front-end intern to junior front-end developer

• Built the internal CMS from scratch. One codebase runs several content portals for Loopvet and Domus, with a text editor, a public API and a link shortener that counts clicks.
• Handled the CMS security. Each person can only touch what their role and portal allow, and login uses two-factor authentication. Image uploads also block files made to take the server down.
• Built Loopvet's spreadsheet importer. It reads CSV and Excel, matches columns automatically or by hand, and shows a validated preview before importing.
