Hendrizzzz/README.md

Hi, I'm Hendrizzzz

Computer Science student at Saint Louis University in Baguio, Philippines.
I build browser extensions, backend APIs, and local-first developer tools.

I like shipping practical software, especially tools that automate annoying workflows, improve privacy, or make everyday systems more reliable.

Focus

  • Backend development with Java, Spring Boot, REST APIs, SQL, and PostgreSQL
  • Browser extension development with JavaScript, Manifest V3, content scripts, Chrome APIs, and browser storage
  • Local-first tools for privacy, automation, diagnostics, and Windows developer workflows
  • Testing and quality practices with Playwright, pytest, ruff, validation, and structured debugging

Featured Work

Ghostify

MIT-licensed Manifest V3 privacy controls for supported Seen, Typing, and Story View signals on Instagram, Facebook, and Messenger web. Ghostify has 4,000+ users listed on the Chrome Web Store and is also published through Microsoft Edge Add-ons. Its privacy controls run in the browser; the popup may fetch a public, display-only verification status.

  • Published a Manifest V3 extension with 4,000+ users listed on the Chrome Web Store and a Microsoft Edge Add-ons listing
  • Built in-browser privacy controls that require no Ghostify account or social-media password
  • Implemented content scripts and declarative network rules for supported social platforms
  • Added browser-local settings storage for per-feature controls
  • Added regression, packaging, and release checks for Chromium and Firefox targets
  • Built and deployed a public landing page for the extension
