About

Developer who designs

I'm Ralph, a 3rd-year BSIT student at the Technological Institute of the Philippines – Quezon City (TIP-QC) and a developer on client projects, including work for CALLED Presentations.

I shipped a Flutter app to the Google Play Store production track and took it through iOS App Store submission without owning a Mac, using cloud CI (Codemagic) and remote Mac sessions.

Before I wrote production code, I spent 3+ years on graphic design: branding and UI/UX. I still design what I build, from Figma screens to the final product.

What I build

  • Mobile apps in Flutter, shipped through the app stores
  • Full-stack web apps with auth, payments and email
  • Booking, ticketing and ordering systems
  • Landing pages and microsites
  • UI/UX design in Figma
