Ezequiel Santos

Apple Platforms Developer

Hi, I am Ezequiel.

Ezequiel is Ezekiel in Portuguese.

I have worked with technology since 2008, when I started as a mechatronics intern. After a few years in the industry, I joined the Apple Developer Academy in 2013 and started developing for iOS.

I still make small, useful software for Apple platforms. Some is for work. Much of it exists because I wanted it to.

Apps for academic work.

During my master’s and now my PhD, I have built small apps for the academic problems I encounter.

  1. Your citation profile

    Citatum is the neuter form of citatus in Latin, meaning something cited. The name keeps the focus on the work being cited and the record that grows around it.

    Citatum

    • iPhone
    • iPad
    • Mac

    Keep a quiet eye on your citations, h-index, i10-index, and the publications receiving attention, without repeatedly checking Scholar.

  2. Your publishing pipeline

    Auctorium is Latin for a supplement to a body of work. That idea shapes the product: a calm layer that adds structure and context without stealing focus from the research itself.

    Auctorium

    • iPhone
    • iPad
    • Mac

    Move every paper from first idea to published work, with venues, submission states, deadlines, reminders, and the next decision in view.

  3. Your reference library

    Repertum is the neuter form of repertus in Latin, meaning something found or discovered. It suits a library built around finding, collecting, and returning to sources.

    Repertum

    • iPad
    • Mac

    Turn DOI, PMID, arXiv, HAL, and GitHub identifiers into an organised, editable citation library that stays in sync across Mac and iPad.

  4. Your academic opportunities

    Opportunum is the neuter form of opportunus in Latin, meaning something suitable, favourable, or timely. It reflects an opportunity that arrives at the right moment.

    Opportunum

    • iPhone
    • iPad

    Discover academic positions, scholarships, grants, and calls that match where your research is heading, then save the ones worth pursuing.

Old projects.

Some of my older projects live here. They include one that Ryan Hoover, founder of Product Hunt, called “Such an obvious/brilliant idea.”
