Experience

  • Kable

    A Discord bot providing integration with TikTok.

    I utilized web scraping to retrieve information from the TikTok website and designed a proxy management system to avoid being blocked. As the sole developer, I talked with users to fix bugs and implement requested features.

  • ETHSBell (via codETHS)

    ETHSBell tells students when the current period will end. It's beneficial since the school has multiple bell schedules depending on the day, and it can be hard to remember all the start and end times. In addition to the website, a Chrome extension provides easy access to the current period and schedule information. It also has an API to allow for other projects to integrate with it, such as the PE Board.

    I primarily worked on the front-end website and Chrome extension, but I also helped with the back end.

  • PE Board (via codETHS)

    The PE Board tells ETHS students which gym their class will be in. Staff can input their locations in a Google Sheet and what students need to bring to class. It uses ETHSBell to display the current period. The board is shown on a monitor at the entrance to the gym, and students can access it on their Chromebooks or phones.

  • Kitcoin (via codETHS)

    Kitcoin is a digital currency for students at ETHS. Staff can send Kitcoin to students, which they can spend at the school store. Its Google Classroom integration makes it easier for teachers to send Kitcoin to students in their classes. Students can see their balance, transaction history, and what items are available in the store.

    I worked on all project parts, including leading a team of five other developers.

  • Guess the Salary

    Guess the Salary is a game for the Hoya Hacks 2022 hackathon to spread awareness of wage inequality. The game's goal is to guess the average job salary in a given city.

    I worked on the back end and front end with one other developer to complete this project.

  • Guess the Color

    Guess the Color is a web game where you guess which color matches the given hex color code. There are three different modes, with higher difficulties having more similar-looking colors. There is a singleplayer version (https://albertp.dev/guess-the-color/) and a multiplayer version (https://albertp.dev/guess-the-color/multiplayer) where once a person can see the color options and other people have to describe the color from the hex code. I was the sole developer on this project.
